Constant current diode "CRD E series (axial lead type)"

Constant current diode "CRD E series (axial lead type)"

High reliability with airtight sealing!

The "CRD E Series" uses components that provide stable constant current characteristics in a compact size. It is a small device that employs a DO-35 style DHD (Double Heatsink Diode) structure with a DO35 (300mW) package. With hermetic sealing, it offers high reliability, and the materials used are inexpensive and suitable for mass production. Previously, the series had a maximum of "E-153 (15mA)," but now "E-183 (18mA)" has been added. This allows for the supply of a constant current that does not exceed the rated current, making it possible to stabilize the brightness of high-brightness LEDs rated at 20mA with a single component.

Medical institutions should ensure to cut off unnecessary communications to protect their core from ransomware attacks.

Medical institutions should ensure to cut off unnecessary communications to protect their core from ransomware attacks.

The number of ransom demands and service suspensions due to ransomware infections is increasing. As IT advances, the risks also grow. Don't forget to implement effective intrusion and information leakage countermeasures.

It is said that with "zero trust, security measures are perfect and intrusion prevention through boundary control is outdated," but in the end, there are always security holes somewhere that can be exploited, leading to system reboots and taking days to restore data from backups during which nothing can be done, which often makes the news. There are even worse cases. The physical data diode OWCD provides hassle-free boundary control, but did you know that there are actually two ways to use it? One is to protect the core without allowing intrusions. The other is to prevent any data from being sent out, thus avoiding the actual damage from takeover. Ransomware relies on remote communication with the outside. By shutting that down, we can counteract data leaks and ransom demands for encrypted data. By combining it with access authentication and virus detection mechanisms, we enhance the overall availability of your medical system and protect your medical services. Not only in healthcare, but government agencies and companies that skillfully combine OWCD to strengthen their defenses while reducing costs are rapidly increasing, as are the SIers providing these solutions. We encourage your company to consider utilizing the physical data diode OWCD. Please also refer to our website. There are video explanations available! Check out the related links below, including contact information.

TVS (for USB2.0 to USB4 applications)

TVS (for USB2.0 to USB4 applications)

Choosing the appropriate TVS (Transient Voltage Suppressor) protects the product from latch-up.

With the development and improvement of USB interfaces and protocols, many smart products are adopting USB Type-C as their connection interface. This allows for the support of diverse video, audio, and data transmission at higher transfer speeds. At the same time, signal transmission has become more susceptible to interference from external power surges. Therefore, the use of TVS diodes for surge protection should be more stringent. However, if users pursue only TVS devices with low clamp voltages without considering other parameters such as operating voltage, there is a risk of affecting real-time communication on the Type-C interface or, in extreme cases, causing latch-up due to EOS (electrical overload), which could damage the circuit. To achieve proper and effective transient voltage surge protection in the interfaces of electronic products with complex signal and power lines, adding TVS diodes to the interface will be the most effective protection solution.

OWCD Remote Secure Link File Sharing

OWCD Remote Secure Link File Sharing

To securely obtain information in the supply chain, there are methods like this that can strengthen cybersecurity even with partners at different levels of response.

A data diode that restricts communication in one direction, specifically the physical data diode "OWCD" that truly cuts the line in one direction. By skillfully combining it, we can create a network that protects the supply chain. While the internet can be used in various ways, the critical systems can: - Shut out unauthorized intrusions from the source - Shut out information leaks from the receiving side Of course, it can also be combined with checking functions. Isn't it still common to attach PDF files to emails and send them to others? Perhaps sending via FTP? Even in situations where emails are simply accepted, utilizing OWCD to prevent leaks from that circuit is recommended. In the case of sending and receiving documents in the supply chain, placing OWCDs on both sides can strengthen the defense even further. If bidirectional communication is necessary, it can be addressed by establishing it mutually. The use of OWCD is increasingly being utilized by SIers in their proposals to customers. Please make use of it to strengthen your cybersecurity. For inquiries, please visit our company website through the related link below.

OWCD Utilization High Security Case: Remote Desktop

OWCD Utilization High Security Case: Remote Desktop

Isn't the remote line for system maintenance affecting the fate of the company? A new idea to physically seal off the "invasion point" of ransomware.

Our products physically block both external intrusions and internal information leaks. You don't need to be IT-savvy. We combine "peace of mind in connectivity" with "protective mechanisms." This is the security we want you to choose. Since data diodes are devices that control communication in one direction, bidirectional communication is not possible. However, because they are excellent devices for preventing unauthorized access from the source side, we often receive requests asking if there is a way to use them bidirectionally. VPNs, commonly used for remote maintenance, have become quite ineffective as a security measure on their own. We are often asked if it is possible to balance intrusion prevention with remote maintenance. This is where we introduce a high-security case utilizing OWCD: "Remote Desktop." By separating the contents of the communication used in the Windows service "Remote Desktop" and routing them through different paths, and by incorporating OWCD, we can prevent unauthorized access and intrusions to the source side. By combining with other security systems, we can achieve multilayered defense and minimize damage. We have received numerous inquiries from SIers. For inquiries, please visit our website via the link below.

OWCD for boundary control data diodes in IoT, production management, and healthcare operations.

OWCD for boundary control data diodes in IoT, production management, and healthcare operations.

Connecting business networks that handle production equipment and medical devices with general office systems. For cybersecurity measures in between, start with this.

- Connect factory monitoring IoT to the production control network to actively improve yield, enhance quality, and conduct condition monitoring. - By linking medical devices, electronic medical record systems, and medical administrative systems, let's work towards the ongoing efficiency of healthcare. However, there are often high barriers, and it is a natural flow to completely isolate "IoT-based devices due to security vulnerabilities." To reliably protect critical IT assets that are potentially at risk of external intrusion, they should remain completely independent from the outside while allowing information to be shared internally. That's where "OWCD" comes in. It physically shuts out signals from the outside, making it easy and straightforward to use without the need for configuration work. One-way communication control, which is recognized as a cyber resilience measure defined in Japan, the United States, and Europe, can be realized. A certain company's ransomware attack targeted network devices, right? Passwords can be breached. There are no settings for OWCD. It frees you from maintenance tasks such as configuring routers and firewalls, applying patches, and managing passwords. This technology is patented by Mitsubishi Heavy Industries, Ltd. There is an explanatory video at the related link below! Feel free to contact us.
