Ultra-low-capacity photodiode

No need for electromagnetic shielding outside! Successfully reduced the capacity of the photodiode to less than a fraction and achieved wideband expansion.

The light-receiving system experiences a decrease in sensitivity when broadened in bandwidth, and high-sensitivity light-receiving ICs have the issue of being easily affected by external noise. We have successfully developed a new type of light-receiving element that addresses these challenges, resulting in a light-receiving IC that is both broadband and high-sensitivity while being less susceptible to external noise. Our new photodiode achieves broadband capability through an ultra-low capacitance that is less than a fraction of the limits of conventional technology, thanks to its unique structure. It can incorporate a shielding effect internally, eliminating the need for external electromagnetic shielding. 【Features】 ■ High sensitivity in a broad bandwidth ■ Parasitic capacitance is less than a fraction compared to conventional photodiodes ■ Light-receiving element unaffected by external noise *For more details, please refer to the PDF document or feel free to contact us.

High current bidirectional TVS diode 'PTVS1-240C-M'

Bidirectional high pulses of both positive and negative voltages can be absorbed! Surface mount package that does not take up implementation area.

The "PTVS1-240C-M" is a high-current bidirectional TVS diode rated for a stand-off voltage of 240V, providing bidirectional port protection. It is designed for use in high-power DC bus applications that require a current surge tolerance of 1kA (8/20μs). Compared to typical low-voltage clamp TVS diodes, it allows for a reduction in component count. The temperature coefficient is typically 0.1%/°C, resulting in a stable breakdown voltage with respect to temperature. 【Features】 ■ 1kA (@8/20us) current tolerance ■ Breakdown voltage and clamp voltage are nearly identical ■ Surge current tolerance has a temperature derating of about 75% ■ Can absorb high pulses of both positive and negative voltages bidirectionally ■ Surface mount package that does not take up much mounting area *For more details, please download the PDF (English version) or feel free to contact us.

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.
