SiC Schottky Barrier Diode "ICS Series"

SiC Schottky Barrier Diode "ICS Series"

Contributes to the high efficiency of power supplies through high current, high voltage characteristics, and fast recovery characteristics of SiC.

Our ICS series consists of Schottky barrier diodes made from SiC. By using SiC as the material, we achieve high current and high voltage characteristics that were not possible with silicon, while also maintaining the fast recovery characteristics of Schottky barrier diodes. By using them in power supply circuits for PFC (power factor correction circuits) and as freewheeling diodes in inverter circuits, we contribute to improving power supply efficiency and reducing excess power consumption during switching. Compared to fast recovery diodes known for their high-speed recovery characteristics, our products have achieved a 33.6% increase in efficiency and a 48.2% reduction in losses. Additionally, beyond improving power supply efficiency, our SiC Schottky barrier diodes offer advantages such as operation in high-temperature environments exceeding silicon and longer lifespan, so we encourage you to try our SiC Schottky barrier diodes.

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.
