Schottky Barrier Diodes Optimised for Vehicle Front Lighting

18 February 2024

Possessing a 100V breakdown voltage, ROHM’s YQ series of Schottky barrier diodes can be used in a multitude of power system and protection circuitry implementations.

These devices feature the company’s proprietary trench MOS structure that enables a simultaneously reduction in both the VF and IR figures - 7% and 82%, respectively, compared to conventional planar type equivalents. They exhibit a 15ns reverse recovery time (trr), meaning that that trr losses are lowered by around 37%. Key YQ series applications include the drive circuits for solid-state automobile headlights, the DC/DC converters found in electric vehicle (EV) powertrains and industrial power supplies.
