Designed for high-frequency switching power supplies, fast-charging adapters, high-frequency inverters, telecom power modules. The Schottky type features low forward voltage drop for low-voltage high-current rectification with less heat and higher efficiency; the fast-recovery type offers short reverse recovery time for high-frequency PWM switching circuits, such as fast chargers, SMPS main rectification and high-frequency inverter auxiliary power. This model is rated 3A / 200V, a medium-low power class device suitable for low-voltage circuits.
