Power Diodes

Diodes for power supply applications require low reverse recovery times and low forward voltage drops. Each discrete diode produced by Littelfuse boasts these characteristics, as well as low leakage. Our rectifier, ultrafast rectifier, fast recovery, and silicon Schottky diodes offer optimal switching solutions for dc–dc converters, induction heaters, and ultrasonic cleaners and welders. The Schottky devices are especially suited for use in EVs. Consult our Power Semiconductor Product Catalog to find the diode you require.
