The MacMic MM80FU040PC FRED diode datasheet provides specifications, ratings, and application information for the 400 V 80 A fast‑recovery diode.
The MM80FU040PC is a Fast Recovery Epitaxial Diode (FRED) designed for ultrafast recovery, low forward voltage, and high surge current capability. It is suitable for applications such as free‑wheeling, snubber, clamp circuits, inverter welders, PFC, plating power supplies, ultrasonic cleaners, converters, choppers, and UPS systems.
The datasheet lists absolute maximum ratings (400 V reverse voltage, 40 A average forward current, 156 W power dissipation), electrical characteristics (forward voltage 1.1 V at 40 A, reverse leakage up to 150 µA), thermal data (θJC 0.8 °C/W, junction temperature range –40 °C to +150 °C), and dynamic parameters such as reverse recovery time (22 ns typical). Package dimensions and a test circuit are also provided.
