MMF200S120DK
1200 V MacMic fast recovery diode module, dual diode, 2 x 200 A, with soft recovery for PFC and freewheeling.
The MMF200S120DK is a 1200 V MacMic fast recovery diode module with a nominal average forward current of 2 x 200 A in a dual-diode configuration. It is made with MacMic's own FRED chip, which delivers fast and soft recovery that limits reverse-recovery loss, voltage overshoot and EMI in hard-switched converters. The non-isolated package keeps cost low where the thermal design already provides the required insulation, and the dual-diode arrangement suits freewheeling, rectification and PFC stages. Soft recovery is especially valuable in PFC and inverter circuits, where an ordinary rectifier would generate excessive noise and require snubbers. Every module is factory-traceable and ships with import declaration, certificate of origin and RoHS documentation. Designers should match the diode's recovery charge to the paired switch and confirm current sharing between the two diodes, and our FAE team can recommend a matched IGBT or MOSFET for the stage. BeiLuo holds this diode in regional stock and supplies it with import, origin and RoHS documentation, keeping the supply chain audit-ready for customs and quality reviews.
FAE Professional Review
The MMF200S120DK is the diode we pair with 1200 V IGBT stages when EMI and recovery loss matter. The soft recovery keeps overshoot low in hard-switched PFC and freewheeling paths, and 2 x 200 A covers high-current modules comfortably.

Frequently Asked Questions
Why does soft recovery matter for this module?
Soft recovery limits the current snap at turn-off, cutting reverse-recovery loss, overshoot and EMI. In PFC and inverter stages that often removes snubbers and simplifies EMC.
Fast, soft diodes are essential in hard-switched converters.
Non-isolated or isolated: which do I choose?
Choose the non-isolated MMF200S120DK when your thermal design already insulates; choose the isolated MMF200N120DK6B when the module mounts to a common heatsink and needs insulation.
Confirm creepage and clearance for 1200 V.
How do I pair this diode with a switch?
Match the diode's IF(AV) and recovery charge to the switch current and frequency so the freewheeling path does not dominate losses. A fast IGBT deserves a fast diode.
Our FAE team can recommend a matched pair.
Is the module stocked and documented?
