MacMic Fast Recovery Diode Distributor | FRED Modules
Genuine MacMic fast recovery diode modules with fast, soft recovery for PFC, freewheeling and high-speed rectification.
MacMic FRD Modules Overview
BeiLuo supplies genuine MacMic fast recovery epitaxial diode (FRED) modules, made with MacMic's own FRED chip for fast and soft recovery in high-speed switching circuits. MacMic was among the earliest Chinese companies to develop high-power FRED chips, and the modules deliver a strong price-performance balance for PFC stages, freewheeling paths and high-speed rectification. The module line offers both low-cost non-isolated packages and full-isolated packages, with several internal circuit configurations to match different topologies. Because the diode is optimized for fast, soft recovery, it reduces reverse-recovery loss and EMI in hard-switched converters, which is exactly where ordinary rectifiers struggle. As an authorized MacMic distributor, BeiLuo ships every FRD module with import declaration, certificate of origin and RoHS documentation, and supports design-in with an in-house FAE team. Our engineers help you match VRRM and IF(AV) to your current, estimate recovery loss, and pair the diode with the right IGBT or MOSFET switch. In-stock mainstream ratings and long-term availability keep PFC and inverter production supplied reliably. Selecting an FRD module means matching VRRM, IF(AV) and recovery charge to your converter and then choosing isolated or non-isolated packaging. BeiLuo engineers help you compare recovery behavior, pair the diode with a matched switch and confirm the thermal design before you commit, keeping EMI and loss under control.

Frequently Asked Questions
How do I read the FRD module table?
Match VRRM to your reverse voltage with margin, then use IF(AV) for current capability. Configuration describes the internal diode arrangement and Package tells you isolated or non-isolated.
Pick voltage and current first, then confirm isolation needs.
Why does soft recovery matter in my converter?
Soft recovery limits the current snap at turn-off, which reduces reverse-recovery loss, voltage overshoot and EMI. That often removes snubbers and simplifies EMC.
It matters most in hard-switched PFC and inverter stages.
Isolated or non-isolated package: which do I need?
Choose an isolated package when the module mounts directly to a common heatsink and you need insulation; choose a non-isolated package for lower cost when your thermal design already isolates.
Confirm creepage and clearance for your voltage class.
How do I pair an FRD with an IGBT?
Match the diode's IF(AV) and recovery charge to the IGBT current and switching frequency so the freewheeling path does not dominate losses. A fast IGBT deserves a fast diode.
Our FAE team can recommend a matched pair.
