MF200K04F4N-BP

Overview

The MF200K04F4N-BP is a silicon Fast Recovery Epitaxial Diode (FRED) module manufactured by Micro Commercial Components. It features a single diode configuration with a maximum repetitive reverse voltage of 400 V and an average forward current rating of 200 A per module at a case temperature of 125°C. The device exhibits a typical forward voltage drop of 1.1 V at 100 A and supports high surge currents up to 1800 A for half-cycle sine waves at 60 Hz. Thermal resistance from junction to case is specified at 0.11 °C/W per module, with a recommended mounting torque of 3 to 4.7 N·m for M6 screws.

Procurement Notes

Verify the specific F4N suffix against official MCC documentation to confirm pinout and dimensional compatibility. Confirm RoHS compliance status as indicated by the BP suffix. Ensure thermal management solutions align with the 0.11 °C/W junction-to-case thermal resistance specification. Validate that application voltages remain within the 400 V repetitive peak reverse voltage limit.

Selection Notes

Select this component for applications requiring high current handling with controlled reverse recovery behavior. The 200 A continuous current rating suits heavy-duty industrial power conversion. Consider the 400 V blocking capability when designing circuits with potential voltage spikes. Evaluate the screw-mount installation requirements against available mechanical space and thermal interface materials.

Part Context

This discrete semiconductor module belongs to the MF200K series of fast recovery diodes from Micro Commercial Components. It utilizes silicon technology optimized for high-power switching environments. The module format allows for direct integration into busbar systems or heat sink assemblies common in industrial power electronics.

Replacement Considerations

Consult official MCC substitution guides for verified equivalents. Cross-reference electrical parameters such as reverse recovery time and forward voltage drop carefully. Verify mechanical dimensions and mounting hole patterns to ensure physical compatibility without redesigning the PCB or chassis.
