Procurement Notes

Verify the specific part number suffix against official documentation to confirm voltage ratings, as variants exist within the series. Confirm compliance requirements such as RoHS status directly with the manufacturer or authorized distributors before procurement. Ensure that thermal interface materials and mounting hardware meet the specified torque values to maintain reliable operation and proper heat dissipation during installation.

Selection Notes

Select this component when high-speed switching performance and isolation are required in power conversion circuits. The 1200 V rating suits medium-voltage applications, while the 200 A current capacity supports substantial load demands. Evaluate thermal impedance and cooling requirements to ensure the junction temperature remains within the specified operational limits under continuous and surge loading conditions.

Part Context

This module belongs to the FRS series of fast recovery diodes manufactured by SanRex Corporation. The series is engineered for discrete semiconductor modules used in power electronics. The FRS200CA120 variant specifically addresses the need for high voltage blocking capabilities combined with rapid recovery characteristics, distinguishing it from standard rectifier modules in terms of switching speed and efficiency.

Replacement Considerations

Consult official datasheets for cross-reference information. Verify that any substitute component matches the 1200 V reverse voltage, 200 A current rating, and 350 ns reverse recovery time specifications. Ensure physical dimensions, terminal configurations, and isolation voltage ratings are compatible with the existing circuit board layout and mounting constraints.
