MSKD100-16

Overview

The MSKD100-16 is a glass passivated rectifier diode module manufactured by Microsemi Corporation. It features a dual common cathode configuration with an average forward current rating of 50 A per diode and a maximum repetitive peak reverse voltage of 1600 V. The device utilizes a D1 base-mounted package for thermal management. Key electrical characteristics include a maximum RMS isolation voltage of 4000 V, a surge non-repetitive forward current capacity of 800 A, and a typical junction-to-case thermal resistance of 0.23 °C/W. Operating temperatures range from -55°C to +175°C.

Procurement Notes

Verify the specific suffix code against the manufacturer datasheet to confirm exact electrical tolerances and pinout compatibility. Confirm RoHS compliance status as legacy Microsemi products may have varying environmental declarations. Ensure the procurement source provides valid traceability documentation for high-reliability industrial applications.

Selection Notes

Select this component when designing circuits requiring high voltage blocking capabilities in a compact base-mount form factor. The dual common cathode arrangement simplifies layout for full-wave rectification compared to discrete assemblies. Evaluate thermal resistance requirements against the system's heat sink design to ensure junction temperature remains within the 175°C limit under continuous load conditions.

Part Context

This module belongs to the MSKD series of glass passivated rectifier diodes from Microsemi. The series offers various voltage ratings tailored for high-power industrial electronics. The MSKD100-16 specifically addresses the need for reliable high-voltage rectification in space-constrained power conversion modules where base mounting facilitates efficient thermal dissipation.

Replacement Considerations

Consult official Microsemi substitution guides for verified equivalents. Cross-reference parameters such as forward voltage drop, leakage current, and package dimensions with alternative manufacturers like Vishay or Littelfuse before implementation.
