MSKD120-12

Overview

The MSKD120-12 is a glass-passivated rectifier diode module with a maximum repetitive reverse voltage of 1200 V and an average forward current rating of 120 A at a case temperature of 100°C. It features a single-diode configuration in the D1 package, utilizing an aluminum oxide ceramic isolated metal baseplate for heat transfer. The module exhibits a typical forward voltage of 1.43 V at 300 A and a junction-to-case thermal resistance of 0.26 °C/W per diode.

Feature Summary

Glass passivation provides chip protection
Aluminum oxide ceramic isolation on metal baseplate enables efficient heat transfer

Applications

Non-controllable rectifiers for AC/AC converters
Line rectifiers for transistorized AC motor controllers
Field supply for DC motors

Procurement Notes

Verify the specific suffix against official Microsemi documentation to confirm exact electrical ratings and mechanical dimensions. Confirm availability status as older series may be discontinued. Ensure mounting torque specifications are strictly followed during installation to maintain thermal performance and reliability.

Selection Notes

Select this component for high-voltage rectification applications requiring robust surge capability and reliable thermal management. Evaluate the 1200 V blocking voltage against system peak reverse voltages. Consider the D1 package form factor for compatibility with existing heatsink infrastructure and mounting constraints.

Part Context

This part belongs to the MSK/MSC/MSA D120 family of glass-passivated rectifier modules. These components share common mechanical outlines and thermal characteristics while varying in voltage ratings. The MSKD variant specifically denotes the 1200 V blocking voltage option within this standardized industrial power diode lineup.

Replacement Considerations

Consult official Microsemi substitution guides for verified equivalents. Cross-reference voltage, current, and thermal parameters carefully when considering alternative manufacturers.
