MSKD100-12

Overview

The MSKD100-12 is a glass passivated rectifier diode module manufactured by Microsemi Corporation. It features a single pair of common anode configuration with a maximum DC reverse voltage of 1200 V and an average rectified current of 100 A per diode. The forward voltage is specified at 1.9 V when tested at 300 A. The device utilizes standard recovery technology with a reverse recovery time exceeding 500 ns. It is designed for base mounting in the D1 package format.

Feature Summary

• Glass passivation provides enhanced protection against environmental stressors and mechanical damage to the semiconductor junctions.
• Common anode dual-diode architecture simplifies circuit design for specific power conversion topologies requiring paired switching elements.
• Standard recovery characteristics are optimized for general-purpose high-voltage rectification applications where ultra-fast switching is not required.

Applications

• Industrial motor drives
• High voltage power supplies
• Inverter circuits

Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence notices. Confirm that the D1 package dimensions match the intended thermal management and mechanical mounting requirements. Ensure that the 1200 V rating aligns with the peak inverse voltage stresses present in the target application circuit to prevent premature failure.

Selection Notes

Select this module when a robust, high-voltage solution with moderate switching speeds is required. The 1200 V rating accommodates line voltages up to approximately 600-690 V AC systems. Consider the thermal resistance of the base mount interface for heat dissipation. Compare against faster recovery alternatives if switching losses become critical in high-frequency operation scenarios.

Part Context

This component belongs to the MSKD series of glass passivated rectifier modules from Microsemi. These modules are engineered for durability in harsh industrial environments. The series typically includes variants with different voltage ratings such as 800 V and 1600 V options, maintaining consistent current handling capabilities across the family for standardized design integration.

Replacement Considerations

Public confirmed substitute part numbers were not identified in the provided documentation. Verify compatibility with direct replacements by matching the 1200 V reverse voltage, 100 A current rating, D1 package footprint, and common anode configuration.
