MSKD200-12

Overview

The Microsemi MSKD200-12 is a glass passivated rectifier diode module designed for high-power applications. It features a maximum repetitive reverse voltage (VRRM) of 1200 V and an average forward current (IFAV) rating of 200 A at a case temperature of 100°C. The module utilizes a D2 package with an isolated metal baseplate, providing a thermal resistance from junction to case of 0.21 °C/W per diode. It supports a non-repetitive peak surge current of 6800 A and operates within a junction temperature range of -40°C to 150°C.

Feature Summary

• Utilizes glass passivated chips for enhanced reliability
• Features heat transfer through an aluminum oxide ceramic isolated metal baseplate
• Provides electrical isolation via a 3000 Vrms insulation voltage

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 datasheets to confirm voltage ratings and configuration. Confirm that the component matches the required D2 package dimensions and mounting torque specifications. Check for RoHS compliance status as manufacturing standards may vary by production batch. Ensure proper handling procedures are followed due to the heavy module weight and fragile internal components.

Selection Notes

Select this module when a single-phase rectifier configuration is required with a 1200 V blocking capability. Evaluate the thermal management requirements based on the specified junction-to-case thermal resistance. Consider the physical constraints of the D2 package outline for heatsink integration. Verify that the operating current does not exceed the 200 A limit under the expected ambient conditions.

Part Context

This component belongs to the MSKD series of glass passivated rectifier diode modules manufactured by Microsemi Corporation. The series includes variants with different voltage ratings, such as 800 V, 1600 V, and 1800 V options. These modules share common packaging and thermal characteristics but differ in their maximum repetitive reverse voltage specifications.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify that any replacement part meets the same 1200 V rating and 200 A current capacity. Ensure the alternative device fits the D2 package footprint and maintains similar thermal performance metrics.
