MSKD60-12

Overview

The MSKD60-12 is a glass passivated rectifier diode module from the Microsemi MSK/MSA/MSC D60 series. It features a maximum repetitive reverse voltage (VRRM) of 1200 V and a surge peak forward voltage (VRSM) of 1300 V. The average forward current (IFAV) is rated at 60 A under single-phase half-wave conduction conditions with a case temperature of 100°C. The non-repetitive peak forward surge current (IFSM) reaches 1150 A for a duration of 10 ms. The module utilizes a D1 package with an aluminum oxide DBC ceramic isolated metal baseplate.

Feature Summary

• Utilizes glass passivated chips for enhanced reliability
• Features heat transfer through an aluminum oxide DBC ceramic isolated metal baseplate
• Includes UL E243882 approval

Applications

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

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm that the part number suffix matches the required voltage rating, as the MSKD60-12 specifically denotes the 1200V variant within the broader MSKD60 family. Ensure thermal interface materials are compatible with the D1 package mounting requirements to maintain specified thermal resistance values during operation.

Selection Notes

Select this module when a 1200V blocking capability is required alongside a 60A continuous current rating in a D1 footprint. Consider the 0.59 °C/W junction-to-case thermal resistance for heatsink design calculations. Verify that the operating junction temperature remains within the -40°C to +150°C range and that the mechanical torque specifications for M5 and M6 terminals are strictly adhered to during installation.

Part Context

This component belongs to the MSK/MSA/MSC D60 series of glass passivated rectifier diode modules manufactured by Microsemi Corporation. The series offers various voltage ratings ranging from 800V to 1800V, sharing common physical dimensions and thermal characteristics while differing in electrical breakdown limits. The MSKD60-12 specifically represents the 1200V configuration within this standardized product line.

Replacement Considerations

Direct substitutes include other MSKD60-12 units or equivalent modules from the same MSK/MSA/MSC D60 family with matching 1200V ratings. Cross-brand replacements must match the 60A current rating, 1200V VRRM, D1 package outline, and thermal resistance specifications to ensure compatibility with existing cooling systems and mounting hardware.
