MSKD70-12

Overview

The MSKD70-12 is a glass-passivated rectifier diode module with a maximum repetitive reverse voltage of 1200 V and an average forward current rating of 70 A. It features a single-phase half-wave configuration with a peak non-repetitive surge current of 1400 A at 10 ms. The module utilizes an aluminum oxide DBC ceramic isolated metal baseplate for heat transfer, providing a thermal resistance from junction to case of 0.51 °C/W per diode. Operating temperatures range from -40°C to 150°C.

Feature Summary

Glass passivated chip construction
Heat transfer through aluminum oxide DBC ceramic isolated metal baseplate
UL E243882 approved

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 manufacturer documentation for the MSKD70-12 part number to confirm current availability status and any potential obsolescence notices. Ensure that the required electrical parameters, such as the 1200 V blocking voltage and 70 A current rating, align precisely with the design specifications before procurement. Cross-reference the D1 package outline dimensions to guarantee mechanical compatibility with existing heatsink and mounting infrastructure.

Selection Notes

Select this component when designing circuits requiring robust single-phase rectification with high surge current capability. The 1200 V rating suits applications involving higher voltage AC lines. Consider the thermal management requirements associated with the 0.51 °C/W junction-to-case resistance. Verify that the operating temperature range meets the environmental conditions of the intended installation site.

Part Context

This module belongs to the MSK series of glass-passivated rectifier diodes manufactured by Microsemi Corporation. The series includes variants with different voltage ratings, such as MSCD70 and MSAD70. The MSKD70-12 specifically denotes the 1200 V version within this family, designed for industrial power conversion applications requiring reliable performance under high thermal stress.
