MSAD200-12

Overview

The Microsemi MSAD200-12 is a glass-passivated rectifier diode module designed for high-power applications. It features a maximum repetitive reverse voltage of 1200V and an average forward current rating of 200A at a case temperature of 100°C. The device utilizes a D2 package with an isolated metal baseplate for efficient heat transfer through aluminum oxide ceramic insulation. Key electrical characteristics include a forward voltage of 1.3V at 300A and a non-repetitive surge current capability of 6800A.

Feature Summary

• Glass passivation provides enhanced stability and protection against environmental stressors.
• Aluminum oxide ceramic isolation on the metal baseplate ensures effective thermal management and electrical safety.
• Robust construction supports high surge currents and wide operating temperature ranges.

Applications

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

Procurement Notes

Verify the specific suffix to confirm the 1200V rating, as the MSAD200 series includes variants with different blocking voltages. Confirm that the D2 package outline matches your mechanical constraints. Check for RoHS compliance status if required by your manufacturing standards. Ensure proper torque specifications are applied to M6 terminals during installation.

Selection Notes

Select this module when a single-phase configuration with high current capacity is required. Compare thermal resistance values against your heatsink design to ensure junction temperatures remain within limits. Consider the 1200V rating relative to peak line voltages in your application to maintain adequate safety margins.

Part Context

This component belongs to the MSAD200 family of glass-passivated rectifier modules from Microsemi.
