Overview
The MSCD120-12 is a glass passivated rectifier diode module from the MSxD120 series, manufactured by Microsemi Corporation. It features a maximum repetitive reverse voltage (VRRM) of 1200 V and a surge peak repetitive reverse voltage (VRSM) of 1300 V. The module provides an average forward current (IFAV) rating of 120 A at a case temperature of 100°C. It utilizes a D1 package with an aluminum oxide ceramic isolated metal baseplate for heat transfer. Key electrical characteristics include a forward voltage of 1.43 V at 300 A and a maximum reverse leakage current of 6 mA at 1200 V.
Feature Summary
- Glass passivated chip construction
- Heat transfer through aluminum oxide ceramic isolated metal baseplate
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 against official Microsemi documentation. Confirm that the specific part number matches the required voltage and current ratings for your application. Check for any product change notices or end-of-life announcements prior to procurement. Ensure thermal management solutions are compatible with the specified mounting torque requirements.
Selection Notes
Select this module based on its 1200 V blocking capability and 120 A continuous current rating. Consider the thermal resistance values for heatsink design. Verify compatibility with the D1 package outline dimensions. Evaluate the operating junction temperature range relative to system constraints.
Part Context
This component belongs to the MSKD120, MSAD120, and MSCD120 family of glass passivated rectifier diode modules. These modules share similar mechanical and thermal characteristics but differ in voltage ratings. The MSCD120 variant specifically addresses applications requiring 1200 V blocking voltage.
Replacement Considerations
Consult official Microsemi documentation for verified substitute part numbers. Cross-reference voltage and current ratings carefully when considering alternatives.
