The MSRT100140AD is a silicon standard recovery diode module from the MSRTA series, rated for a repetitive peak reverse voltage of 1400 V and an average forward current of 100 A per leg. It utilizes a three-tower isolated package with an electrically isolated base plate. The maximum instantaneous forward voltage is 1.1 V at 100 A, while the thermal resistance from junction to case is 0.45 °C/W. Operating temperatures range from -55 °C to +150 °C.
Verify the specific voltage rating suffix (140) against the application requirements, as the datasheet covers a range from 1200 V to 1600 V. Confirm that the screw-mount terminal configuration matches the mechanical assembly. Ensure thermal interface materials are compatible with the specified junction-to-case thermal resistance for proper heat dissipation.
Select this component when a 1400 V blocking voltage is required alongside 100 A continuous current handling. The isolated base plate makes it suitable for applications requiring galvanic isolation between the circuit ground and the heatsink. Consider the standard recovery characteristics for general-purpose switching frequencies rather than high-speed applications.
This part belongs to the MSRT100XXXD family, which includes variants with voltages from 1200 V to 1600 V. The 'A' suffix typically denotes specific electrical tolerances or packaging variations within the GeneSiC/Navitas portfolio. These modules are designed for robust industrial environments requiring high reliability and thermal performance.
Direct substitutes include other MSRT100140AD units from the same manufacturer. Cross-brand replacements must match the 1400 V rating, 100 A current, and three-tower isolated package dimensions. Verify thermal resistance and forward voltage specifications to ensure equivalent performance in the target circuit.
