Overview
The MSRD620CT is a soft ultrafast recovery power rectifier manufactured by onsemi in a plastic DPAK package. It features a matched dual common cathode configuration with an average rectified forward current of 6.0 A per package and 3.0 A per leg at a case temperature of 137 °C. The device supports a peak repetitive reverse voltage of 200 V and a non-repetitive peak surge current of 50 A. Electrical characteristics include a maximum instantaneous forward voltage of 1.35 V at 6.0 A and a maximum reverse recovery time of 55 ns.
Feature Summary
- Soft Ultrafast Recovery technology for high-frequency switching applications
- Matched dual die construction allowing parallel connection for higher current output
- Highly stable oxide passivated junction for reliability
- Short heat sink tab manufactured without shearing
Applications
- Low voltage, high frequency switching power supplies
- Free wheeling diodes
- Polarity protection diodes
Procurement Notes
Verify the specific ordering suffix to ensure correct packaging and automotive qualification status. The base part number corresponds to the standard DPAK package. Confirm RoHS compliance and Pb-free status as indicated in the datasheet. Check for prefix variations such as NRVSRD or SSRD8 if unique site control or AEC-Q101 qualification is required for the target application.
Selection Notes
Select this component for circuits requiring fast recovery times and low reverse recovery charge. Ensure thermal management accounts for the junction-to-case thermal resistance of 9.0 °C/W per leg. Verify that the operating case temperature does not exceed limits when derating the forward current. Consider the 200 V reverse voltage rating relative to the circuit's peak inverse voltage requirements.
Part Context
This device belongs to the MSRD6 series of switch-mode soft ultrafast recovery power rectifiers. It utilizes epitaxial construction with glass passivation and metal overlay contacts. The component is designed to replace older generation rectifiers in modern power supply designs where efficiency and switching speed are critical performance factors.
Replacement Considerations
The datasheet lists NRVSRD620VCT as a related variant. Prefixes NRVSRD and SSRD8 indicate versions qualified for automotive applications under AEC-Q101 standards with PPAP capability. Verify pinout compatibility and thermal characteristics before substituting.
