Overview
The MSRD620CTG is a Switch-mode Soft Ultrafast Recovery Power Rectifier manufactured by onsemi in a plastic DPAK package. It features a peak repetitive reverse voltage of 200 V and an average rectified forward current of 6.0 A per package (3.0 A per leg). The device exhibits a maximum instantaneous forward voltage of 1.35 V at TJ = 150 °C and a maximum reverse recovery time of 55 ns. It supports a non-repetitive peak surge current of 50 A and operates within a junction temperature range of -55 to +175 °C.
Feature Summary
- Soft ultrafast recovery characteristics with typical 35 ns recovery time for high-frequency switching applications
- Matched dual die construction allowing paralleling for increased current output
- Highly stable oxide passivated junction ensuring reliability under stress
- Short heat sink tab manufactured rather than sheared for improved thermal performance
Applications
- Low voltage, high frequency switching power supplies
- Free wheeling diodes
- Polarity protection diodes
Procurement Notes
Verify the specific ordering suffix when sourcing components. The datasheet indicates that the MSRD620CTG part number was removed from the document in Revision 11 dated December 16, 2025. Confirm availability and equivalent part numbers such as MSRD620CTT4G or NRVSRD620VCTT4G with the manufacturer or authorized distributors to ensure compliance with current production status.
Selection Notes
Select this component for circuits requiring soft ultrafast recovery behavior to minimize switching losses and electromagnetic interference. Ensure the design accommodates the 200 V reverse voltage rating and the 6.0 A total forward current capability. Consider the thermal resistance values provided for both junction-to-case and junction-to-ambient configurations when designing the heat dissipation strategy for the DPAK package.
Part Context
This device belongs to the MSRD6 series of switch-mode power rectifiers produced by onsemi. It utilizes state-of-the-art geometry featuring epitaxial construction, glass passivation, and metal overlay contact. The product line includes variants like the NRVSRD620VCT which may carry prefixes for automotive applications requiring unique site and control change requirements, indicating potential qualification for AEC-Q101 standards.
Replacement Considerations
The MSRD620CTT4G is listed as a direct alternative in the same DPAK package. The NRVSRD620VCTT4G serves as another variant within the family. Verify pinout compatibility and electrical specifications against the original design requirements before substitution.
