Overview
The MUR3020PTG is a dual common cathode ultra-fast recovery rectifier manufactured by onsemi. It features a 200 V repetitive peak reverse voltage and a continuous forward current of 30 A per diode. The device utilizes heatsink mounting in a TO-247AC package. Key electrical characteristics include a maximum reverse recovery time of 50 ns and a peak forward voltage of 1.1 V at rated current. It supports a non-repetitive surge current of 325 A and operates within a junction temperature range of -65 °C to +175 °C.
Feature Summary
- Dual common cathode configuration for half-bridge applications
- Ultra-fast recovery characteristics with minimal switching losses
- Heatsink-mounted construction for efficient thermal management
- High surge current capability for robust circuit protection
Applications
- High-frequency DC-DC converters
- Free-wheeling rectification in power supplies
- Inverter circuits
- Motor drive systems
Procurement Notes
Verify the specific suffix 'PTG' against the official onsemi datasheet to confirm pinout, packaging, and compliance details. Ensure the component matches the required thermal resistance and mechanical dimensions for your heatsink interface. Confirm availability status as manufacturing transitions may affect supply continuity.
Selection Notes
Select this component when designing circuits requiring fast switching speeds and high current handling in a through-hole package. Compare the 50 ns reverse recovery time against standard recovery alternatives to ensure reduced electromagnetic interference. Verify that the 200 V rating provides sufficient margin for your specific bus voltage and transient conditions.
Part Context
This part belongs to the MUR series of ultra-fast recovery rectifiers from onsemi. It is designed for high-efficiency power conversion applications where low reverse recovery charge is critical. The TO-247AC package allows for direct mounting to heat sinks, facilitating thermal dissipation in high-power density designs.
Replacement Considerations
Check for equivalents such as MUR3020CT or MUR3020PT from other manufacturers. Ensure replacement parts match the 30 A current rating, 200 V voltage rating, and 50 ns recovery time. Verify package compatibility and thermal performance specifications before substitution.
