Overview
The MUR620CT is a silicon ultrafast recovery rectifier manufactured by onsemi, housed in a TO-220AB package. It features a dual common cathode configuration with a maximum repetitive peak reverse voltage of 200 V and an average forward current rating of 8 A per diode. The device exhibits a typical forward voltage drop of 1.5 V at rated current and a maximum non-repetitive peak surge current capability of 100 A. Key electrical characteristics include a maximum reverse leakage current of 5 µA and a typical reverse recovery time of 35 ns. The component operates within a junction temperature range of -65 °C to +175 °C.
Feature Summary
- Ultrafast recovery characteristics enable efficient switching performance in high-frequency applications.
- Dual common cathode configuration integrates two independent rectifiers into a single package for space-saving designs.
- High thermal stability supports reliable operation across a wide operating temperature range up to 175 °C.
Applications
- High-frequency DC-to-DC converters
- Free-wheeling rectification in power supplies
- Polarity protection circuits
Procurement Notes
Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm pinout compatibility and packaging variations. Ensure that the selected variant matches the required thermal management specifications for the intended application environment. Cross-reference the part number with official distributor catalogs to confirm current availability status and compliance with relevant environmental directives such as RoHS.
Selection Notes
Select this component when designing circuits requiring fast switching speeds and moderate current handling capabilities. The TO-220AB package facilitates effective heat dissipation through board mounting or heatsink attachment. Consider the 200 V reverse voltage rating to ensure adequate margin for transient voltage spikes in the target power supply topology.
Part Context
This device belongs to the MUR series of ultrafast recovery rectifiers from onsemi. The series is engineered for general-purpose rectification in switch-mode power supplies where reduced reverse recovery charge minimizes switching losses. The MUR620CT specifically addresses applications needing robust current handling alongside rapid turn-off characteristics.
Replacement Considerations
Compatible substitutes include the MURD620CT and MURB620CT, which share identical electrical ratings but differ in package style. Verify pinout alignment before substitution to prevent circuit damage during installation.
