MURH840CTG

Overview

The onsemi MURH840CTG is an ultrafast recovery rectifier featuring a dual common cathode configuration housed in a TO-220AB package. It supports a maximum repetitive peak reverse voltage of 400 V and an average forward current of 4 A per diode. The device exhibits a maximum forward voltage of 2.2 V and a peak reverse recovery time of 28 ns. It withstands a non-repetitive peak forward surge current of 100 A and operates within a junction temperature range from -65°C to +175°C.

Feature Summary

Dual common cathode architecture for efficient bridge or center-tapped circuit implementation
Ultrafast recovery characteristics minimize switching losses and electromagnetic interference
Robust thermal management capabilities enabled by the TO-220AB through-hole package

Applications

High-frequency DC-to-DC converters
Free-wheeling rectification in power supplies
Polarity protection circuits

Procurement Notes

Verify the complete part number including the suffix against official manufacturer documentation to ensure correct specifications. Confirm that the component meets required automotive or industrial standards if applicable. Check datasheet revisions for any updates to electrical limits or mechanical dimensions before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits requiring fast switching speeds and high voltage blocking capability in a dual configuration. The TO-220AB package facilitates easy mounting on heat sinks for thermal dissipation. Ensure the application current does not exceed the 4 A rating per diode under all operating conditions.

Part Context

This device belongs to the MURH8 series of ultrafast recovery rectifiers from onsemi. The series is engineered for high-efficiency power conversion applications where rapid turn-off times are critical. The MURH840CTG specifically targets designs needing 400 V isolation with moderate current handling in a standard through-hole form factor.
