MURH840CTH

Overview

The onsemi MURH840CTH 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 a continuous forward current of 4 A per diode leg. The device exhibits a typical reverse recovery time of 28 ns and a maximum forward voltage drop of 2.2 V at rated current. 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

Ultrafast recovery characteristics enable high-frequency switching with minimal reverse recovery losses.
Dual common cathode architecture allows for efficient bridge or center-tapped circuit implementations.
Plastic encapsulation meets UL 94 V-0 flammability ratings for enhanced safety compliance.

Applications

High-frequency switched-mode power supplies
Free-wheeling rectification in inverter circuits
Polarity protection applications

Procurement Notes

Verify the specific suffix 'H' against official datasheets, as it may denote tape-and-reel packaging rather than tube. Confirm RoHS compliance status and lead finish specifications directly with the manufacturer or authorized distributors prior to ordering to ensure alignment with assembly requirements.

Selection Notes

Select this component when designing circuits requiring fast switching speeds and moderate current handling in a through-hole format. Ensure the thermal management design accommodates the 175°C maximum junction temperature rating. Compare total power dissipation against alternative packages if space constraints are critical.

Part Context

This part belongs to the MURH8 Series of ultrafast recovery rectifiers from onsemi. These devices utilize advanced silicon technology to achieve superior switching performance compared to standard recovery diodes. The series is engineered for high efficiency in power conversion systems where rapid turn-off times are essential.
