MUR840 Description

Short technical summary and product information.

The MUR840 is a fast recovery rectifier diode rated for 400V peak repetitive reverse voltage and 8A average rectified forward current. It offers a typical forward voltage of 1.3V at 8A and a reverse recovery time of 60ns (nominal). The device is designed for use in switching power supplies, inverters, and freewheeling diode applications.

 

Electrical characteristics include a peak repetitive forward current of 16A and a non-repetitive surge current rating of 100A. The operating junction temperature range spans -65°C to 175°C, with a junction-to-case thermal resistance of 2.0°C/W. The diode is ESD rated (Machine Model >400V, Human Body Model >16,000V) and meets UL 94 V-0 flammability.

 

The MUR840 is housed in a through-hole TO-220-2 (TO-220AC) package with epoxy molded case material, weighing approximately 1.9 grams. It is lead-free and RoHS compliant per the datasheet.
