RU 4C

Single Diodes Overview

The RU4C is a silicon mesa-type diode manufactured by Sanken Electric. It features a peak reverse voltage of 1000 V and an average forward current rating of 1.5 A without a heatsink, or 2.5 A with a fin. The device has a maximum forward voltage drop of 1.60 V at 3.0 A. Reverse recovery times are specified as 0.4 µs at the 90% recovery point and 0.18 µs at the 75% point. Thermal resistance from junction to lead is 8 °C/W. Operating and storage temperatures range from -40°C to +150°C.

Single Diodes Feature Summary

Single Diodes Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm lot markings match the red type number and date code format described in the datasheet. Check for physical defects such as stains, rust, or flaws on the resin molded body. Ensure compliance with RoHS standards if required by the application specifications.

Single Diodes Selection Notes

Select this component for applications requiring high voltage isolation and fast switching speeds. Consider thermal management strategies based on ambient temperature conditions, as current derating is necessary above 40°C without a heatsink. Verify that the package dimensions and lead wire specifications fit the target PCB layout constraints.

Single Diodes Part Context
