RURD3020

Overview

The RURD3020 is a single-element, one-phase silicon rectifier diode manufactured by Harris Corporation. It features an avalanche capability and is housed in a TO-251 package with two pins. The device supports a maximum average forward current of 4A and a repetitive peak reverse voltage of 600V. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 40A and a maximum forward voltage of 1.5V. It operates within a temperature range of -55°C to 175°C.

Feature Summary

• Avalanche rated for robust performance under transient conditions
• Ultra-fast soft recovery design for high-speed switching applications
• Single element configuration in a compact surface-mount package

Applications

• High-frequency rectification circuits
• Free-wheeling diode applications
• Ultra-fast soft recovery requirements

Procurement Notes

Verify the specific manufacturer source, as Harris Corporation's semiconductor assets have undergone corporate transitions. Confirm RoHS compliance status and exact package marking against the original datasheet specifications. Ensure the component matches the TO-251 form factor and electrical ratings required for the target circuit design before procurement.

Selection Notes

Select this component for designs requiring ultra-fast recovery characteristics and avalanche ruggedness. The TO-251 package suits space-constrained surface-mount layouts. Verify that the 4A average current and 600V reverse voltage ratings exceed the circuit's operational demands. Consider thermal management capabilities given the 175°C maximum junction temperature rating.
