RURD810

Overview

The RURD810 is a single-element, one-phase silicon rectifier diode manufactured by Harris Corporation. It features an avalanche capability and is designed for hyperfast soft recovery applications. The device is housed in a leaded package with the cathode connected to the case. Key electrical parameters include a maximum repetitive reverse voltage of 1000V, an average forward current rating of 8A, and a maximum non-repetitive peak forward surge current of 100A. The component supports a maximum operating temperature of 175°C and exhibits a maximum forward voltage of 3.2V.

Feature Summary

• Avalanche rated for robust operation under transient conditions
• Hyperfast soft recovery characteristics for efficient switching
• Case-connected cathode for simplified thermal management

Applications

• High-frequency power supply circuits
• Inductive load freewheeling paths
• General purpose rectification in industrial electronics

Procurement Notes

Verify the specific manufacturer source, as Harris Corporation's semiconductor assets have undergone corporate restructuring and acquisition. Confirm that the component meets current environmental compliance standards, as original documentation may indicate non-RoHS status. Ensure the package marking and pinout align with the R-PSFM-T2 specification before integration into production designs.

Selection Notes

Select this component when high-speed recovery and avalanche ruggedness are required in a compact form factor. The 8A current rating and 1000V blocking voltage suit medium-power DC-DC converters and motor drive circuits. Consider the case-mounted cathode for effective heat dissipation strategies in space-constrained assemblies requiring reliable performance at elevated temperatures.

Part Context

This part belongs to the Harris rectifier diode family, specifically engineered for high-speed switching applications. The RURD series utilizes advanced silicon planar technology to achieve fast recovery times while maintaining high surge current capabilities. These components are typically used in demanding power electronic environments where reliability and speed are critical design factors.
