RURD3015

Overview

The RURD3015 is a silicon rectifier diode manufactured by Harris Corporation. It features an avalanche capability and is designed for ultrafast soft recovery applications with a reverse recovery time of less than 35 nanoseconds. The device operates in a single-phase, single-element configuration within a TO-251 package. Key electrical parameters include a maximum average forward current of 3 amperes and a repetitive peak reverse voltage rating of 150 volts. The component supports a junction temperature up to 175°C and exhibits a maximum non-repetitive peak forward surge current of 30 amperes.

Feature Summary

• Ultrafast soft recovery characteristics suitable for high-frequency switching
• Avalanche energy rated for robust operation under transient conditions
• Planar silicon nitride passivated ion-implanted epitaxial construction

Applications

• High-frequency power supply circuits
• Free-wheeling diode applications in inductive loads
• Snubber circuits requiring fast recovery times

Procurement Notes

Verify the manufacturer source carefully as Harris Corporation's semiconductor division has undergone acquisitions. Confirm the specific datasheet revision matches your design requirements. Check for RoHS compliance status as older Harris components may not meet current environmental standards. Ensure the TO-251 package footprint aligns with your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when low reverse recovery charge is critical for minimizing switching losses. The 150V rating suits low-voltage DC-DC converters. Compare thermal resistance values against your heat dissipation capabilities. Consider the TO-251 package size relative to available board space. Verify that the 3A current rating meets the continuous load requirements of the target circuit application.

Part Context

This part belongs to the Harris ultrafast recovery rectifier product line, which includes similar devices like the MUR series and RURP series. These components were widely used in consumer electronics and industrial power supplies during the era of Harris Semiconductor manufacturing. The technology represents an evolution from standard recovery diodes to faster switching alternatives for improved efficiency.

Replacement Considerations

Equivalent parts include the MUR3015PT or RURH1515CC from Intersil or Fairchild Semiconductor. Verify pinout compatibility and thermal performance before substitution. Ensure the replacement device maintains the same ultrafast recovery specifications.
