RURD1560

Overview

The RURD1560 is a silicon avalanche rectifier diode array manufactured by Harris Corporation. It features a single pair common cathode configuration housed in a TO-218-3 Isolated Tab package. The device supports a maximum DC reverse voltage of 600V and an average forward current of 15A. Key electrical specifications include a reverse recovery time of 60ns, classifying it as a fast recovery diode. The component operates within a temperature range of -65°C to 175°C and has a non-repetitive peak forward surge current rating of 200A.

Feature Summary

• Avalanche-rated construction for robustness against transient energy events
• Fast recovery characteristics with a 60ns reverse recovery time
• Common cathode dual-diode configuration for efficient circuit design
• Isolated tab package option for simplified thermal management

Applications

• High-frequency switching power supplies
• Inductive load freewheeling circuits
• DC-DC converter output rectification
• Motor drive protection stages

Procurement Notes

Verify the specific manufacturer source, as historical data indicates production by Harris Corporation, which may involve legacy supply chains or acquisitions. Confirm that the TO-218-3 package variant matches the required isolation tab specifications for the target application. Ensure compliance with RoHS status if environmental regulations apply, noting potential discrepancies in available documentation regarding certification. Cross-reference datasheet revisions to confirm electrical parameters remain consistent with current design requirements.

Selection Notes

Select this component when high-voltage blocking capability up to 600V is required alongside moderate current handling at 15A. The avalanche rating makes it suitable for environments prone to voltage spikes. Consider the TO-218-3 package for through-hole mounting where thermal dissipation via the isolated tab is necessary. Evaluate the 60ns reverse recovery time against switching frequency requirements to minimize switching losses. Compare alternative single-element configurations if space constraints differ from the dual-diode array form factor.

Part Context

This part belongs to the series of high-voltage rectifier diodes designed for industrial and telecommunications applications. Harris Corporation historically specialized in RF and power components for defense and commercial sectors. The RURD1560 represents a discrete semiconductor solution for power conversion, distinct from integrated modules. Its classification as an avalanche diode indicates specific ruggedness testing beyond standard rectification capabilities.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with direct replacements by matching the 600V reverse voltage, 15A current rating, 60ns reverse recovery time, and TO-218-3 package dimensions. Ensure any alternative component maintains the common cathode configuration and avalanche rating if transient immunity is critical.
