RURP880CC

Overview

The Harris Corporation RURP880CC is a silicon rectifier diode featuring avalanche characteristics and ultra-fast soft recovery performance. It is configured as a single-element, one-phase device housed in a TO-220AC flange mount package with the case connected to the cathode. The component supports an average forward current of 8A and withstands a maximum DC reverse voltage of 800V. Key electrical parameters include a maximum non-repetitive peak forward surge current of 100A, a maximum forward voltage of 2.1V at rated current, and a junction operating temperature range from -65°C to 175°C.

Feature Summary

• Ultra-fast soft recovery characteristic for high-speed switching applications
• Avalanche technology enabling robust energy handling capabilities
• Flange mount construction with cathode-connected case for efficient thermal dissipation

Applications

• High-frequency power supply circuits
• Induction heating systems
• Motor drive freewheeling paths

Procurement Notes

Verify the manufacturer source carefully, as Harris Corporation's semiconductor division was acquired by Intersil, which later became part of Renesas Electronics. Confirm that the specific part number corresponds to the original Harris production run or the subsequent lineage documentation. Ensure the datasheet explicitly lists the RURP880CC model to distinguish it from similar series components like the RURP860CC or RURP3090.

Selection Notes

Select this component when designing circuits requiring fast recovery times combined with moderate current handling in a chassis-mountable form factor. The 800V rating suits medium-voltage AC-DC conversion stages. Evaluate the thermal resistance of the TO-220AC package against the system's heat sink capacity to ensure the junction temperature remains within the specified 175°C limit during continuous operation.

Part Context

This device belongs to the Harris RURP series of ultra-fast recovery rectifiers. These components were engineered for demanding power electronics environments where standard recovery diodes would fail due to excessive switching losses or reverse recovery charge. The series typically includes variants with different voltage and current ratings to cover a broad spectrum of industrial power conversion needs.

Replacement Considerations

Cross-reference with other ultra-fast recovery diodes in the TO-220AC package offering comparable 800V and 8A ratings. Verify that any substitute matches the specific soft recovery profile and avalanche ruggedness requirements of the original design.
