C6D40065H

Overview

The Wolfspeed C6D40065H is a discrete Silicon Carbide (SiC) Schottky diode designed for industrial applications. It features a 650 V blocking voltage and an average forward current rating of 40 A. The device utilizes a TO-220-3 package with through-hole mounting. Key electrical parameters include a maximum reverse leakage current of 10 µA at rated voltage and a typical forward voltage drop of 1.7 V at 40 A. It operates within a junction temperature range of -55°C to +175°C, offering high thermal stability and low conduction losses compared to silicon alternatives.

Feature Summary

• Ultra-low reverse recovery charge enabling efficient high-frequency switching
• High-temperature operation capability up to 175°C junction temperature
• Robust ruggedness against short-circuit events and thermal cycling

Applications

• Industrial motor drives and inverters
• Uninterruptible power supplies (UPS)
• Solar micro-inverters and string inverters

Procurement Notes

Verify the specific suffix code on the datasheet to confirm pinout configuration and packaging variations. Ensure the procurement channel provides original manufacturer documentation to validate authenticity. Cross-reference the RoHS and REACH compliance declarations with current regulatory requirements before finalizing orders.

Selection Notes

Select this component when system design requires a 650 V SiC rectifier with a 40 A continuous current rating in a TO-220-3 form factor. Evaluate thermal management solutions to maintain junction temperatures below 175°C under peak load conditions. Compare total system efficiency gains against silicon counterparts to justify the material choice based on switching frequency requirements.

Part Context

This part belongs to Wolfspeed's discrete Silicon Carbide Schottky diode portfolio, specifically engineered for power conversion systems. It represents an advancement over traditional silicon diodes by reducing switching losses and improving overall power density. The product line targets demanding industrial environments requiring high reliability and thermal performance.

Replacement Considerations

Direct replacements must match the 650 V rating, 40 A current capacity, and TO-220-3 package. Verify that substitute components offer comparable reverse leakage characteristics and forward voltage drops to ensure circuit compatibility without redesigning thermal or drive circuits.
