C6D40065G

Overview

The C6D40065G is a 6th generation discrete Silicon Carbide (SiC) Schottky diode manufactured by Wolfspeed. It features a 650 V reverse voltage rating and a 40 A forward current capability. The device utilizes ZRec technology to minimize reverse recovery charge, enhancing efficiency in high-frequency switching applications. Designed for robust performance, it supports a maximum junction temperature of 175 °C and operates within an extended temperature range from -55 °C to +175 °C. The component is housed in a TO-247-3 package, suitable for through-hole mounting in industrial power electronics systems.

Procurement Notes

Verify the specific suffix and packaging configuration against official Wolfspeed documentation before procurement. Confirm that the requested variant matches the required current and voltage ratings for your design. Ensure compliance with RoHS directives if applicable to your region. Cross-reference the manufacturer part number with distributor listings to avoid counterfeit components. Validate lead times and availability directly with authorized suppliers.

Selection Notes

Select this component for designs requiring low reverse recovery charge to improve efficiency at high frequencies. Consider the TO-247-3 package for adequate thermal dissipation in through-hole layouts. Evaluate the 650 V rating against peak transient voltages in the circuit. Compare total system losses against alternative SiC devices to optimize overall performance. Ensure gate drive and snubber circuits are compatible with the switching speed.

Part Context

This component belongs to Wolfspeed's 6th generation Silicon Carbide Schottky diode portfolio. It complements other discrete SiC devices like the C3M series MOSFETs for complete power stage solutions. The ZRec technology distinguishes it from standard Schottky diodes by reducing tail current during turn-off. This family targets high-power density applications where thermal management and efficiency are critical constraints.

Replacement Considerations

Direct substitutes include other 650 V, 40 A SiC Schottky diodes in TO-247-3 packages from Wolfspeed or competitors. Verify pinout compatibility and thermal resistance values when cross-referencing. Check if alternative devices meet the same reverse recovery charge specifications. Ensure the replacement maintains the required 175 °C junction temperature rating.
