C3D25170H

Overview

The C3D25170H is a Silicon Carbide Schottky diode from Wolfspeed, classified as a Z-Rec™ rectifier. It utilizes a TO-247-2 through-hole package for robust mounting. The device features a maximum repetitive reverse voltage (VRRM) of 1700 V and a continuous forward current (IF; TC) rating of 26.3 A. These specifications define its electrical limits for high-voltage power conversion applications.

Feature Summary

• Utilizes silicon carbide material technology for superior thermal performance compared to traditional silicon devices.
• Features Z-Rec™ rectifier architecture designed to minimize reverse recovery charge and associated switching losses.
• Constructed in a TO-247-2 through-hole package to facilitate efficient heat dissipation and mechanical stability.

Applications

• High-efficiency DC/DC converters
• Uninterruptible Power Supplies (UPS)
• Industrial motor drives

Procurement Notes

Verify the specific datasheet revision and ordering suffixes directly with Wolfspeed or authorized distributors to ensure component authenticity. Confirm that the TO-247-2 package dimensions match your PCB footprint requirements. Cross-reference the 1700 V and 26.3 A ratings against your system's peak voltage and current stress calculations to ensure adequate safety margins.

Selection Notes

Select this component when designing systems requiring high blocking voltage capability combined with low reverse recovery characteristics. The TO-247-2 package is suitable for applications where through-hole mounting provides necessary mechanical strength. Ensure thermal management solutions can handle the power dissipation associated with the specified forward current at the relevant case temperature.

Part Context

This component belongs to Wolfspeed's discrete silicon carbide product line, which targets high-power density and high-efficiency energy conversion systems. The Z-Rec™ series specifically addresses the need for fast-switching rectifiers in hard-switched topologies, offering improved efficiency over conventional silicon diodes in similar voltage classes.

Replacement Considerations

Direct pin-to-pin replacements should be verified against the original manufacturer's substitution guide. Consider alternative SiC Schottky diodes with compatible 1700 V ratings and TO-247-2 packaging if sourcing constraints exist, ensuring equivalent reverse recovery charge and thermal resistance values are met.
