C4D10120A

Overview

The Wolfspeed C4D10120A is a fourth-generation Silicon Carbide Schottky diode rated for 1200 V repetitive peak reverse voltage and 10 A continuous forward current at elevated temperatures. It utilizes a TO-220-2 through-hole package with a junction-to-case thermal resistance of 0.9 °C/W. The device operates within a temperature range of -55°C to +175°C, featuring a maximum forward voltage of 1.8 V at 10 A and 25°C, and a non-repetitive surge current capability of 71 A.

Feature Summary

• Zero reverse recovery charge due to majority carrier operation
• Positive temperature coefficient for forward voltage enabling safe paralleling
• Temperature-independent switching behavior

Applications

• Industrial switched mode power supplies
• Uninterruptible and auxiliary power supplies
• Boost stages for Power Factor Correction (PFC) and DC-DC converters
• Solar inverters

Procurement Notes

Verify the specific revision status against the latest Wolfspeed datasheet prior to finalizing designs. Confirm that the TO-220-2 mounting torque requirements are met during assembly. Ensure thermal management solutions account for the specified junction-to-case thermal resistance values under actual operating conditions.

Selection Notes

Select this component when high-frequency operation and reduced cooling requirements are necessary compared to silicon-based solutions. The positive temperature coefficient allows for easy paralleling without thermal runaway concerns. Verify that the 1200V rating aligns with system voltage spikes and that the TO-220-2 package fits the mechanical constraints.

Part Context

This part belongs to Wolfspeed's fourth-generation 1200V Silicon Carbide Schottky diode lineup. It is designed to replace traditional silicon rectifiers in high-efficiency power electronics systems. The device supports higher power densities and frequencies while lowering overall system costs through improved thermal performance.

Replacement Considerations

Direct pin-compatible replacements within the same series include surface-mount variants like the C4D10120E in a DPAK-2 package, though thermal and mechanical integration must be re-evaluated.
