PUAD10BC

Overview

The PUAD10BC is an ultra-fast recovery rectifier manufactured by Taiwan Semiconductor Corporation. It features a dual common cathode configuration housed in a D2PAK-3 (TO-263-3) surface-mount package. The device supports a maximum repetitive peak reverse voltage of 600 V and provides a continuous forward current of 10 A. Key electrical characteristics include a typical forward voltage of 1.49 V at rated current, a maximum reverse leakage current of 5 µA, and a fast switching speed with a recovery time of 25 ns. It withstands a surge current of up to 190 A and operates within a junction temperature range from -55 °C to +175 °C.

Feature Summary

• Ultra-fast recovery performance with 25 ns switching speed for high-frequency efficiency
• Dual common cathode topology enabling efficient bridge rectification in compact designs
• High thermal stability supporting operation up to 175 °C junction temperature
• Robust surge current handling capability for reliable power supply protection

Applications

• High-frequency DC/DC converter output rectification
• Free-wheeling diodes in synchronous buck converters
• Isolated flyback and forward converter secondary rectification
• Power factor correction (PFC) circuits requiring fast recovery

Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and electrical tolerances. Confirm RoHS compliance status through manufacturer documentation prior to integration. Ensure ESD precautions are observed during handling due to the sensitive semiconductor junction. Validate that the D2PAK-3 footprint matches your PCB design guidelines. Check for any recent lifecycle notifications regarding production status.

Selection Notes

Select this component when designing circuits requiring fast switching speeds to minimize reverse recovery losses. The dual common cathode arrangement simplifies layout compared to discrete single-diode solutions. Ensure the thermal management system can handle the power dissipation associated with 10 A continuous current. Verify that the 600 V rating exceeds the maximum transient voltages present in the application environment.

Part Context

This part belongs to Taiwan Semiconductor's ultra-fast rectifier portfolio, designed for modern power electronics. It complements other devices in the PUAD series, offering consistent performance across various voltage ratings. The D2PAK-3 package is widely used in industrial and consumer power supplies for its balance of current capacity and thermal performance.

Replacement Considerations

Direct substitutes must match the 600 V, 10 A, dual common cathode specification with comparable 25 ns recovery time. Verify pin compatibility for D2PAK-3 packages before swapping manufacturers. Cross-reference with other ultra-fast rectifiers ensuring identical thermal and electrical limits.
