PUAD8BCH

Overview

The PUAD8BCH is a dual common cathode ultra-fast recovery rectifier manufactured by Taiwan Semiconductor Corporation. It features a maximum repetitive peak reverse voltage of 100 V and an average forward rectified current of 4 A per diode. The device exhibits a typical reverse recovery time of 25 ns and a maximum reverse leakage current of 2 µA at 100 V. Forward voltage is specified at 850 mV when conducting 4 A. It operates within a junction temperature range of -55°C to +175°C and is housed in a Thin DPAK-2 (SMB) surface-mount package.

Feature Summary

Dual common cathode configuration for efficient bridge or center-tapped rectification
Ultra-fast recovery characteristics with 25 ns reverse recovery time
Automotive grade reliability certified under AEC-Q101 standards
High thermal stability supporting operation up to 175°C junction temperature

Applications

Automotive power supply circuits
DC-DC converter output rectification
Freewheeling diodes in inductive load switching
General purpose high-frequency rectification

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact electrical tolerances and packaging variations. Ensure compatibility with AEC-Q101 automotive qualification requirements if deploying in vehicle systems. Cross-reference datasheet parameters for thermal resistance and surge current ratings prior to integration into final designs.

Selection Notes

Select this component for applications requiring fast switching speeds and robust automotive-grade performance. The dual common cathode arrangement simplifies circuit topology compared to discrete single-diode solutions. Evaluate thermal management needs based on the SMB package constraints and expected operating currents to ensure reliable long-term operation.
