PU3DA

Single Diodes Overview

The PU3DA is a single ultra-fast recovery rectifier manufactured by Taiwan Semiconductor Corporation. It features a maximum repetitive peak reverse voltage of 200 V and an average forward rectified current of 3 A. The device utilizes a surface-mount DO-214AC (SMA) package. Key electrical characteristics include a maximum reverse leakage current of 2 µA at 200 V, a typical forward voltage of 930 mV at 3 A, and a fast reverse recovery time of 25 ns. The component operates within a junction temperature range of -55°C to 175°C.

Single Diodes Feature Summary

• Ultra-fast recovery performance with a 25 ns reverse recovery time for efficient switching applications
• High thermal stability supporting operation up to a 175°C junction temperature
• Robust 3 A average forward current rating in a compact surface-mount SMA package

Single Diodes Applications

• High-frequency DC-DC converter circuits
• Free-wheeling diodes in power supply designs
• Snubber circuits in switching mode power supplies

Single Diodes Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and tape/reel specifications. Ensure compatibility with RoHS3 and REACH regulations for your region. Confirm that the ordering code matches the required SMA package variant rather than other series packages like SOD-128.

Single Diodes Selection Notes

Select this component when a 200 V blocking capability and 3 A continuous current are required in a standard SMA footprint. The 25 ns reverse recovery time makes it suitable for higher frequency applications compared to standard recovery diodes. Verify that the thermal management design supports the specified junction temperature limits under expected load conditions.

Single Diodes Part Context

Taiwan Semiconductor Corporation specializes in discrete power rectifiers, including trench Schottky diodes and MOSFETs. The PU3DA belongs to their ultra-fast recovery rectifier lineup, designed for general-purpose high-efficiency power conversion. This product line emphasizes reliability and thermal performance for industrial and consumer electronics.

Single Diodes Replacement Considerations

Publicly confirmed substitute part numbers for the PU3DA are not available in the provided documentation. Cross-referencing requires matching the 200 V, 3 A, 25 ns trr, and DO-214AC package specifications from manufacturer datasheets.
