HS3A

Single Diodes Overview

The HS3A is a high-efficiency surface mount rectifier manufactured by Taiwan Semiconductor Corporation. It features a single-phase configuration housed in the DO-214AB (SMA) package. The device supports a maximum repetitive peak reverse voltage of 50 V and an average forward rectified current of 3 A. Key electrical parameters include a maximum DC blocking voltage of 50 V, a forward voltage drop of 1 V at rated current, and a reverse leakage current of 10 uA. The component exhibits a fast recovery time of 50 ns and can withstand a maximum surge current of 150 A. It operates within a junction temperature range of -55 °C to +150 °C.

Single Diodes Feature Summary

• High-efficiency surface mount construction for compact circuit design
• Fast recovery characteristics with 50 ns switching speed
• Glass passivation for long-term reliability and stability

Single Diodes Applications

• General-purpose rectification in power supply circuits
• Freewheeling diode applications in inductive loads
• DC-DC converter output rectification

Single Diodes Procurement Notes

Verify the specific suffix code on the component marking to confirm the exact voltage rating, as the HS3A series spans multiple voltage options. Confirm RoHS compliance status through the manufacturer's official documentation prior to integration. Ensure the ordering quantity matches the available reel or cut tape specifications provided by the supplier.

Single Diodes Selection Notes

Select this component when a 3 A current capacity and 50 V reverse voltage rating are required in a surface mount form factor. The 50 ns recovery time makes it suitable for higher frequency switching applications compared to standard rectifiers. Evaluate thermal management requirements based on the DO-214AB package limitations and the specified maximum operating temperature.

Single Diodes Part Context

The HS3A belongs to the HS series of high-efficiency rectifiers from Taiwan Semiconductor. This series is designed to replace bulkier axial leaded components in modern electronics. The HS3A specifically denotes the 50 V variant within the broader HS family, which includes other voltage ratings such as 100 V, 200 V, and up to 1000 V, all sharing similar physical dimensions and general performance profiles.

Single Diodes Replacement Considerations

Direct replacements must match the 3 A current rating, 50 V reverse voltage, 50 ns recovery time, and DO-214AB package. Verify pinout compatibility and thermal characteristics before substitution.
