HS3F R7G

Single Diodes Overview

The HS3F R7G is a single fast recovery rectifier manufactured by Taiwan Semiconductor Corporation, designed for surface-mount applications in the DO-214AA-2 (SMA) package. It features a maximum repetitive peak reverse voltage of 300 V and an average forward rectified current of 3 A. The device exhibits a typical forward voltage drop of 1 V and a maximum non-repetitive peak surge current capability of 100 A. Key electrical characteristics include a low reverse leakage current of 10 uA and a fast recovery time of 50 ns. It operates within a junction temperature range from -55 °C to +150 °C.

Single Diodes Feature Summary

• Freewheeling diodes in motor drive systems

Single Diodes Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'R7G' corresponds to the required reel packaging format. Ensure compliance with RoHS directives and REACH regulations as specified in the official datasheet. Validate that the DO-214AA-2 footprint matches the target PCB design constraints before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a 3 A current rating and 300 V blocking voltage are required in a compact SMA package. The 50 ns recovery time makes it suitable for higher frequency switching applications compared to standard rectifiers. Consider the AEC-Q101 qualification if the application demands automotive-grade reliability standards. Evaluate thermal management requirements based on the 1 V forward voltage drop at rated current.

Single Diodes Part Context

This part belongs to the HS3 series of High Efficient Recovery Rectifiers from Taiwan Semiconductor. The series offers various voltage ratings including 200 V, 300 V, 400 V, and 600 V options. The HS3F variant specifically targets the 300 V market segment. The R7G suffix typically denotes tape-and-reel packaging for automated assembly processes.

Single Diodes Replacement Considerations

Potential substitutes include other 3 A, 300 V fast recovery diodes in the SMA package such as the MUR330 or FR303. Verify pinout compatibility and ensure equivalent or superior electrical parameters for recovery time and surge current.
