BYG20GH

Overview

The BYG20GH is a high-efficiency fast recovery rectifier diode manufactured by Taiwan Semiconductor Corporation. It features a 1.5A average forward current rating and a 400V repetitive peak reverse voltage. The device utilizes a glass-passivated junction for enhanced reliability and operates within a temperature range of -55°C to +150°C. With a typical reverse recovery time of 75ns, it is designed for surface-mount applications in the DO-214AC (SMA) package.

Feature Summary

• High-efficiency fast recovery performance with 75ns reverse recovery time
• Glass-passivated junction construction for improved stability
• Wide operating temperature range from -55°C to +150°C

Applications

• Power supply circuits
• General-purpose rectification
• DC-DC converter stages

Procurement Notes

Verify the manufacturer marking matches Taiwan Semiconductor Corporation specifications. Confirm the package type is DO-214AC (SMA) and the voltage rating is 400V. Ensure the component is original and free from physical damage before integration into designs.

Selection Notes

Select this component when a 1.5A current capacity and 400V blocking voltage are required in a compact surface-mount form factor. The 75ns recovery speed makes it suitable for higher frequency switching applications compared to standard rectifiers.

Part Context

This part belongs to the BYG series of high-efficiency rectifiers from Taiwan Semiconductor. These devices are engineered to replace bulkier through-hole alternatives in modern electronics, offering comparable electrical performance in a smaller SMA footprint.

Replacement Considerations

Check for direct substitutes with identical 1.5A/400V ratings and 75ns recovery times in the SMA package. Verify pinout compatibility and thermal characteristics before substituting.
