BYG20D

Overview

The BYG20D is a high-efficiency surface mount rectifier manufactured by Taiwan Semiconductor. It features a 1.5 A average forward rectified current and a maximum repetitive peak reverse voltage of 200 V. The device utilizes a DO-214AC (SMA) case with glass passivated junctions for low reverse current. Key electrical characteristics include a maximum instantaneous forward voltage of 1.3 V, a peak forward surge current of 30 A, and a maximum reverse recovery time of 75 ns. It operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• Glass passivated junction chip designed for low reverse current and soft recovery characteristics
• Fast switching capability optimized for high efficiency applications
• High surge current capability suitable for demanding power conditions
• Compliant with RoHS Directive 2011/65/EU and WEEE 2002/96/EC standards

Applications

• Automated placement in surface mount assembly lines
• General purpose rectification in high efficiency power supplies
• DC-DC converter circuits requiring fast switching performance

Procurement Notes

Verify the specific suffix codes on the component marking to confirm exact specifications such as halogen-free status or automotive qualification. Confirm the manufacturer datasheet version matches the production batch requirements. Ensure the DO-214AC package dimensions align with the PCB footprint design. Check for any specific moisture sensitivity level handling instructions during storage and reflow soldering processes.

Selection Notes

Select this component when a 1.5 A current rating and 200 V reverse voltage are required in a compact SMA package. Consider the 75 ns reverse recovery time for switching frequency compatibility. Evaluate the thermal resistance and operating temperature range against the system's heat dissipation capabilities. Compare the forward voltage drop against alternative diodes to ensure optimal efficiency in the target circuit design.

Part Context

This part belongs to the BYG20 series of high-efficient surface mount rectifiers from Taiwan Semiconductor. The series covers voltage ratings from 200 V to 600 V with a consistent 1.5 A current rating. These devices are engineered for general-purpose rectification where space constraints and switching speed are critical factors in the overall system performance.

Replacement Considerations

Cross-reference with Vishay BYG20D for equivalent electrical parameters in the DO-214AC package. Verify pinout compatibility and mechanical dimensions before substitution. Ensure the replacement part meets the same RoHS and environmental compliance standards required by the original design.
