BYG23M

Overview

The BYG23M is a high-efficiency surface mount rectifier manufactured by Taiwan Semiconductor. It features a glass passivated chip junction and is housed in a DO-214AC (SMA) package. The device supports a repetitive peak reverse voltage of 1000 V and an average forward current of 1.5 A. Key electrical parameters include a maximum forward voltage of 1.7 V at 1 A, a reverse recovery time of 65 ns, and a peak forward surge current capability of 50 A. The component operates within a junction temperature range of -55 to +150 °C.

Feature Summary

• Glass passivated chip junction for enhanced reliability
• Fast switching characteristics designed for high efficiency
• High surge current capability suitable for demanding power applications
• Automated placement compatible with standard manufacturing processes

Applications

• Free-wheeling circuits in power supplies
• Clamping applications in power electronics
• Snubber circuits for voltage suppression
• Demagnetization tasks in transformer-based designs

Procurement Notes

Verify the specific ordering code against the manufacturer's official documentation to ensure correct packaging quantities and tape-and-reel specifications. Confirm that the requested variant matches the required RoHS compliance and halogen-free status as defined in the datasheet. Cross-reference the marking code and date code requirements with your assembly specifications before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring fast recovery times and high avalanche energy ratings. The DO-214AC package is suitable for space-constrained surface mount layouts. Ensure the operating environment stays within the specified thermal limits and that the reverse voltage rating exceeds the peak circuit voltages to maintain safe operation margins.

Part Context

This part belongs to the BYG series of high-efficient surface mount rectifiers from Taiwan Semiconductor. It utilizes a glass passivation process to improve junction stability compared to standard epoxy encapsulated devices. The SMA footprint provides a compact solution for general-purpose rectification where faster switching speeds are preferred over standard recovery diodes.

Replacement Considerations

Direct substitutes must match the 1000V/1.5A rating and DO-214AC package. Verify equivalent reverse recovery times and avalanche capabilities if used in snubber or free-wheeling roles.
