BYG23M-M3/TR

Overview

The BYG23M-M3/TR is an ultrafast avalanche SMD rectifier manufactured by Vishay General Semiconductor. It features a glass passivated pellet chip junction in a low-profile SMA (DO-214AC) package. Key electrical parameters include a maximum repetitive peak reverse voltage of 1000 V, an average forward current of 1.5 A at 65 °C, and a peak forward surge current of 30 A. The device exhibits a maximum reverse recovery time of 75 ns and a typical thermal resistance from junction to case of 25 °C/W. It operates within a temperature range of -55 to +150 °C.

Feature Summary

• Ultrafast reverse recovery characteristics suitable for high-frequency applications
• Avalanche rated capability for energy dissipation in inductive switching loads
• Glass passivated junction providing robust protection against voltage transients
• Halogen-free and RoHS-compliant construction with matte tin plated leads

Applications

• High frequency rectification in switching mode converters
• Freewheeling diodes in consumer and computer electronics
• Inverter circuits for automotive and telecommunication systems

Procurement Notes

Verify the specific ordering code suffix to confirm compliance requirements. The M3 suffix indicates halogen-free and RoHS-compliant commercial grade material. Confirm the delivery mode matches the required base quantity, such as TR for 1800 units or TR3 for 7500 units on plastic tape reels. Ensure the component meets the necessary moisture sensitivity level standards for automated placement processes.

Selection Notes

Select this component when designing circuits requiring high reverse voltage blocking capabilities alongside fast switching speeds. The SMA package offers a compact footprint ideal for space-constrained surface mount designs. Consider the avalanche rating if the application involves inductive load switching where non-repetitive pulse energy absorption is necessary. Validate thermal performance based on the specific ambient temperature and mounting conditions.

Part Context

This part belongs to the BYG23 series of ultrafast avalanche rectifiers from Vishay. The series includes variants with different packaging and qualification levels, such as HE3 and HM3 codes for AEC-Q101 automotive qualification. The standard M3 variant provides commercial grade reliability with halogen-free materials, distinguishing it from the specialized automotive qualified versions available in the same family.

Replacement Considerations

Direct substitutes within the Vishay portfolio include BYG23M-E3/TR for RoHS-only compliance or BYG23MHM3_A/H for AEC-Q101 automotive qualification. Cross-manufacturer replacements must match the 1000 V reverse voltage, 1.5 A current rating, and DO-214AC package dimensions.
