BYG24D-E3/TR

Overview

The BYG24D-E3/TR is a fast avalanche surface-mount rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a glass passivated junction and operates in the SMA (DO-214AC) package. The device supports a maximum repetitive peak reverse voltage of 200 V and an average forward current of 1.5 A at 65 °C. Electrical characteristics include a maximum instantaneous forward voltage of 1.25 V at 1.5 A, a maximum reverse current of 1 µA at 25 °C, and a maximum reverse recovery time of 140 ns. The component withstands a peak forward surge current of 30 A and handles a non-repetitive pulse energy of 20 mJ in avalanche mode. Operating junction and storage temperatures range from -55 °C to +150 °C.

Feature Summary

• Fast reverse recovery time with soft recovery characteristics
• Glass passivated junction for low reverse current
• Avalanche rated for inductive load switching applications
• Low profile package suitable for automated placement

Applications

• High frequency rectification in switching mode converters
• Freewheeling applications in inverters
• Consumer electronics power supplies
• Computer equipment power circuits
• Automotive electronic systems

Procurement Notes

Verify that the ordering suffix matches the required delivery mode and base quantity. The standard commercial grade uses the E3 suffix for RoHS compliance. Automotive qualified versions require specific HE3 or HM3 suffixes. Confirm the package code corresponds to the intended reel diameter and tape specifications before finalizing procurement orders.

Selection Notes

Select this component when a 200 V blocking capability is required alongside high-speed switching performance. The avalanche rating makes it suitable for inductive load environments where energy dissipation occurs during switch-off. Ensure thermal management accounts for the specified junction-to-case resistance. Verify that the operating temperature range aligns with the application's environmental constraints.

Part Context

This part belongs to the BYG24 series of fast avalanche SMD rectifiers, which includes variants with different voltage ratings such as 400 V and 600 V. All members share identical physical dimensions and general electrical characteristics except for the breakdown voltage limits. The series utilizes the DO-214AC package to provide a compact solution for modern surface-mount assembly processes.

Replacement Considerations

Direct substitutes within the same family include BYG24G and BYG24J, provided the circuit voltage requirements exceed 200 V. Cross-manufacturer replacements must match the 1.5 A current rating, 200 V reverse voltage, and SMA package footprint while maintaining comparable reverse recovery times.
