BYG20J-E3/TR3

Overview

The BYG20J-E3/TR3 is an ultrafast avalanche rectifier manufactured by Vishay General Semiconductor. It features a glass passivated junction in a low-profile SMA (DO-214AC) surface-mount package. The device supports a maximum repetitive peak reverse voltage of 600 V and an average forward current of 1.5 A. Key electrical characteristics include a maximum instantaneous forward voltage of 1.4 V at 1.5 A, a reverse recovery time of 75 ns, and a non-repetitive peak forward surge current of 30 A. It operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• Ultrafast reverse recovery time for high-frequency switching applications
• Avalanche energy rating capability for inductive load switching
• Glass passivated pellet chip junction for reliability
• Soft recovery characteristics to minimize electromagnetic interference

Applications

• High frequency rectification in power supplies
• Inverters and converters
• Freewheeling diodes in consumer, automotive, and telecommunication equipment

Procurement Notes

Verify the specific ordering code suffix against the manufacturer's documentation to confirm compliance requirements. The E3 suffix indicates RoHS compliance, while TR3 denotes a 7500-unit reel quantity. Confirm that the base part number matches the required voltage rating, as the BYG20 series includes variants with different reverse voltage capabilities.

Selection Notes

Select this component when a 600 V blocking voltage and 1.5 A continuous current are required in a compact surface-mount form factor. Ensure the application demands an ultrafast recovery time around 75 ns. Verify thermal management requirements, as the device relies on lead and ambient cooling paths defined in the datasheet thermal resistance curves.

Part Context

This component belongs to the BYG20 series of ultrafast SMD rectifiers from Vishay. The series encompasses multiple voltage ratings, including 200 V, 400 V, and 600 V options. The BYG20J specifically designates the 600 V variant within this family, sharing identical physical dimensions and general electrical profiles with its lower-voltage counterparts.

FAQ

Is the BYG20J-E3/TR3 qualified for automotive applications?

No, the standard E3 version is commercial grade. Automotive qualification requires the HE3 or HM3 suffixes, which indicate AEC-Q101 qualification.

What does the polarity marking on the package indicate?

The color band on the component casing denotes the cathode end of the diode.
