BYG20JHE3_A/H

Overview

The BYG20JHE3_A/H is an ultrafast avalanche rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a glass passivated pellet chip junction and operates in the 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 parameters include a maximum instantaneous forward voltage of 1.4 V at 1.5 A, a maximum DC reverse current of 1 µA at 25 °C, and an ultrafast reverse recovery time of 75 ns. It withstands a peak forward surge current of 30 A and dissipates up to 20 mJ of pulse energy in avalanche mode. The component is rated for operating junction and storage temperatures ranging from -55 °C to +150 °C.

Feature Summary

• Ultrafast reverse recovery characteristics with soft recovery behavior
• Avalanche capability for non-repetitive pulse energy dissipation
• Glass passivated pellet chip junction construction
• Low reverse leakage current

Applications

• High frequency rectification in power supplies
• Inverter circuits
• Converter applications
• Freewheeling diodes for consumer electronics
• Automotive systems
• Telecommunication equipment

Procurement Notes

Verify that the ordering code includes the HE3 suffix to confirm AEC-Q101 automotive qualification. Ensure the base part number matches the required voltage rating, as the J suffix specifically denotes the 600 V variant within the BYG20 series. Confirm the package type corresponds to SMA (DO-214AC). Check for specific revision codes appended to the ordering code if required by design specifications.

Selection Notes

Select this component when high-frequency switching efficiency and avalanche ruggedness are required in a compact surface-mount form factor. The 600 V rating makes it suitable for higher voltage DC-DC conversion stages. Consider the thermal resistance values relative to the PCB copper area, as heat dissipation significantly impacts the allowable average forward current derating curve above ambient temperatures.

Part Context

This device belongs to the BYG20D, BYG20G, and BYG20J family of ultrafast SMD rectifiers. All variants share identical physical dimensions, thermal characteristics, and general performance traits such as the 1.5 A current rating and 75 ns recovery time. The primary distinction lies in the maximum repetitive peak reverse voltage ratings: 200 V for the D variant, 400 V for the G variant, and 600 V for the J variant.
