BYG10KHE3_A/H

Overview

The BYG10KHE3_A/H is a standard recovery rectifier from Vishay Semiconductors, housed in the DO-214AC (SMA) surface-mount package. It features an 800 V reverse voltage rating and supports a continuous forward current of 1.5 A. The device exhibits a maximum forward voltage of 1.15 V and a reverse leakage current of 1 µA. Its peak forward surge current capability is 30 A, with a typical reverse recovery time of 4 µs. Operating temperatures range from -55 °C to +150 °C junction temperature. This component holds AEC-Q101 qualification for automotive reliability standards.

Feature Summary

• Avalanche rated construction for robustness against transient voltage events
• AEC-Q101 qualified for automotive-grade reliability requirements
• Glass passivated junction structure ensuring high reliability conditions

Applications

• Automotive electronics systems requiring standardized rectification
• General-purpose power supply circuits
• Freewheeling diode applications in switching converters

Procurement Notes

Verify the specific suffix 'A/H' corresponds to the required tape-and-reel or cut-tape packaging configuration before ordering. Confirm that the 800V rating aligns with the system's peak inverse voltage requirements. Ensure the DO-214AC footprint matches the PCB design constraints. Cross-reference the AEC-Q101 certification status if automotive compliance is mandatory for the final assembly.

Selection Notes

Select this component when an 800V blocking capability is necessary within a compact SMA surface-mount form factor. The 1.5A average current rating suits moderate power applications where space is limited. Consider the 4 µs recovery time for general frequency operations rather than high-speed switching environments. The avalanche capability provides additional margin for inductive load switching scenarios compared to non-avalanche variants.

Part Context

This part belongs to the BYG10 series of SUPERECTIFIER devices, which utilize glass-passivated junction technology for enhanced durability. The series is designed to meet stringent environmental standards, including RoHS compliance. Vishay positions these components as reliable replacements for through-hole equivalents in modern surface-mount manufacturing processes.

Replacement Considerations

Direct substitutes include other Vishay BYG10 series parts with compatible voltage and current ratings, such as BYG10JHE3_A/H for lower voltage needs. Verify pinout compatibility and thermal characteristics when replacing with generic SMA rectifiers.
