BYG20JHM3_A/I

Overview

The BYG20JHM3_A/I is an ultrafast avalanche rectifier from Vishay General Semiconductor, rated for a maximum repetitive peak reverse voltage of 600 V and an average forward current of 1.5 A. It features a soft recovery characteristic with an ultrafast reverse recovery time of 75 ns and a maximum instantaneous forward voltage of 1.4 V at 1.5 A. The device supports a peak forward surge current of 30 A and operates within a junction temperature range of -55 °C to +150 °C. Packaged in the low-profile SMA (DO-214AC) surface-mount format, it meets MSL level 1 standards and is qualified under AEC-Q101.

Feature Summary

• Avalanche-rated capability for non-repetitive pulse energy absorption up to 20 mJ
• Soft recovery characteristics designed to minimize electromagnetic interference
• Glass passivated pellet chip junction for enhanced reliability
• Halogen-free construction compliant with RoHS directives

Applications

• High frequency rectification in power supply circuits
• Inverter and converter topologies
• Freewheeling diodes for automotive systems
• Telecommunication equipment

Procurement Notes

Verify that the specific ordering code matches the required suffixes for halogen-free status and AEC-Q101 qualification. Confirm package dimensions against the SMA outline drawing before finalizing assembly designs. Ensure thermal management strategies account for the specified thermal resistance values under actual operating conditions.

Selection Notes

Select this component when high-frequency switching performance and avalanche ruggedness are required in a compact surface-mount footprint. The 600 V rating suits applications requiring higher voltage margins than lower-rated variants. Verify compatibility with automated placement equipment due to the low profile package design.

Part Context

This part belongs to the BYG20 series of ultrafast SMD rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different voltage ratings, such as 200 V and 400 V options. All members share the same DO-214AC package and core electrical architecture optimized for high-speed switching applications.

Replacement Considerations

Cross-reference with other Vishay BYG20 series parts like BYG20G or BYG20D if voltage requirements differ. Verify pinout and physical dimensions match the SMA (DO-214AC) footprint before substituting.
