BYG23MHE3_A/H

Overview

The BYG23MHE3_A/H is an ultrafast avalanche rectifier manufactured by Vishay General Semiconductor. It features a glass passivated pellet chip junction and operates in a single circuit configuration within the SMA (DO-214AC) package. The device supports a maximum repetitive peak reverse voltage of 1000 V and an average forward current of 1.5 A at 65 °C. Key electrical parameters include a maximum instantaneous forward voltage of 1.7 V, a peak forward surge current of 30 A, and a maximum reverse current of 5 µA. It exhibits an ultrafast reverse recovery time of 75 ns and can withstand a non-repetitive pulse energy of 20 mJ in avalanche mode.

Procurement Notes

Verify that the specific ordering code matches the required automotive qualification status. Confirm the suffix indicates compliance with RoHS directives and halogen-free requirements as specified for the HE3 variant. Ensure the package type aligns with automated placement requirements and check the maximum peak reflow temperature limits against your assembly process specifications.

Selection Notes

Select this component when high reverse voltage blocking capability and fast switching speeds are required in a compact surface mount form factor. Consider the avalanche rating if the application involves inductive loads or potential voltage spikes during switch-off. Evaluate thermal resistance values based on the specific PCB copper area and mounting conditions to ensure safe operating temperatures under expected load profiles.

Part Context

This part belongs to the BYG23M series of ultrafast SMD rectifiers from Vishay. It shares the same core electrical specifications as the commercial grade BYG23M-E3 but includes additional automotive qualification and environmental compliance features indicated by the HE3 suffix. The series is designed to replace through-hole components in modern high-density electronic designs requiring robust performance.

Replacement Considerations

Direct substitutes within the same family include the BYG23MHM3_A/H which offers identical electrical performance with halogen-free compliance. Other variants like the BYG23M-E3 provide similar functionality without automotive qualification. Verify pinout compatibility and thermal characteristics before substituting with parts from different manufacturers.
