Overview
The BYM12-50HE3_B/H is a fast recovery rectifier manufactured by Vishay Semiconductors. It features a maximum average forward rectified current of 1 A and a repetitive peak reverse voltage of 50 V. The device exhibits a maximum reverse recovery time of 50 ns and a peak forward surge current capability of 30 A. It operates within a junction temperature range of -65 °C to +175 °C and utilizes the DO-213AB (GL41) MELF package.
Feature Summary
- Fast recovery performance with a 50 ns reverse recovery time for efficient switching applications
- High thermal stability supporting operation up to +175 °C junction temperature
- Automotive qualification compliant with AEC-Q101 standards
Applications
- Automotive electronics systems requiring AEC-Q101 qualified components
- General purpose rectification in low voltage DC circuits
- Freewheeling diodes in inductive load switching applications
Procurement Notes
Verify the specific suffix B/H against official datasheets to confirm package and marking details. Confirm availability status as this variant may be designated for non-new designs. Ensure compatibility with existing PCB footprints for the DO-213AB package before integration into production schedules.
Selection Notes
Select this component when a 50 V rating and 1 A continuous current are required alongside fast switching characteristics. The AEC-Q101 qualification makes it suitable for automotive environments. Consider the MELF form factor for space-constrained surface mount designs requiring high thermal reliability.
Part Context
This part belongs to the BYM12 series of fast recovery rectifiers from Vishay. It shares the same electrical specifications as the BYM12-50HE3_A/H but differs in packaging or marking configuration indicated by the suffix. The series is designed for general purpose and automotive applications requiring reliable high-speed rectification.
Replacement Considerations
The BYM12-50HE3_A/H is a confirmed substitute with identical electrical ratings. Verify that the physical package dimensions and pinout remain compatible with the target assembly, as suffix variations may indicate minor manufacturing differences.
