Overview
The BYM12-50HE3_B/I is a fast recovery rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a Superectifier structure with a cavity-free glass-passivated junction for high reliability. The device is housed in a DO-213AB (GL41) surface-mount package. Key electrical parameters include a maximum repetitive peak reverse voltage of 50 V and an average forward rectified current of 1 A. The maximum forward voltage is 1 V at 1 A, while the maximum reverse leakage current is 5 µA. The component supports a maximum surge forward current of 30 A and has a typical reverse recovery time of 50 ns. It operates within a junction temperature range of -65°C to +175°C.
Feature Summary
- Superectifier structure designed for high reliability under demanding conditions
- Cavity-free glass-passivated junction construction
- Suitable for automated placement processes
Applications
- Automotive electronics systems requiring AEC-Q101 qualified components
- High-frequency switching power supplies
- DC-DC converter circuits
Procurement Notes
Verify the specific suffix B/I against official Vishay documentation to confirm exact mechanical and marking specifications. Ensure compatibility with existing PCB footprints for the DO-213AB package. Confirm that the component meets all required automotive or industrial standards for the intended application environment before finalizing procurement.
Selection Notes
Select this component when a fast recovery rectifier with low reverse recovery charge is required in a compact surface-mount form factor. The 50V rating and 1A current capacity suit low-voltage, moderate-current applications. Consider the 50ns recovery time for efficiency in high-speed switching environments where standard rectifiers may cause excessive losses.
Part Context
This part belongs to the BYM12 series of ultrafast rectifiers from Vishay. These devices utilize proprietary Superectifier technology to combine the speed of ultrafast diodes with the robustness of standard recovery types. The series is widely used in applications demanding high reliability and efficient power conversion in small packages.
