Overview
The BYM12-300HE3_B/H is a standard rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 300 V and an average forward rectified current of 1 A. The device utilizes a DO-213AB (MELF) surface-mount package. It operates within a junction temperature range of -65°C to +175°C. The component is RoHS compliant, indicated by the 'E3' suffix, and is designed for general-purpose rectification applications requiring reliable performance in compact surface-mount layouts.
Feature Summary
- Surface-mount construction in a MELF-style DO-213AB package for automated assembly compatibility
- High-temperature operation capability with a junction temperature range extending to +175°C
- Lead-free construction compliant with RoHS directives
Applications
- General-purpose rectification in power supply circuits
- DC-to-AC conversion stages
- Protection circuits requiring fast recovery characteristics
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and compliance status. Confirm that the DO-213AB package dimensions match the target PCB footprint. Check for any recent lifecycle notices or obsolescence warnings directly from Vishay before finalizing procurement plans.
Selection Notes
Select this component when a surface-mount standard rectifier with 300 V blocking voltage and 1 A current rating is required. Ensure the application environment supports the specified operating temperature range. Consider the reverse recovery time specifications if used in high-frequency switching applications to minimize switching losses.
Part Context
This part belongs to the BYM12 series of standard recovery rectifiers from Vishay. The series offers various voltage ratings within the same DO-213AB package family, allowing for design flexibility. The HE3 technology typically implies enhanced reliability and lower forward voltage compared to standard silicon alternatives, though specific electrical comparisons require direct datasheet verification.
Replacement Considerations
Cross-reference with other Vishay parts in the BYM12 series for different voltage ratings. Verify pinout compatibility with alternative manufacturers offering DO-213AB rectifiers. Ensure substitute components meet the same thermal and electrical specifications for direct replacement.
