Overview
The BYM07-400HE3_B/H is a general-purpose rectifier diode from Vishay's SUPERECTIFIER series, designed for fast recovery applications. It features a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current of 500 mA. The device utilizes the DO-213AA (GL34) surface-mount package. Key electrical characteristics include a maximum non-repetitive surge forward current rating and a specified reverse recovery time of 50 ns. The component operates within a junction temperature range of -55°C to +150°C.
Feature Summary
- Fast recovery performance with a reverse recovery time of 50 ns
- General-purpose rectification capability in a compact surface-mount package
- High thermal stability supporting operation up to 150°C junction temperature
Applications
- Fast switching power supplies
- DC-DC converter circuits
- Free-wheeling rectification in inductive load protection
Procurement Notes
Verify the specific suffix B/H against official Vishay documentation to confirm tape-and-reel packaging specifications and lead-free compliance status. Ensure the ordering part number matches the required quantity per reel. Cross-reference the datasheet revision date to validate parameter consistency before finalizing procurement orders.
Selection Notes
Select this component when a 400 V blocking voltage and 500 mA continuous current are required in a GL34 footprint. The 50 ns reverse recovery time makes it suitable for higher frequency applications compared to standard rectifiers. Evaluate thermal management requirements given the 150°C maximum junction temperature limit.
Part Context
This diode belongs to Vishay's SUPERECTIFIER family, which emphasizes fast recovery characteristics for efficient power conversion. The BYM07 series is engineered for surface-mount assembly, offering reliability in space-constrained designs. It serves as a discrete solution for replacing larger through-hole rectifiers in modern electronic equipment.
Replacement Considerations
Check for direct equivalents such as BYM07-400-E3/83 or BYM07-400HE3_B/I. Verify that substitute parts maintain identical pinout configurations, voltage ratings, and package dimensions to ensure mechanical and electrical compatibility without circuit redesign.
