Overview
The BYM12-400-E3/97 is a surface-mount glass-passivated ultrafast rectifier manufactured by Vishay General Semiconductor. It features a Superectifier structure and operates in the GL41 (DO-213AB) package. The device supports a maximum average forward rectified current of 1.0 A at 75 °C and withstands a maximum repetitive peak reverse voltage of 400 V. Key electrical characteristics include a maximum instantaneous forward voltage of 1.25 V, a peak forward surge current capability of 30 A, and an ultrafast maximum reverse recovery time of 50 ns. The component is rated for operating junction and storage temperatures ranging from -65 °C to +175 °C.

- Superectifier structure designed for high reliability under demanding conditions
- Cavity-free glass-passivated junction construction
- Ultrafast reverse recovery time with low switching losses
- High forward surge current capability
Applications
- High frequency rectification in switching mode converters
- Freewheeling applications in inverters
- Consumer electronics power supplies
- Computer equipment power systems
- Automotive electronic circuits
- Telecommunication infrastructure
Procurement Notes
Verify that the ordering suffix /97 corresponds to the specified delivery mode and base quantity. Confirm RoHS compliance status and material categorization definitions prior to procurement. Ensure the selected variant matches the required voltage rating within the BYM12 series range. Validate thermal resistance parameters against specific PCB pad layout requirements.
Selection Notes
Select this component when a single circuit configuration with a 400 V blocking voltage is required. The DO-213AB package is suitable for automated placement processes. Consider the 50 ns reverse recovery time for high-frequency switching applications where low switching losses are critical. Verify that the 1.0 A average forward current rating meets the load requirements at the expected ambient temperature.
Part Context
This part belongs to the BYM12-xxx series of surface-mount glass-passivated ultrafast rectifiers. The series covers voltage ratings from 50 V to 400 V, sharing identical mechanical and thermal characteristics. The EGL41x designation serves as an alternative identifier for the same product family. All variants utilize the GL41 (DO-213AB) case and maintain consistent performance metrics regarding surge current and recovery time.
Replacement Considerations
Cross-reference other BYM12-400 or EGL41G variants from Vishay for equivalent specifications. Verify package compatibility and pinout alignment before substitution. Ensure replacement parts meet the same RoHS and material categorization standards.
