Procurement Notes

Verify that the ordering suffix matches the required delivery mode and base quantity. Confirm RoHS compliance status and material categorization definitions prior to procurement. Ensure the selected variant aligns with specific thermal resistance requirements and mounting pad layouts for the target application environment.

Selection Notes

Select this component based on its 400 V reverse voltage rating and 1.0 A continuous current capacity. Evaluate the 150 ns reverse recovery time against circuit switching frequencies. Consider the DO-213AB package dimensions for automated placement compatibility and verify thermal management capabilities within the -65 °C to +175 °C operating range.

Part Context

This part belongs to the BYM11-xxx series of surface-mount fast switching rectifiers. The series offers various voltage ratings ranging from 50 V to 1000 V while maintaining consistent current handling and package specifications. The E3 suffix indicates RoHS compliance and lead-free construction, meeting JESD 201 class 1A whisker test standards.

Replacement Considerations

Compatible substitutes include other Vishay Superectifier devices such as RGL41J or RGL41G variants, provided they match the 400 V rating and DO-213AB footprint. Cross-referencing datasheets for identical reverse recovery times and forward voltage drops is essential for direct replacement.
