Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging specifications. Ensure compliance with RoHS directives and halogen-free requirements as stated in the component documentation. Cross-reference the package type E-LALF-W2 with your PCB footprint design to guarantee mechanical compatibility before finalizing procurement orders.

Selection Notes

Select this component when a 3 A continuous current rating and 400 V blocking voltage are required for fast recovery applications. Consider the hermetic glass construction if environmental sealing is critical. Evaluate the avalanche capability requirement against the circuit's inductive energy levels to ensure adequate safety margins during transient events.

Part Context

This part belongs to the Vishay general semiconductor diode portfolio, specifically categorized under fast recovery rectifiers. It utilizes a two-terminal glass-encapsulated configuration typical for through-hole mounting. The component serves as a discrete solution for converting alternating current to direct current in medium-power electronic systems requiring reliable switching performance.

Replacement Considerations

Consult official Vishay substitution guides for compatible alternatives. Verify that any substitute matches the 3 A current rating, 400 V reverse voltage, and fast recovery time specifications. Ensure the replacement package maintains identical pinout and thermal characteristics for direct board integration.
