Procurement Notes
Verify the specific part number against official Vishay documentation to confirm compliance with RoHS standards and material categorization requirements. Ensure that the ordering suffix matches the required delivery mode and package code. Cross-reference technical parameters such as thermal resistance and lead length specifications with the latest datasheet revision before finalizing procurement orders.
Selection Notes
Select this component when applications require fast switching capabilities combined with low forward voltage drop and low leakage current. The device is suitable for circuits demanding high forward surge capability within a DO-41 through-hole package. Verify that the operating temperature range and electrical ratings align with the specific design constraints of the target application.
Part Context
This component belongs to the 1N493x series of fast switching plastic rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different reverse voltage ratings, sharing common mechanical and electrical characteristics such as the DO-41 molded epoxy body and matte tin plated leads. The E3 designation indicates RoHS compliance and halogen-free construction.
Replacement Considerations
Compatible substitutes include other Vishay 1N493x series rectifiers with matching or higher voltage ratings, such as the 1N4933, 1N4935, 1N4936, and 1N4937. Ensure that any replacement maintains the same package type and meets the required electrical specifications for forward current, reverse voltage, and recovery time.
