Overview
The Vishay 1N4937-E3/54 is a fast switching plastic rectifier featuring a single circuit configuration in a DO-204AL (DO-41) package. It supports a maximum repetitive peak reverse voltage of 600 V and a maximum average forward rectified current of 1.0 A at 75 °C ambient temperature with a 0.375-inch lead length. The device exhibits a maximum instantaneous forward voltage of 1.2 V, a peak forward surge current capability of 30 A, and a maximum reverse recovery time of 200 ns. Operating junction temperatures range from -50 °C to +150 °C.
Feature Summary
- Fast switching performance for high efficiency applications
- Low forward voltage drop and low leakage current characteristics
- High forward surge current capability
- Molded epoxy body meeting UL 94 V-0 flammability rating
Applications
- Fast switching rectification in power supplies
- Inverter and converter circuits
- Freewheeling diodes for consumer electronics
- Telecommunication equipment
Procurement Notes
Verify the specific ordering suffix /54 corresponds to the 13-inch diameter paper tape and reel delivery mode with a base quantity of 5500 units. Confirm RoHS compliance status as indicated by the E3 designation. Ensure technical parameters are validated against the official datasheet for the intended application environment.
Selection Notes
Select this component for designs requiring fast recovery characteristics within a standard through-hole axial package. Evaluate thermal resistance requirements based on the specified junction-to-ambient and junction-to-lead ratings. Consider the 600 V reverse voltage rating relative to the system's peak inverse voltage demands.
Part Context
This part belongs to the 1N4933 through 1N4937 series of fast switching plastic rectifiers manufactured by Vishay General Semiconductor. The series shares identical electrical characteristics except for the maximum repetitive peak reverse voltage, which varies across the range from 50 V to 600 V.
Replacement Considerations
Direct substitutes include other 1N4937 variants such as 1N4937GP-E3/54 or generic equivalents matching the DO-41 package, 1 A current rating, and 600 V reverse voltage specifications.
