Overview
The Vishay 1N4937GPE-E3/91 is a glass passivated junction fast switching plastic rectifier. It features a Superectifier structure for high reliability and cavity-free construction. The device provides a maximum repetitive peak reverse voltage of 600 V and an average forward rectified current of 1.0 A. Key electrical characteristics include a maximum instantaneous forward voltage of 1.2 V, a maximum DC reverse current of 5.0 μA at rated blocking voltage, and a typical reverse recovery time of 200 ns. It supports a peak forward surge current of 30 A and operates within a junction temperature range of -65 to +175 °C.
Feature Summary
- Glass passivated junction with cavity-free construction for enhanced reliability
- Superectifier structure designed for high efficiency fast switching applications
- Low leakage current and high forward surge capability
Applications
- Fast switching rectification in power supplies
- Inverter and converter circuits
- Freewheeling diodes for consumer electronics
- Telecommunication equipment
Procurement Notes
Verify the specific suffix /91 against official documentation to confirm packaging details, as standard datasheets list /54 (Reel) and /73 (Ammo pack). Confirm RoHS compliance status and check for 'Not for New Designs' restrictions before finalizing procurement plans.
Selection Notes
Select this component for applications requiring 600 V reverse voltage and 1 A continuous current handling. Ensure the circuit design accommodates the 200 ns reverse recovery time and 1.2 V forward voltage drop. Verify thermal management requirements given the 175 °C maximum junction temperature rating.
Part Context
This part belongs to the 1N493xGP series of glass passivated junction fast switching plastic rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different reverse voltage ratings ranging from 50 V to 600 V, all sharing similar mechanical and electrical characteristics.
Replacement Considerations
Compatible substitutes within the same family include 1N4933GP through 1N4936GP, provided their lower reverse voltage ratings meet the application requirements.
