Overview
The Vishay General Semiconductor 1N4935-E3/54 is a fast switching plastic rectifier featuring a single silicon junction in a DO-41 (DO-204AL) molded epoxy package. It supports a maximum average forward rectified current of 1.0 A and a peak forward surge current of 30 A. The device provides a maximum repetitive peak reverse voltage of 200 V, with a maximum instantaneous forward voltage of 1.2 V and a maximum DC reverse current of 5.0 μA at rated blocking voltage. The typical reverse recovery time is 200 ns, and the operating junction temperature range extends from -50 °C to +150 °C.
Feature Summary
- Fast switching capability for high efficiency applications
- Low forward voltage drop and low leakage current
- High forward surge capability
- Matte tin plated leads solderable per J-STD-002
Applications
- Fast switching rectification of power supplies
- Inverter and converter circuits
- Freewheeling diodes for consumer electronics
- Telecommunication equipment
Procurement Notes
Verify that the ordering suffix /54 corresponds to the specified delivery mode of 13-inch diameter paper tape and reel packaging. Confirm RoHS compliance via the E3 suffix designation. Ensure the component meets the required thermal resistance ratings for the specific ambient temperature conditions of the target application before finalizing procurement.
Selection Notes
Select this component when a 200 V reverse voltage rating is required alongside fast switching performance. The DO-41 through-hole package is suitable for general-purpose circuit board mounting. Verify that the 1.0 A continuous current rating aligns with the load requirements and that the 200 ns reverse recovery time meets the frequency specifications of the intended switching application.
Part Context
This part belongs to the 1N493x series of 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 members share identical mechanical dimensions, current ratings, and switching characteristics, differing only in their maximum repetitive peak reverse voltage capabilities.
Replacement Considerations
Compatible substitutes include other manufacturers' 1N4935 equivalents or Vishay's 1N4935E-E3/54 variant. Verify that replacement parts maintain the same DO-41 package outline, 200 V reverse voltage rating, and 200 ns reverse recovery time to ensure direct interchangeability without circuit redesign.
