1N4933GP-E3/54

Overview

The Vishay 1N4933GP-E3/54 is a glass passivated junction fast switching plastic rectifier belonging to the SUPERECTIFIER series. It features a DO-41 (DO-204AL) axial leaded package and supports a maximum average forward rectified current of 1.0 A with a peak forward surge capability of 30 A. The device provides a maximum repetitive peak reverse voltage of 50 V, a maximum DC blocking voltage of 50 V, and a maximum RMS voltage of 35 V. Electrical characteristics include a maximum instantaneous forward voltage of 1.2 V at 1.0 A, a maximum reverse current of 5.0 μA at rated voltage, and a typical reverse recovery time of 200 ns. Operating temperatures range from -65 °C to +175 °C.

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm RoHS compliance status via the E3 suffix designation. Validate that the DO-41 package dimensions match required PCB footprints. Ensure thermal management aligns with specified junction temperature limits during operation.

Selection Notes

Select this component when a 50 V reverse voltage rating is required within the standard recovery family. Consider the 200 ns reverse recovery time for general-purpose fast switching needs. Evaluate the 1.0 A continuous current capacity against circuit load requirements. Verify compatibility with through-hole assembly processes given the axial lead configuration.

Part Context

This part belongs to the Vishay 1N493xGP series, which includes variants with different reverse voltage ratings up to 600 V. All members share identical physical packages and electrical parameters except for the maximum repetitive peak reverse voltage. The series utilizes the SUPERECTIFIER technology for enhanced reliability compared to standard rectifiers.

Replacement Considerations

Direct substitutes within the same Vishay family include 1N4934GP-E3/54, 1N4935GP-E3/54, 1N4936GP-E3/54, and 1N4937GP-E3/54. These alternatives offer higher reverse voltage ratings while maintaining identical current handling and package specifications.
