1N4933GP-E3/73

Overview

The 1N4933GP-E3/73 is a glass-passivated junction fast switching plastic rectifier manufactured by Vishay General Semiconductor - Diodes Division. It belongs to the Superectifier series and features a DO-41 (DO-204AL) axial through-hole package. The device provides a maximum repetitive peak reverse voltage of 50 V, an average forward rectified current of 1.0 A, and a peak forward surge current of 30 A. Key electrical characteristics include a maximum instantaneous forward voltage of 1.2 V at 1.0 A, a maximum DC reverse current of 5.0 μA at rated blocking voltage, and a typical reverse recovery time of 200 ns.

Feature Summary

• Superectifier structure designed for high reliability under demanding conditions
• Cavity-free glass passivated junction construction
• Fast switching capability optimized for high efficiency applications
• Low leakage current performance across operating temperatures

Applications

• Fast switching rectification in power supplies
• Inverter circuits
• Converter systems
• Freewheeling diodes for consumer electronics
• Telecommunication equipment

Procurement Notes

Verify component authenticity against official Vishay documentation before integration. Confirm that the specific ordering suffix matches the required packaging format. Ensure compliance with RoHS standards and material categorization requirements as defined in the datasheet. Validate thermal resistance parameters for your specific mounting configuration.

Selection Notes

Select this component when a 50 V reverse voltage rating is required alongside fast switching speeds. The Superectifier structure offers enhanced reliability compared to standard rectifiers. Consider the DO-41 package dimensions and lead length specifications for PCB layout compatibility. Evaluate the 200 ns reverse recovery time against circuit frequency requirements.

Part Context

This part is part of the 1N4933GP through 1N4937GP family, differentiated primarily by their maximum repetitive peak reverse voltage ratings ranging from 50 V to 600 V. All members share identical physical packages, current ratings, and switching characteristics. The E3 suffix indicates RoHS compliance and matte tin-plated leads suitable for solderability per J-STD-002.

Replacement Considerations

Direct substitutes within the same Vishay family include parts with higher voltage ratings such as 1N4934GP or 1N4935GP, provided the lower voltage rating does not compromise safety margins. Cross-manufacturer replacements must match the 50 V reverse voltage, 1.0 A forward current, and DO-41 package constraints.
