1N4933GP-M3/73

Overview

The Vishay 1N4933GP-M3/73 is a glass-passivated junction fast switching plastic rectifier designed for high reliability. It features a Superectifier structure with a cavity-free junction and matte tin-plated leads. The device provides a maximum average forward rectified current of 1.0 A and a repetitive peak reverse voltage of 50 V. 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. It supports a peak forward surge current of 30 A and operates within a junction temperature range of -65 °C to +175 °C.

Feature Summary

• Superectifier structure ensures high reliability under demanding conditions
• Cavity-free glass passivated junction enhances durability
• Fast switching capability improves efficiency in power circuits
• Low leakage current minimizes power loss

Applications

• Fast switching rectification in power supplies
• Inverter and converter circuits

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging type and compliance status. Confirm that the component meets RoHS requirements if applicable. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee authenticity. Check for any specific handling instructions related to the DO-41 package and lead solderability standards.

Selection Notes

Select this component when a standard fast recovery rectifier with low leakage is required. The 50 V rating suits low-voltage applications. Consider the thermal resistance and derating curves for high-temperature environments. Verify compatibility with existing PCB footprints for the DO-41 package. Evaluate the trade-off between switching speed and forward voltage drop for the specific circuit design.

Part Context

This part belongs to the 1N493xGP series of fast switching plastic rectifiers from Vishay General Semiconductor. The series includes variants with different reverse voltage ratings (1N4933 through 1N4937). These components are designed as replacements for standard silicon rectifiers where faster recovery times are beneficial. The GP designation indicates the Superectifier technology used in the construction.

Replacement Considerations

Direct substitutes include other 1N4933 variants from Vishay with different packaging codes, such as 1N4933GP-E3/54. Cross-brand replacements must match the 1.0 A current rating, 50 V reverse voltage, and 200 ns reverse recovery time specifications.
