1N4933GPHE3/73

Overview

The Vishay 1N4933GP-E3/73 is a glass passivated junction fast switching plastic rectifier designed for high reliability. It features a Superectifier structure and cavity-free construction within a DO-41 (DO-204AL) axial package. The device supports 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 maximum reverse recovery time of 200 ns. The component operates across a temperature range of -65 °C to +175 °C.

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging type and compliance status. The /73 suffix indicates ammo pack packaging with a base quantity of 3000 units. Confirm RoHS compliance and material categorization details via the manufacturer's documentation before procurement. Ensure lead length requirements match application constraints.

Selection Notes

Select this component for applications requiring fast switching performance and high reliability in compact axial packages. The 50 V reverse voltage rating suits low-voltage rectification tasks. Verify thermal resistance and derating curves for ambient temperature conditions. Consider the 200 ns reverse recovery time for frequency compatibility. Validate junction capacitance requirements for signal integrity.

Part Context

This part belongs to the Vishay 1N4933GP through 1N4937GP series of glass passivated junction fast switching plastic rectifiers. The series shares common mechanical and thermal characteristics while varying in reverse voltage ratings from 50 V to 600 V. All variants utilize the DO-41 (DO-204AL) package and feature the Superectifier structure for enhanced durability and consistent performance across different voltage classes.

Replacement Considerations

Direct substitutes within the same Vishay series include 1N4934GP, 1N4935GP, 1N4936GP, and 1N4937GP, which share identical package and current ratings but offer higher reverse voltage capabilities. Cross-brand replacements must match the 1.0 A current, 50 V reverse voltage, and DO-41 package dimensions.
