1N4933GP

Overview

The onsemi 1N4933GP is a glass-passivated fast rectifier diode designed for high-efficiency switching applications. It features a maximum repetitive reverse voltage of 50 V and supports an average rectified forward current of 1.0 A at 75°C ambient temperature. The device exhibits a low forward voltage drop of 1.2 V at rated current and a reverse recovery time of 150 ns under specified test conditions. It provides a non-repetitive peak forward surge current capability of 30 A and operates within a junction temperature range of -65°C to +175°C.

Feature Summary

• Glass passivation for enhanced reliability
• Low forward voltage drop for efficiency
• High surge current capability

Applications

• Fast switching circuits
• High efficiency power supplies
• General purpose rectification

Procurement Notes

Verify the manufacturer designation, as Fairchild Semiconductor was acquired by onsemi. Confirm the specific ordering suffix matches the required package and tape/reel specifications. Ensure the component meets RoHS compliance requirements if applicable to your design constraints. Cross-reference the datasheet revision to confirm electrical characteristics align with current production standards.

Selection Notes

Select this component when a 50 V blocking voltage is sufficient for the application. Consider the 150 ns reverse recovery time for switching frequency limitations. Evaluate thermal management needs based on the 55 °C/W junction-to-ambient thermal resistance. Compare against higher voltage variants in the series if system transients exceed 50 V.

Part Context

This part belongs to the 1N4933GP through 1N4937GP series of fast rectifiers. The series shares identical physical packages and thermal characteristics while varying in maximum repetitive reverse voltage ratings from 50 V to 600 V. All devices utilize DO-41 axial leaded packaging and offer similar forward current capabilities.

Replacement Considerations

Direct substitutes include other manufacturers' 1N4933 equivalents. Verify that replacement parts maintain the 50 V rating and DO-41 package dimensions. Check reverse recovery time specifications to ensure compatibility with existing circuit timing requirements.
