1N5401RLG

Overview

The onsemi 1N5401RLG is an axial-lead glass-passivated standard recovery rectifier designed for power supply applications. It features a maximum average forward rectified current of 3.0 A and a peak repetitive reverse voltage of 100 V. The device supports a non-repetitive peak surge current of 200 A and operates within a junction temperature range of -65°C to +150°C. Electrical characteristics include a maximum forward voltage of 1.0 V at 3.0 A and a maximum reverse current of 10 μA at rated DC voltage and 25°C.

Feature Summary

• High surge current capability
• Low forward voltage drop
• Void-free economical plastic package

Applications

• Power supplies
• General-purpose rectification

Procurement Notes

Verify the specific ordering suffix 'RLG' against official documentation to confirm tape and reel packaging specifications, including part orientation and tape size. Ensure compliance with RoHS requirements as indicated by the manufacturer's lead-free strategy. Cross-reference the document number 1N5400/D for accurate mechanical dimensions and thermal resistance data before finalizing procurement.

Selection Notes

Select this component for circuits requiring a 3.0 A continuous current rating with a 100 V blocking voltage. Consider the thermal resistance of 53 °C/W when designing heat dissipation strategies. Verify that the operating environment stays within the specified -65°C to +150°C junction temperature range. Derate current by 20% if used with capacitive loads.

Part Context

This device belongs to the 1N5400 through 1N5408 series of axial-lead standard recovery rectifiers. These components are manufactured in a DO-201AD (Case 267-05) package. The series covers reverse voltage ratings from 50 V to 1000 V while maintaining a consistent 3.0 A average forward current capability across all variants.
