1N5406RL

Overview

The onsemi 1N5406RL is an axial-lead standard recovery rectifier designed for power supply applications. It features a maximum average rectified forward current of 3.0 Amperes and a peak repetitive reverse voltage of 600 Volts. The device operates within a junction temperature range of -65 to +170°C and withstands a non-repetitive peak surge current of 200 Amperes. Electrical characteristics include a maximum forward voltage of 1.0 Volt at 3.0 Amps and a reverse leakage current of up to 100 μA at 150°C. The component utilizes a molded epoxy plastic package compliant with UL 94V-0 flammability standards.

Feature Summary

• High current capability relative to physical size
• Low forward voltage drop for efficiency
• High surge current capability for transient protection
• Void-free economical plastic package construction

Applications

• Power supplies
• General purpose rectification
• Standard recovery circuits

Procurement Notes

Verify the specific ordering suffix RL indicates tape and reel packaging configuration rather than bulk box quantities. Confirm that the part number corresponds to the 1N5406 voltage rating variant within the series. Ensure compatibility with automated surface mount or through-hole assembly processes requiring reel-fed components. Cross-reference the marking diagram for correct polarity band identification during inspection.

Selection Notes

Select this component when a 600 Volt blocking capability is required alongside a 3.0 Ampere continuous current rating. Consider the thermal resistance characteristics and lead length options for optimal heat dissipation in the target circuit layout. Evaluate the standard recovery speed against application frequency requirements to ensure adequate performance without unnecessary switching losses.

Part Context

This device belongs to the 1N5400 through 1N5408 series of axial-lead standard recovery rectifiers manufactured by onsemi. The series offers varying reverse voltage ratings from 50 to 1000 Volts while maintaining a consistent 3.0 Ampere current handling capacity. The 1N5406 variant specifically provides a 600 Volt rating, positioned between the 1N5404 (400V) and 1N5407 (800V) models in the lineup.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N5406 diodes meeting identical electrical specifications. Verify mechanical dimensions match Case 267-05 standards for direct replacement. Ensure equivalent thermal resistance and surge current ratings are maintained in alternative sourcing decisions.
