1N5402RLG

Overview

The onsemi 1N5402RLG is an axial-lead glass-passivated standard recovery rectifier designed for power supply applications. It features a 200 V peak repetitive reverse voltage and a 3.0 A average rectified forward current rating. The device operates within a junction temperature range of -65°C to +150°C and withstands a non-repetitive peak surge current of 200 A. Packaged in the DO-201AD (Case 267-05) format, it offers low forward voltage drop and high surge current capability.

Feature Summary

• Glass passivation provides environmental protection and reliability
• High surge current capability supports transient load conditions
• Low forward voltage drop improves overall circuit efficiency
• Void-free plastic package meets UL 94 V-0 flammability standards

Applications

• General purpose rectification in power supplies
• Inverter circuits
• Converter applications
• Freewheeling diode usage

Procurement Notes

Verify that the ordering suffix RLG corresponds to the tape and reel packaging configuration rather than bulk box quantities. Confirm the specific device number matches the required voltage rating within the 1N540x series before finalizing procurement orders.

Selection Notes

Select this component when a 200 V blocking voltage and 3.0 A continuous current are required in an axial leaded form factor. Ensure thermal management accounts for the specified junction-to-ambient resistance values under expected operating loads.

Part Context

This part belongs to the 1N5400 through 1N5408 family of lead-mounted standard recovery rectifiers manufactured by onsemi. These devices share identical mechanical dimensions and current ratings, differing primarily in their maximum repetitive reverse voltage capabilities.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N5402 variants or equivalent parts from the 1N540x series with matching 200 V and 3.0 A specifications.
