1N5405

Overview

The onsemi 1N5405 is a silicon rectifier diode designed for general-purpose applications. It features a single-phase, one-element configuration housed in the DO-201AD plastic axial lead package. The device supports a maximum average forward rectified current of 3 A and offers a repetitive peak reverse voltage rating of 500 V. It operates within a junction temperature range of -50 °C to 150 °C and can withstand a non-repetitive peak forward surge current of 200 A.

Feature Summary

• Utilizes glass passivated junction technology to ensure stable electrical performance under varying conditions.
• Engineered with low leakage current characteristics to minimize power loss during reverse bias states.
• Features high surge current capability suitable for handling transient load spikes.

Applications

• General purpose rectification in power supply circuits
• Free wheeling diode applications in inductive loads
• DC output rectification in AC-to-DC converters

Procurement Notes

Verify the specific manufacturer suffix or lot code against official datasheets to confirm compliance with the 500 V reverse voltage rating and 3 A current capacity. Ensure the component matches the DO-201AD package dimensions and lead configuration required by the design. Cross-reference part markings with authorized distributor catalogs to authenticate origin and avoid counterfeit components.

Selection Notes

Select this component when a robust standard recovery diode is required for medium-power rectification tasks. The 500 V blocking voltage provides sufficient margin for common mains-derived voltages. The DO-201AD package facilitates through-hole mounting, making it suitable for prototyping and industrial equipment where mechanical stability is prioritized over miniaturization.

Part Context

This component belongs to the widely recognized 1N54xx series of silicon rectifier diodes. These devices are industry-standard replacements for legacy designs requiring reliable unidirectional current flow. The 1N5405 specifically denotes the 500 V variant within this family, sharing identical thermal and mechanical characteristics with its lower and higher voltage counterparts.

Replacement Considerations

Compatible substitutes include the UF5405 from Continental Device India Limited and the 1N5406 from Gulf Semiconductor, provided the voltage ratings meet circuit requirements. Verify that alternative sources maintain the same DO-201AD footprint and 3 A current handling capabilities.
