1N456A_T50R

Overview

The onsemi 1N456A_T50R is a general-purpose standard recovery rectifier diode designed for through-hole mounting. It features a maximum DC reverse voltage of 30 V and an average rectified forward current of 500 mA. The device utilizes a DO-35 axial leaded package, measuring approximately 4.06 mm in length and 1.91 mm in height. It operates within a temperature range of -65°C to +200°C junction temperature. The component exhibits a maximum forward voltage of 1 V at a forward current of 100 mA and provides standard recovery characteristics with a reverse recovery time exceeding 500 ns.

Feature Summary

• Standard recovery performance suitable for general-purpose rectification applications
• Robust thermal capability with a maximum operating junction temperature of 200°C
• Compact axial DO-35 package facilitating automated insertion and manual assembly

Applications

• General-purpose rectification in low-voltage power supplies
• Protection circuits requiring 30 V reverse blocking capability
• Signal demodulation in consumer electronics

Procurement Notes

Verify the obsolete status and end-of-life designation before finalizing designs. Confirm that the DO-35 package dimensions and electrical parameters meet specific circuit requirements. Check for available alternative sources or equivalent components from other manufacturers if long-term supply stability is required for production.

Selection Notes

Select this component when a 30 V reverse voltage rating and 500 mA continuous current capacity are sufficient for the application. Consider the standard recovery speed for non-switching or low-frequency applications. Ensure the PCB layout accommodates the axial leads and thermal dissipation needs of the DO-35 package under expected load conditions.

Part Context

This part belongs to the legacy 1N45xx series of silicon planar junction rectifiers manufactured by onsemi. These components were widely used in older electronic designs requiring reliable general-purpose rectification. The T50R suffix typically indicates specific tape-and-reel packaging configurations for automated manufacturing processes.

Replacement Considerations

• 1N4001 (Generic equivalent with higher voltage rating)
• 1N5392 (Similar current rating but different package)
