1N5406-T

Overview

The Diodes Incorporated 1N5406-T is a standard recovery rectifier diode housed in a DO-201AD axial package. It features a maximum repetitive peak reverse voltage of 600 V and an average rectified output current of 3.0 A at 105°C ambient temperature. The device exhibits a forward voltage of 1.0 V at 3.0 A and a peak reverse current of 10 µA at rated DC blocking voltage. It supports a non-repetitive peak forward surge current of 200 A for 8.3 ms single half-sine-wave pulses. Operating and storage temperatures range from -65°C to +150°C.

Feature Summary

• Diffused junction construction providing high current capability and low forward voltage drop
• Surge overload rating capable of handling up to 200 A peak current
• Low reverse leakage current characteristics
• Lead-free finish compliant with RoHS standards

Applications

• General purpose rectification in power supplies
• Bridge rectifiers for AC to DC conversion
• Free-wheeling diodes in inductive load circuits

Procurement Notes

Verify the specific manufacturer lot and date code upon receipt, as this component is marked as not recommended for new design. Confirm that the DO-201AD package dimensions match your PCB footprint requirements. Ensure compliance with UL 94V-0 flammability ratings if required by your final equipment safety standards. Check for any updated replacement series recommendations from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a 600 V reverse voltage rating and 3.0 A continuous current capacity are required in an axial leaded package. Consider the thermal resistance of 15°C/W for heat dissipation calculations. Derate the forward current by 20% if used with capacitive loads. Verify that the standard recovery speed meets the switching frequency requirements of the target circuit application.

Part Context

This part belongs to the 1N5400 through 1N5408 series of general-purpose silicon rectifiers manufactured by Diodes Incorporated. The series shares identical mechanical data and electrical characteristics except for the specific reverse voltage ratings. The 1N5406 variant specifically provides the 600 V blocking capability within this lineup.

Replacement Considerations

The datasheet explicitly recommends using the S3A-S3M series as replacements. These alternative parts offer similar performance specifications while potentially addressing current manufacturing or supply chain updates associated with the legacy 1N5406 designation.
