1N5406G-K

Overview

The Taiwan Semiconductor Corporation 1N5406G-K is a standard recovery rectifier diode designed for general-purpose applications. It features a maximum average forward rectified current of 3 A and a maximum repetitive peak reverse voltage of 600 V. The device is housed in a DO-201AD (DO-27) through-hole package with axial leads. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 200 A, a maximum reverse current of 5 µA, and a maximum forward voltage of 1.2 V at rated current. It operates within a junction temperature range up to 150 °C.

Feature Summary

• High current capability with 3 A average forward rectified current rating
• Robust surge handling with 200 A peak forward surge current capacity
• Low leakage current ensuring efficient performance under reverse bias
• Flame-retardant molded epoxy body meeting UL 94V-0 flammability standards

Applications

• Single-phase diode rectification in power supplies
• Freewheeling diode applications in DC motor control and drives
• Battery chargers and welders
• Power converters and inverters
• Reverse polarity protection circuits

Procurement Notes

Verify the specific suffix against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging variations. Ensure the component meets RoHS compliance requirements if specified for your project. Cross-reference the DO-201AD package dimensions with your PCB footprint library to guarantee mechanical compatibility during assembly.

Selection Notes

Select this component for circuits requiring reliable 600 V blocking voltage and 3 A continuous current handling. It is suitable for standard frequency rectification where fast recovery is not critical. Consider the thermal management requirements for the DO-201AD package when designing high-current layouts. Verify that the 150 °C junction temperature rating aligns with your system's operating environment.

Part Context

This part belongs to the widely recognized 1N540x series of silicon rectifiers, offering standardized performance across various manufacturers. The G-K suffix indicates specific manufacturing lot or packaging details from Taiwan Semiconductor. It serves as a direct functional replacement for generic 1N5406 specifications in industrial and consumer electronics designs requiring robust, low-cost rectification solutions.

Replacement Considerations

Direct substitutes include Vishay 1N5406-E3/58 and Comchip Technology 1N5406-G. These alternatives share identical 3 A / 600 V ratings and DO-201AD packages. Verify pinout orientation and forward voltage drop similarities before finalizing substitutions in existing designs.
