6A40GH

Overview

The Taiwan Semiconductor 6A40GH is a standard recovery rectifier diode designed for general-purpose applications. It features an average forward current rating of 6 amperes and a repetitive peak reverse voltage capability of 400 volts. The device utilizes a glass-passivated junction construction to ensure stability under various operating conditions. It is housed in the DO-201AD (DO-204AC) axial leaded package, which provides robust mechanical support and efficient heat dissipation for through-hole mounting configurations.

Feature Summary

• Glass-passivated junction construction for enhanced environmental stability
• High surge current handling capability for transient protection
• Low forward voltage drop characteristics for improved efficiency

Applications

• General-purpose rectification in power supply circuits
• Freewheeling diodes in inductive load switching
• Polarity protection in DC input lines

Procurement Notes

Verify the specific suffix 'H' against the manufacturer's official datasheet to confirm if it denotes a specific tape-and-reel variant or packaging option distinct from the standard 'G' version. Ensure the component matches the required DO-201AD footprint and pin configuration for your PCB design before finalizing procurement.

Selection Notes

Select this component when a 6A current capacity and 400V blocking voltage are required in an axial package. Consider the reverse recovery time specifications if used in high-frequency switching applications, as standard recovery diodes may exhibit higher losses compared to fast recovery types at elevated frequencies.

Part Context

This part belongs to the family of high-current axial rectifiers manufactured by Taiwan Semiconductor. It serves as a robust solution for medium-power AC-to-DC conversion tasks. The DO-201AD package allows for easy integration into legacy designs and industrial equipment requiring reliable through-hole rectification with substantial current carrying capabilities.

Replacement Considerations

Direct substitutes include other 6A 400V standard recovery diodes in the DO-201AD package, such as those from Vishay or Littelfuse. Verify that any replacement maintains identical pinout, thermal resistance, and reverse recovery characteristics to ensure circuit compatibility.
