1N6674

Overview

The Microchip Technology 1N6674 is a standard rectifier diode designed for general-purpose applications. It features a maximum DC reverse voltage of 500 V and an average forward rectified current of 15 A. The device utilizes a TO-254 (DPAK) through-hole package, suitable for surface or panel mounting. Key electrical characteristics include a maximum forward voltage of 1.35 V at 10 A and a reverse leakage current of 50 µA at 400 V. The junction temperature range spans from -55°C to +175°C, ensuring reliability in demanding thermal environments.

Feature Summary

• High current handling capability with a 15 A average forward rectified current rating.
• Robust voltage blocking performance supporting up to 500 V DC reverse voltage.
• Extended thermal stability allowing operation across a wide junction temperature range.

Applications

• General-purpose power supply rectification
• Industrial equipment power stages
• Automotive electronics systems

Procurement Notes

Verify the specific suffix variant when ordering, as packaging and compliance status may differ. Confirm RoHS compliance requirements against project specifications, as standard variants may not meet all environmental directives. Cross-reference the manufacturer datasheet for exact mechanical dimensions and pinout configurations to ensure compatibility with existing PCB footprints and assembly processes.

Selection Notes

Select this component for circuits requiring high surge current tolerance and reliable rectification at moderate frequencies. Evaluate the thermal management strategy, as the TO-254 package dissipates heat primarily through the exposed pad. Ensure the operating ambient temperature remains within the specified limits to maintain the rated current capacity without derating.

Part Context

This part belongs to the legacy 1N series rectifier family, widely adopted in industrial and automotive sectors. It serves as a robust solution for converting AC to DC in power distribution networks. The TO-254 package offers a balance between current capacity and board space efficiency compared to larger axial leads.
