6A4

Overview

The SMC Diode Solutions 6A4 is a general-purpose standard recovery rectifier diode designed for through-hole mounting. It features an R-6 axial leaded package and supports a maximum repetitive peak reverse voltage of 400 V with an average rectified forward current rating of 6 A. The device exhibits a typical forward voltage drop of 1.1 V at the rated current and maintains a low reverse leakage current of 5 µA at full reverse voltage. Operating junction temperatures range from -55°C to +175°C, ensuring reliability in demanding thermal environments.

Feature Summary

• High thermal stability with extended operating junction temperature range up to 175°C
• Robust mechanical construction utilizing the durable R-6 axial leaded package
• Low forward voltage drop characteristics for improved power efficiency
• Minimal reverse leakage current under maximum rated reverse voltage conditions

Applications

• General purpose rectification in AC/DC power supply circuits
• Bridge rectifier configurations for mains voltage conversion
• Freewheeling diodes in inductive load switching applications
• Polarity protection circuits in DC power distribution systems

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as 6A4G may exist with distinct packaging or handling specifications. Confirm that the required package type matches the target PCB footprint, specifically the R-6 axial form factor. Ensure the selected component meets all necessary regulatory compliance standards for the intended end-use market before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring high current handling capabilities within a robust through-hole configuration. The 175°C junction temperature rating allows for operation in higher ambient temperature environments compared to standard 150°C devices. Consider the physical size constraints of the R-6 package during layout planning to ensure adequate clearance and mechanical stability.
