6A8G

Overview

The 6A8G is a silicon rectifier diode manufactured by SMC Diode Solutions, designed for general-purpose applications. It features a maximum DC reverse voltage of 800 V and an average forward rectified current of 6 A. The component utilizes standard recovery technology with a reverse recovery time exceeding 500 ns. It exhibits a typical forward voltage drop of 1 V at 6 A and maintains low reverse leakage current of 10 µA at rated voltage. The device operates within a junction temperature range of -55°C to 150°C and is housed in the R-6 axial through-hole package.

Feature Summary

• High voltage blocking capability up to 800 V for robust circuit protection
• Standard recovery characteristics suitable for general-purpose rectification
• Wide operating temperature range ensuring reliability in extreme environments

Applications

• General-purpose power supply rectification
• AC to DC conversion circuits
• Industrial equipment power stages

Procurement Notes

Verify the manufacturer designation as SMC Diode Solutions or Micro Commercial Components (MCC) depending on the specific production lot, as both entities produce this part number. Confirm the R-6 axial leaded package style matches the board layout requirements. Ensure compliance with RoHS3 standards if required by the end product specifications. Check datasheet revisions for any updates to thermal resistance values.

Selection Notes

Select this component when a high-current, high-voltage rectifier with standard recovery speed is required. The 6 A rating supports moderate power loads, while the 800 V breakdown voltage handles significant line surges. The axial R-6 package facilitates easy manual insertion or wave soldering. Consider thermal management strategies given the 150°C junction limit and potential heat dissipation needs under continuous load conditions.

Part Context

The 6A8G belongs to the broader family of silicon rectifier diodes characterized by high voltage ratings and substantial current handling capabilities. It serves as a fundamental discrete semiconductor component in power electronics. Similar parts in this category include variants with different voltage ratings such as 6A2G or 6A10G, allowing designers to tailor voltage margins while maintaining consistent current and package specifications.
