6A4

Overview

The MCC 6A4 is a standard silicon rectifier diode designed for general-purpose applications. It features a maximum average forward rectified current of 6.0 A and a maximum repetitive peak reverse voltage of 400 V. The device utilizes an R-6 axial leaded package with a molded plastic body rated UL 94 V-0. Electrical characteristics include a typical junction capacitance of 150 pF at 1.0 MHz, a maximum DC reverse leakage current of 10 µA at rated blocking voltage, and a peak forward surge current capability of 400 A for an 8.3 ms half-sine wave pulse.

Feature Summary

• High current capability combined with low forward voltage drop
• Low reverse leakage current across operating temperatures
• Epoxy casing meets UL 94 V-0 flammability rating
• Guaranteed high temperature soldering performance

Applications

• General purpose rectification in power supplies
• Bridge rectifier configurations
• Free-wheeling diodes in inductive load circuits
• Polarity protection in electronic devices

Procurement Notes

Verify the specific ordering suffix to confirm packaging type and compliance status. The -TP suffix indicates tape and reel packaging, while -BP denotes bulk packing. Ensure the selected variant matches the required halogen-free or RoHS compliance specifications by checking the manufacturer's official ordering guide before finalizing procurement orders.

Selection Notes

Select this component when a 6 A continuous current rating and 400 V reverse voltage are required in an axial through-hole package. Consider the thermal resistance of 10°C/W and derating curves for ambient temperature conditions. Verify that the standard recovery speed meets the circuit requirements, as it is not optimized for high-frequency switching applications.

Part Context

The 6A4 belongs to the 6A series of rectifiers from Micro Commercial Components, covering voltage ratings from 50 V to 1000 V. This family shares common mechanical dimensions and electrical characteristics scaled by voltage rating. The R-6 package provides a standardized footprint for PCB mounting or chassis installation in various industrial and consumer electronics designs.

Replacement Considerations

Direct substitutes must match the 6 A current rating, 400 V reverse voltage, and R-6 axial package. Verify equivalent forward voltage drop and reverse leakage specifications to ensure circuit compatibility without redesign.
