6A4-T

6A4-T Description

The 6A4-T from Diodes Incorporated is a standard recovery rectifier diode designed for general-purpose applications requiring robust performance and reliability. With a maximum reverse voltage (Vr) of 400V and an average rectified current (Io) of 6A, this through-hole-mounted diode is engineered for efficiency in medium-power circuits. Its low forward voltage drop (900mV @ 6A) ensures minimal power loss, while the reverse leakage current of just 10µA @ 400V enhances energy efficiency. Packaged in a Tape & Reel (TR) format, the 6A4-T is RoHS3 compliant and adheres to REACH regulations, making it suitable for environmentally conscious designs.

6A4-T Features

• High Voltage & Current Handling: Supports 400V reverse voltage and 6A average rectified current, ideal for demanding applications.
• Low Power Dissipation: 900mV forward voltage drop minimizes heat generation, improving system efficiency.
• Standard Recovery Speed: Recovery time >500ns at >200mA, balancing performance and cost for general-purpose use.
• Robust Packaging: Through-hole mounting ensures mechanical stability, while Tape & Reel packaging facilitates automated assembly.
• Compliance & Reliability: RoHS3 compliant, REACH affected, and MSL 1 (Unlimited) rated for long-term storage and handling flexibility.

6A4-T Applications

The 6A4-T excels in power supply rectification, AC/DC converters, and bridge rectifiers due to its high voltage and current capabilities. It is particularly suited for:

• Industrial Power Systems: Where reliability under medium-load conditions is critical.
• Consumer Electronics: Such as SMPS (Switched-Mode Power Supplies) and battery chargers, leveraging its low forward voltage for energy efficiency.
• Automotive Auxiliary Circuits: Non-critical systems requiring stable rectification.
• Renewable Energy Systems: Including solar inverters, where low leakage and high voltage tolerance are advantageous.

Conclusion of 6A4-T

The 6A4-T stands out as a cost-effective, high-performance rectifier diode for general-purpose applications. Its combination of 400V blocking capability, 6A current handling, and low forward voltage makes it a versatile choice for designers prioritizing efficiency and reliability. While obsolete, its proven performance in industrial, consumer, and automotive systems ensures it remains a viable option for legacy designs or replacements. For engineers seeking a balance of performance, compliance, and ease of integration, the 6A4-T delivers a compelling solution.
