AG01

Overview

The AG01 is a fast recovery diode manufactured by Sanken Electric USA Inc. It features a maximum repetitive peak reverse voltage (VRM) of 400 V and an average forward current (IF(AV)) rating of 0.7 A. The device achieves a maximum reverse recovery time (trr) of 100 ns through optimized lifetime control. Key electrical characteristics include a forward voltage drop (VF) of 1.8 V at 0.7 A and a reverse leakage current (IR) of 100 µA at VRM. The component operates within a junction temperature range of -40 °C to 150 °C and utilizes an axial package with bare leads compliant with RoHS standards.

Feature Summary

• Optimized lifetime control enables a fast reverse recovery time of up to 100 ns.
• Axial package design with bare leads that are lead-free and RoHS compliant.
• High thermal stability supporting operation across a wide junction temperature range.

Applications

• Secondary-side rectifier diodes in flyback converters
• Secondary-side rectifier diodes in LLC converters
• Freewheel diodes in offline buck converters
• Freewheel diodes in offline buck-boost converters

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation, as suffixes may indicate variations in packaging or taping specifications rather than functional differences. Confirm compliance requirements such as RoHS status and flammability ratings (UL94V-0 equivalent) prior to integration. Ensure that the selected variant matches the required axial package dimensions and lead specifications for your assembly process.

Selection Notes

Select this component for circuits requiring a 400 V blocking capability and 0.7 A continuous current handling. The 100 ns reverse recovery time makes it suitable for high-frequency switching applications like flyback and LLC topologies. Consider the thermal resistance and derating curves when designing for elevated ambient temperatures to ensure the junction temperature remains within the specified -40 °C to 150 °C operating range.

Part Context

The AG01 belongs to the AG01 series of fast recovery diodes produced by Sanken Electric. This series is designed for general-purpose electronic equipment, including home appliances and office machinery. The device represents a standard axial-leaded discrete semiconductor solution optimized for efficiency and reliability in power conversion stages where moderate speed and voltage ratings are required.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing designs by matching key parameters: 400 V reverse voltage, 0.7 A average forward current, and similar reverse recovery time specifications.
