AL01V

Overview

The AL01V is a fast recovery diode manufactured by Sanken Electric USA Inc. It features a maximum repetitive peak reverse voltage (V_RM) of 200 V and an average forward current (I_F(AV)) rating of 0.5 A. The device achieves a maximum reverse recovery time (t_rr) of 400 ns through optimized lifetime control techniques. Key electrical parameters include a typical forward voltage (V_F) of 1.7 V at the rated current. The component is supplied in an axial package with bare leads that are lead-free and RoHS compliant, suitable for surface or through-hole mounting depending on the specific circuit board design.

Feature Summary

• Fast recovery characteristics achieved via optimized lifetime control
• Lead-free construction compliant with RoHS standards
• Axial package configuration with bare leads

Applications

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

Procurement Notes

Verify the exact part number against official Sanken Electric documentation to ensure correct specifications. Confirm package dimensions and lead compatibility with your PCB layout. Check for any specific ordering suffixes that may indicate variations in packaging or tape-and-reel options. Ensure compliance with local environmental regulations regarding lead-free components.

Selection Notes

Select this component for applications requiring fast switching speeds with moderate current handling capabilities. The 200 V rating suits low-voltage power supply designs. Consider the thermal management requirements associated with the axial package. Verify that the 400 ns reverse recovery time meets the efficiency targets of the target converter topology.

Part Context

This component belongs to the category of fast recovery diodes designed for general-purpose power conversion. It is distinct from standard rectifier diodes due to its optimized reverse recovery characteristics. The product line focuses on providing reliable performance in compact power supply architectures where switching losses need to be minimized.

Replacement Considerations

Consult official Sanken Electric substitution guides for verified alternatives. Ensure any replacement matches the 200 V reverse voltage and 0.5 A current ratings. Verify that the substitute component offers comparable reverse recovery time and forward voltage characteristics to maintain circuit performance.
