Procurement Notes

Verify that the specific ordering suffix matches the required packaging configuration, as standard delivery may vary from bulk or taping specifications. Confirm compliance with export control regulations such as EAR99 before finalizing procurement. Ensure the component is sourced directly from authorized channels to guarantee authenticity and access to the latest datasheet revisions.

Selection Notes

Select this component for circuits requiring high-speed switching capabilities where low reverse recovery charge is critical. Evaluate the derating curves for average forward current against the expected lead temperature to ensure safe operation. Consider the thermal resistance between the junction and the lead when designing heat dissipation strategies for the target application environment.

Part Context

The AG01A belongs to the general-purpose fast recovery diode series produced by Sanken Electric. It is designed for use in power supply applications requiring efficient rectification and minimal switching losses. The product line emphasizes reliability and performance in compact axial packages suitable for through-hole mounting on printed circuit boards.

Replacement Considerations

Ensure any substitute part maintains equivalent electrical ratings, specifically a minimum 600 V reverse voltage and comparable reverse recovery time. Verify that the replacement package dimensions match the existing footprint to avoid mechanical interference during assembly.

FAQ

What is the maximum reverse recovery time specified for the AG01A?

The maximum reverse recovery time (trr) is 100 ns under standard test conditions at a junction temperature of 25 °C.

How does the junction temperature affect the forward voltage drop?

The forward voltage drop decreases as the junction temperature increases; it is typically 1.1 V at 100 °C compared to 1.8 V at 25 °C.
