AL01Z

Overview

The AL01Z is a fast recovery diode manufactured by Sanken Electric USA Inc. It features a maximum repetitive reverse voltage (VRM) of 200 V and an average forward current (IF(AV)) rating of 1.0 A. The device achieves a maximum reverse recovery time (trr) of 50 ns through optimized lifetime control. Electrical characteristics include a maximum forward voltage drop (VF) of 0.98 V at 1.0 A and a maximum reverse leakage current (IR) of 50 µA at VRM. The component operates within a junction temperature range of -40 °C to 150 °C and utilizes a lead-free axial package.

Procurement Notes

Verify the specific datasheet revision prior to procurement, as Sanken Electric may update product information without notice. Confirm that the component meets all applicable environmental regulations, such as the EU RoHS Directive, regarding controlled substances. Ensure that the design accounts for derating requirements and safety margins appropriate for the intended operating conditions.

Selection Notes

Select the AL01Z when a fast recovery characteristic is required for general-purpose rectification or switching applications up to 200 V. Consider the thermal resistance between the junction and the lead when designing heat dissipation strategies. Evaluate the surge forward current capability against potential transient loads to ensure reliable operation under peak conditions.

Part Context

The AL01Z belongs to Sanken Electric's discrete semiconductor portfolio, specifically designed for power conversion circuits. It serves as a specialized component for high-frequency switching environments where rapid recovery times are critical. The manufacturer provides comprehensive technical documentation detailing absolute maximum ratings and electrical characteristics to support circuit design integration.

Replacement Considerations

The datasheet explicitly states that the AL01Z is not recommended for new designs. Engineers should consult Sanken Electric sales representatives to identify suitable alternative components that meet current design guidelines and availability requirements.

FAQ

What is the maximum reverse recovery time specified for the AL01Z?

The maximum reverse recovery time (trr) is 50 ns, measured at TJ = 25 °C with IF = IRP = 100 mA at the 90% recovery point.

Is the AL01Z suitable for use in aerospace or nuclear power control systems?

No. The datasheet specifies that the product is not intended for applications requiring extremely high reliability, such as aerospace equipment or nuclear power control systems.

What is the maximum non-repetitive surge forward current rating?

The surge forward current (IFSM) rating is 25 A, based on a half-cycle sine wave, positive side, for 10 ms duration in a single shot.
