AZ23C30-7

Overview

The AZ23C30-7-F is a dual surface mount Zener diode array manufactured by Diodes Incorporated. It features two Zener diodes in a common anode configuration housed in an SOT-23 package. The nominal Zener voltage is 30 V with a tolerance range of 28 V to 32 V at a test current of 5.0 mA. Maximum power dissipation is rated at 300 mW, and the typical thermal resistance from junction to ambient air is 417 °C/W. The device operates within a temperature range of -65 °C to +150 °C. Electrical characteristics include a maximum Zener impedance (ZZT) of 80 Ω at 1 kHz and a typical temperature coefficient of +0.090 %/°C.

Feature Summary

• Dual Zener diodes integrated in a single common anode configuration for space-efficient circuit design.
• High reliability qualification compliant with JEDEC standards for demanding applications.
• Environmentally compliant construction that is fully lead-free, halogen-free, and antimony-free.
• Optimized physical dimensions and mounting style suitable for automated surface-mount insertion processes.

Applications

• Voltage reference circuits requiring stable dual supply rails.
• Over-voltage protection stages in signal conditioning paths.
• Clamping networks for transient suppression in electronic assemblies.

Procurement Notes

Verify the complete ordering suffix against official distributor catalogs to ensure correct commercial packaging and RoHS compliance status. Confirm that the specific batch matches the required automotive or industrial grade if functional safety is mandated. Cross-reference the manufacturer's latest datasheet revision to validate electrical parameters before finalizing procurement orders.

Selection Notes

Select this component when a matched pair of Zener diodes with a shared anode terminal is required in a compact footprint. Ensure the operating voltage aligns with the 28 V to 32 V breakdown range. Verify that the 300 mW power rating accommodates the expected thermal load without exceeding the maximum junction temperature limits defined in the thermal characteristics table.

Part Context

This part belongs to the AZ23C series of dual Zener arrays produced by Diodes Incorporated. The series spans various voltage ratings from 2.7 V to 51 V, all sharing the same SOT-23 mechanical outline and common anode topology. The AZ23C30 variant specifically targets applications needing a 30 V reference point within a low-profile surface-mount assembly.

Replacement Considerations

Direct substitutes include other manufacturers' dual common anode Zener arrays in SOT-23 packages with matching 30 V specifications. Verify pinout compatibility and thermal resistance values to ensure equivalent performance in existing layouts.

FAQ
