AZ23C22-7-F

Overview

The AZ23C22-7-F is a dual surface mount Zener diode array manufactured by Diodes Incorporated. It features two Zener diodes in a common anode configuration within a single SOT-23 package. The nominal Zener voltage is 22 V with a tolerance range of 20.8 V to 23.3 V at a test current of 5.0 mA. Maximum power dissipation is rated at 300 mW, and the typical temperature coefficient is +0.090 %/°C. The device operates within a junction temperature range of -65°C to +150°C.

Feature Summary

• Dual Zener diodes integrated in a common anode configuration for space-efficient circuit design.
• Qualified to AEC-Q101 standards with high electrostatic discharge (ESD) protection ratings.
• Manufactured using lead-free, halogen-free, and antimony-free materials compliant with RoHS directives.

Applications

• Automotive electronic systems requiring AEC-Q101 qualified components.
• Voltage reference applications utilizing dual independent regulation channels.
• Transient voltage suppression circuits in compact surface-mount layouts.

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm commercial versus automotive qualification status. Ensure that the requested part number matches the exact electrical characteristics required for the target application environment. Cross-reference datasheet revision numbers to guarantee compatibility with current manufacturing specifications.

Selection Notes

Select this component when a dual-channel voltage regulation solution is required in a minimal footprint. The common anode topology allows for shared biasing connections, simplifying PCB routing. Evaluate thermal derating requirements based on ambient operating conditions to ensure the 300 mW power rating remains within safe limits during continuous operation.

Part Context

This component belongs to the AZ23C series, which encompasses various Zener voltage options ranging from 2.7 V to 51 V. All variants share identical physical packaging and pinout configurations while differing in specific electrical parameters such as breakdown voltage and impedance. The series provides a standardized platform for integrating multiple voltage references into a single package.

Replacement Considerations

The DZ23C22-7 is a compatible alternative offering a common cathode configuration instead of common anode. Verify polarity requirements before substitution. Other AZ23C series parts with different voltage ratings may serve as functional replacements if the electrical specifications align with the circuit design needs.
