AZ23C3V3-7

Overview

The AZ23C3V3-7 is a dual surface mount Zener diode 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 3.3 V, with a specified range of 3.1 V to 3.5 V at a test current (IZT) of 5.0 mA. Maximum Zener impedance is 95 Ω at IZT and 500 Ω at IZK of 1.0 mA. The device has a maximum power dissipation rating of 300 mW and operates within a 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 ESD protection ratings of 8kV HBM and 400V MM.
• Manufactured using lead-free, halogen-free, and antimony-free green materials compliant with RoHS directives.

Applications

• Automotive electronic systems requiring AEC-Q101 qualified components.
• ESD protection circuits utilizing the component's high electrostatic discharge tolerance.
• Voltage reference applications in surface mount assembly environments.

Procurement Notes

Verify the specific ordering suffix when sourcing this component. The base model number AZ23C3V3-7 lacks the commercial qualification suffix required for standard procurement. Confirm that the ordered part includes the -7-F suffix to ensure compliance with the commercial grade specifications detailed in the official datasheet.

Selection Notes

Select the AZ23C3V3-7-F variant to match the commercial grade specifications defined in the manufacturer documentation. Ensure the application requires a common anode configuration, as the alternative DZ23 series provides a common cathode arrangement. Verify that the 300mW power dissipation limit and SOT-23 package dimensions are suitable for the target PCB layout.

Part Context

This component belongs to the AZ23C2V7 through AZ23C51 family of dual surface mount Zener diodes produced by Diodes Incorporated. The family covers a wide voltage range from 2.7 V to 51 V, all sharing the same SOT-23 package and common anode topology. This specific part represents the 3.3 V nominal voltage option within that standardized lineup.

Replacement Considerations

Direct substitutes include other parts from the AZ23C series with matching voltage and configuration, or the DZ23 series if a common cathode configuration is acceptable. Automotive-grade equivalents require the Q-suffix designation, such as AZ23C3V3Q-7-F, which maintains the same electrical characteristics but meets stricter automotive quality standards.

FAQ

What is the difference between the AZ23C and DZ23 series?

The AZ23 series utilizes a common anode configuration for its dual Zener diodes, whereas the DZ23 series offers a common cathode configuration. Both series share similar electrical ratings and packaging options.

Is the AZ23C3V3-7 qualified for automotive applications?

The standard AZ23C3V3-7 is a commercial grade part. For automotive applications requiring AEC-Q101 qualification, the corresponding part with the Q-suffix, such as AZ23C3V3Q-7-F, must be selected.

What is the typical thermal resistance of this device?

The typical thermal resistance from junction to ambient air (RθJA) is 417 °C/W, measured when mounted on an FR-4 PC board with the recommended pad layout.
