AZ23C12-7-F

Overview

The AZ23C12-7-F is a dual surface mount Zener diode manufactured by Diodes Incorporated, housed in an SOT-23 package. It features a common anode configuration with a maximum power dissipation of 300 mW. The nominal Zener voltage ranges from 11.4 V to 12.7 V at a test current of 5.0 mA. Maximum Zener impedance is specified as 20 Ω at IZT = 5.0 mA and 90 Ω at IZK = 1.0 mA. The typical temperature coefficient is +0.075 %/°C, and the maximum reverse leakage current is 0.1 µA at VR = 9.0 V. Operating and storage temperatures range from -65 °C to +150 °C.

Feature Summary

• Dual Zener diodes integrated in a single common anode configuration for space-efficient designs.
• Qualified to AEC-Q101 standards with high electrostatic discharge protection ratings.
• Manufactured using lead-free, halogen-free, and antimony-free green molding compounds.

Applications

• Automotive electronic circuits requiring AEC-Q101 qualified components.
• Voltage reference applications utilizing dual independent channels.
• Clamping and protection circuits in compact surface-mount layouts.

Procurement Notes

Verify the complete part number including the suffix against official manufacturer documentation before ordering. Confirm that the commercial grade qualification meets project requirements, noting that automotive-grade variants utilize a distinct Q-suffix. Ensure procurement channels are authorized to guarantee component authenticity and traceability.

Selection Notes

Select this component when a dual Zener array with a common anode topology is required within a compact SOT-23 footprint. Evaluate the 300 mW power dissipation limit against thermal derating curves for ambient temperatures exceeding 25 °C. Verify that the specific Zener voltage tolerance and impedance characteristics align with circuit precision requirements.

Part Context

This device belongs to the AZ23C series of dual surface mount Zener diodes produced by Diodes Incorporated. The series spans various voltage ratings from 2.7 V to 51 V, all sharing identical mechanical dimensions and packaging formats. The product line is designed to provide flexible voltage regulation options while maintaining compatibility with automated insertion processes.

Replacement Considerations

The DZ23 series serves as a functional alternative if a common cathode configuration is preferred over the standard common anode design. Direct pin-compatible replacements must be verified against electrical parameters such as impedance and leakage current to ensure circuit performance remains unaffected.

FAQ

What is the ESD sensitivity rating for the AZ23C12-7-F?

The component is qualified to AEC-Q101 with an HBM rating of 8kV and an MM rating of 400V. It also meets IEC 61000-4-2 standards with 15kV air discharge and 8kV contact discharge protection.

How does the power dissipation change with temperature?

The device has a maximum power dissipation of 300 mW at 25 °C. Thermal derating is required for operation above this temperature, following the curve provided in the datasheet to prevent junction overheating.

Is there an automotive-grade version of this component?

Yes, automotive applications requiring specific change control and IATF 16949 manufacturing should use the corresponding part with the Q-suffix (e.g., AZ23C12Q-7-F), which is qualified to AEC-Q101/100/104/200 standards.
