AZ23C10-7-F

Overview

The AZ23C10-7-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 9.4 V to 10.6 V at a test current of 5.0 mA. Maximum Zener impedance is specified as 15 Ω at IZT = 5.0 mA and 70 Ω at IZK = 1.0 mA. The typical temperature coefficient is +0.065 %/°C, and the maximum reverse leakage current is 0.1 µA at 7.5 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 circuit design.
• Qualified to AEC-Q101 standards with high ESD protection ratings (HBM 8kV, MM 400V) suitable for automotive environments.
• Manufactured using lead-free, halogen-free, and antimony-free green molding compounds compliant with RoHS directives.

Applications

• Automotive electronic systems requiring AEC-Q101 qualified components
• Voltage reference circuits utilizing dual common anode topology
• Overvoltage protection stages in surface mount assembly lines

Procurement Notes

Verify the complete part number including the suffix against official Diodes Incorporated documentation before ordering. Confirm that the commercial grade qualification meets project requirements, noting that automotive applications typically require the Q-suffix variant. Ensure procurement channels are authorized to maintain component integrity and traceability.

Selection Notes

Select this component when a dual Zener array with a common anode 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 9.4 V to 10.6 V breakdown range aligns with the specific voltage regulation needs of the target application.

Part Context

This device belongs to the AZ23C2V7 through AZ23C51 series of dual surface mount Zener diodes. The family offers various voltage options while maintaining consistent mechanical dimensions and electrical characteristics across the range. The standard commercial version utilizes the -7-F suffix, distinguishing it from the automotive-grade variants which carry a Q-suffix.

Replacement Considerations

Direct replacements include other AZ23C10 variants such as AZ23C10-7 or AZ23C10Q-7-F. Cross-manufacturer equivalents must be verified for pin compatibility, impedance values, and package dimensions to ensure functional parity without board modifications.
