AZ23C3V3-7-F

Overview

The AZ23C3V3-7-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 3.1 V to 3.5 V at a test current of 5.0 mA. Maximum Zener impedance is specified as 95 Ω at IZT = 5.0 mA and 500 Ω at IZK = 1.0 mA. The typical temperature coefficient is -0.055 %/°C. 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 ESD protection ratings (HBM 8kV, MM 400V).
• 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 the stable low-voltage breakdown characteristic.
• ESD protection for signal lines where common anode topology is required.

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm commercial versus automotive qualification status. Ensure that the requested quantity aligns with standard tape and reel packaging requirements. Confirm compliance with RoHS and REACH directives based on the latest manufacturer declarations prior to final procurement authorization.

Selection Notes

Select this component when a dual Zener array with a common anode is required within a compact SOT-23 footprint. Evaluate the thermal resistance characteristics against the expected ambient temperature conditions to ensure the 300 mW power rating remains within safe operating limits. Verify that the negative temperature coefficient aligns with the circuit's stability requirements.

Part Context

This device belongs to the AZ23C series of dual surface mount Zener diodes produced by Diodes Incorporated. The series covers a wide voltage range from 2.7 V to 51 V, all sharing the same physical package dimensions and general electrical testing parameters. The product line is designed to provide standardized solutions for voltage regulation and clamping in consumer and industrial electronics.

Replacement Considerations

The DZ23 series serves as the common cathode alternative within the same manufacturer portfolio. Cross-referencing requires verifying pinout compatibility and ensuring the specific voltage tolerance matches the design constraints.
