Overview
The AZ23C4V7-7-F 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 4.7 V, with a specified range of 4.4 V to 5.0 V at a test current (IZT) of 5.0 mA. Maximum Zener impedance is 78 Ohms at IZT and 500 Ohms at IZK = 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-Q100 standards for automotive applications requiring high reliability.
- Totally lead-free and fully RoHS compliant, ensuring compliance with environmental directives.
Applications
- Voltage regulation in automotive electronic systems

- Reference voltage generation in industrial control circuits
Procurement Notes
Verify the complete part number including suffixes against official distributor catalogs to ensure correct commercial qualification and packaging specifications. Confirm that the ordering information matches the required tape and reel quantity and carrier type before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener solution with a common anode topology is required in a compact SOT-23 footprint. Ensure the application voltage falls within the 4.4 V to 5.0 V range and consider the 300 mW power dissipation limit under expected operating ambient temperatures.
Part Context
This part belongs to the AZ23C series of dual surface mount Zener diodes from Diodes Incorporated. The series offers various voltage options ranging from 2.7 V to 51 V, all sharing the same mechanical package and general electrical characteristics while differing in specific breakdown voltages and impedances.
Replacement Considerations
The DZ23C4V7-7-F serves as a functional replacement if a common cathode configuration is acceptable instead of the common anode setup found in the AZ23C series. Verify pinout compatibility and impedance specifications before substitution.
