Overview
The AZ23C4V3-7-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 4.0 V to 4.6 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 -0.035 %/°C. Operating and storage temperatures range from -65 °C to +150 °C.
Feature Summary
- Dual Zeners in Common Anode Configuration
- Totally Lead-Free & Fully RoHS Compliant
- Halogen and Antimony Free "Green" Device
Applications
- Automotive applications requiring specific change control
- High reliability electronic circuits
- Voltage regulation and reference applications
Procurement Notes
Verify the exact ordering suffix against official documentation to confirm commercial versus automotive qualification status. Confirm that the requested part number matches the standard commercial tape and reel packaging format. Ensure compliance with relevant environmental directives such as RoHS 3 and halogen-free requirements before finalizing procurement orders.
Selection Notes
Select this component for designs requiring dual Zener diodes in a compact SOT-23 footprint. Consider the negative temperature coefficient when designing precision voltage references. Verify that the 300 mW power dissipation rating aligns with the thermal management capabilities of the target printed circuit board layout.
Part Context
This device belongs to the AZ23C series of dual surface mount Zener diodes produced by Diodes Incorporated. The series covers a wide range of nominal voltages from 2.7 V to 51 V within the same SOT-23 package form factor. This specific variant provides a 4.3 V nominal breakdown voltage suitable for low-voltage signal conditioning tasks.
Replacement Considerations
The DZ23C4V3-7 is available as a common cathode alternative within the same manufacturer's portfolio. Cross-referencing with other manufacturers requires verifying pinout compatibility and ensuring equivalent electrical parameters such as impedance and power ratings are met.
