Overview
The AZ23C3V9-7-F is a dual surface mount Zener diode array 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 3.9 V, with a specified range of 3.7 V to 4.1 V at a test current (IZT) of 5.0 mA. Maximum power dissipation is rated at 300 mW, and the maximum Zener impedance (ZZT) is 95 Ω at IZT = 5.0 mA. The device 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.
- High reliability qualification compliant with JEDEC standards.
- Lead-free construction fully compliant with RoHS directives and free from halogens and antimony.
Applications
- Voltage reference circuits requiring dual independent references.
- Clamping applications for transient voltage suppression.
- Automotive electronics systems requiring high-reliability components.
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm that the ordering suffix matches commercial grade specifications. Ensure packaging details align with tape and reel requirements for automated assembly processes.
Selection Notes
Select this component when dual common anode Zener regulation is required in a compact SOT-23 footprint. Evaluate thermal resistance characteristics against ambient operating conditions. Verify impedance and leakage current parameters meet specific circuit tolerance requirements.
Part Context
This part belongs to the AZ23C series of dual Zener arrays produced by Diodes Incorporated. The series offers various voltage options ranging from 2.7 V to 51 V, all sharing the same physical package and electrical architecture. The -7-F suffix indicates commercial grade qualification and standard tape and reel packaging.
Replacement Considerations
The DZ23C3V9-7-F serves as a functional replacement offering a common cathode configuration instead of common anode. Designers must verify polarity alignment during substitution to ensure correct circuit operation.
