Overview
The AZ23C43-7-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 43 V, with a specified range of 40 V to 46 V at a test current of 5.0 mA. Maximum power dissipation is rated at 300 mW, and the maximum Zener impedance (ZZT) is 100 Ohms at the test current. The device operates within a temperature range of -65°C to +150°C and exhibits a typical temperature coefficient of +0.110 %/°C.
Feature Summary
- Dual Zener diodes integrated in a common anode configuration for space-efficient circuit design.
- Qualified to JEDEC standards for high reliability applications.
- Compliant with RoHS directives and halogen-free manufacturing processes.
Applications
- Voltage reference circuits requiring dual independent references.
- Clamping and protection stages in signal processing paths.
- Biasing networks in analog electronic systems.
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm that the ordering suffix matches the required commercial grade specifications. Ensure packaging details align with automated assembly requirements before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener solution with a common anode topology is required. Verify that the 43 V nominal voltage and 300 mW power rating meet the specific circuit load conditions. Check compatibility with standard SOT-23 footprint layouts during the PCB design phase.
Part Context
This part belongs to the AZ23C series of dual surface mount Zener diodes. The series offers various voltage options ranging from 2.7 V to 51 V. The AZ23C43-7-F specifically provides the 43 V variant within this standardized product family.
Replacement Considerations
The DZ23C43-7-F serves as a functional alternative, offering identical electrical characteristics but utilizing a common cathode configuration instead of common anode.
