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 two independent Zener elements within a single case. 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 device supports a maximum power dissipation 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.
- High reliability qualification compliant with JEDEC standards for demanding applications.
- Environmentally friendly construction that is fully RoHS compliant, lead-free, halogen-free, and antimony-free.
Applications
- Voltage reference circuits requiring stable dual voltage rails.
- Clamping and protection stages in signal processing paths.
- Automotive electronic systems utilizing AEC-Q101 qualified components.
Procurement Notes
Verify the specific ordering suffix against official Diodes Incorporated documentation to confirm commercial versus automotive grade status. Ensure the requested quantity aligns with standard tape and reel packaging requirements. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability 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. Evaluate the 300 mW power dissipation limit against thermal constraints in the target application. Confirm that the 4.0 V to 4.6 V voltage range meets the specific clamping or reference requirements of the circuit design.
Part Context
This component belongs to the AZ23C series of dual surface mount Zener diodes produced by Diodes Incorporated. The series offers various voltage options within the same SOT-23 package form factor. The product line is designed to provide cost-effective solutions for voltage regulation and protection tasks in consumer and industrial electronics.
Replacement Considerations
Direct replacements include other AZ23C4V3 variants from Diodes Incorporated. Alternative manufacturers offering dual Zener diodes in SOT-23 packages with similar electrical characteristics may be considered if pin compatibility and voltage tolerances are verified.
FAQ
What is the typical temperature coefficient for the AZ23C4V3?
The typical temperature coefficient is -0.035 %/°C.
Is the AZ23C4V3-7-F suitable for automotive applications?
The standard -7-F suffix denotes commercial qualification. Automotive-grade versions are available with the Q-suffix (e.g., AZ23C4V3Q-7-F) which are qualified to AEC-Q101 standards.
What is the maximum reverse leakage current specified?
The datasheet specifies a maximum reverse leakage current (IR) of 0.1 µA at the specified reverse voltage conditions.
