Overview
The AZ23C5V1-7-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 5.1 V with a tolerance range of 4.8 V to 5.4 V at a test current of 5.0 mA. Maximum power dissipation is rated at 300 mW, and the typical thermal resistance from junction to ambient air is 417 °C/W. 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 designs
- High reliability qualification compliant with JEDEC standards
- Lead-free and fully RoHS compliant construction
- Halogen and antimony free "Green" device classification
Applications
- Voltage reference circuits requiring dual stable potentials
- Clamping and protection stages in signal processing paths
- Biasing networks in analog electronic systems
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm commercial versus automotive grade status. Confirm that the requested part number matches the exact electrical characteristics required for the design. Ensure compliance with environmental directives such as RoHS 3 and REACH before finalizing procurement specifications.
Selection Notes
Select this component when a dual common anode Zener array is required in a compact SOT-23 footprint. Evaluate the maximum power dissipation limits relative to the expected operating ambient temperature. Consider the specific Zener impedance and leakage current parameters to ensure they meet the circuit's precision requirements.
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 ranging from 2.5 V to 51 V. The AZ23C5V1 variant specifically provides a 5.1 V breakdown voltage suitable for general-purpose voltage regulation tasks.
Replacement Considerations
The DZ23 series serves as the common cathode alternative within the same product family. Other manufacturers may offer equivalent dual Zener arrays in SOT-23 packages, but direct pin-compatible substitutes require verification of electrical parameters and package dimensions.
FAQ
What is the configuration of the internal diodes?
The device contains two Zener diodes connected in a common anode configuration.
Is this component qualified for automotive applications?
The standard AZ23C5V1-7-F is commercially qualified. Automotive-grade versions are available with a Q-suffix (e.g., AZ23C5V1Q-7-F) and are qualified to AEC-Q101 standards.
What is the maximum power dissipation rating?
The maximum power dissipation is 300 mW when mounted on an FR-4 PCB with the recommended pad layout.
