Overview
The AZ23C2V7-G3-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23-G series, housed in a surface-mount SOT-23 package. It provides two independent Zener elements sharing a common anode terminal. The nominal Zener voltage is 2.7 V with a ±5% tolerance (indicated by the 'C' suffix). Electrical characteristics are measured at a test current of 5 mA, yielding a maximum dynamic resistance of 83 Ω and a reverse leakage current of 20 μA at 1.7 V. The device supports an operating temperature range from -55 °C to +150 °C and dissipates up to 300 mW on a standard FR-4 board.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- Zener voltages graded according to the international E24 standard
- ESD protection capability exceeding 8 kV via human body model
- Lead-free construction compliant with RoHS directives
Applications
- Voltage reference circuits requiring low-voltage stability
- Overvoltage protection for sensitive input lines
- Clamping applications in signal conditioning paths
Procurement Notes
Verify the specific ordering code against the manufacturer's official documentation to ensure correct voltage tolerance and packaging format. Confirm that the component meets the required environmental standards for the intended application environment before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener configuration with a common anode is required in a compact SOT-23 footprint. Ensure the design accounts for the 2.7 V nominal breakdown voltage and the associated dynamic resistance at the expected operating current to maintain desired regulation performance.
Part Context
This part belongs to the AZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of standardized voltage options within the same physical package, allowing designers to scale voltage requirements without changing the board layout or footprint constraints.
Replacement Considerations
Direct replacements include other AZ23C2V7 variants such as AZ23C2V7-E3-08 or AZ23C2V7-G3-18, which share identical electrical specifications but may differ in reel size or lead-free compliance details. Verify pinout compatibility and thermal characteristics before substitution.
FAQ
What does the 'C' designation indicate in the part number?
The 'C' indicates a standard Zener voltage tolerance of ±5%. A 'B' designation would indicate a tighter ±2% tolerance.
Is this component qualified for automotive applications?
Standard commercial versions are not automatically AEC-Q101 qualified. Automotive-qualified parts are available upon request directly from the manufacturer.
What is the maximum power dissipation on an FR-4 board?
The maximum power dissipation is 300 mW when mounted on an FR-4 board with the recommended soldering footprint.
