Overview
The AZ23B3V0-G3-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23-G series, housed in a SOT-23 surface-mount package. It features a nominal Zener voltage of 3.0 V with a tight ±2% tolerance, indicated by the 'B' designation in the part number. The device operates at a test current of 5 mA and provides a maximum reverse leakage current of 1 µA at 1 V. Electrical characteristics include a dynamic resistance (ZZ) of 95 Ω and a temperature coefficient ranging from -9 to -3 x 10⁻⁴/°C. It supports an operating temperature range from -55 °C to +150 °C.
Feature Summary
- Dual common anode configuration for space-efficient circuit designs
- Tight ±2% Zener voltage tolerance for precision regulation applications
- ESD protection capability exceeding 8 kV via human body model
Applications
- Precision voltage reference circuits requiring low tolerance
- Over-voltage protection stages in sensitive electronics
- Clamping applications in signal conditioning paths
Procurement Notes
Verify the specific ordering code suffix against official manufacturer documentation to confirm tape-and-reel specifications and compliance status. Confirm that the component meets all required environmental standards for the intended deployment environment before finalizing procurement orders.
Selection Notes
Select this variant when a strict ±2% voltage tolerance is mandatory, as opposed to the standard ±5% available in the 'C' graded series. Ensure the application can accommodate the specified dynamic resistance and leakage current limits at the target operating temperature range.
Part Context
This component belongs to the AZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series utilizes silicon planar technology and is designed for general-purpose voltage regulation tasks in compact surface-mount layouts.
Replacement Considerations
Direct replacements within the same family include AZ23C3V0-G3-08, which offers identical electrical functionality but with a wider ±5% voltage tolerance specification.
FAQ
What does the 'B' character signify in the AZ23B3V0-G3-08 part number?
The 'B' indicates that the Zener voltage tolerance is graded at ±2%, providing tighter accuracy compared to the standard ±5% tolerance found in the 'C' graded variants.
Is the AZ23B3V0-G3-08 qualified for automotive applications?
No, the standard AZ23B3V0-G3-08 is not AEC-Q101 qualified. Automotive-grade versions are available upon request directly from the manufacturer.
What is the maximum power dissipation on an FR-4 board?
When mounted on an FR-4 board using the recommended soldering footprint, the maximum power dissipation is rated at 300 mW.
