Overview
The AZ23C16-G3-08 is a dual common-anode silicon planar Zener diode array from Vishay, housed in an SOT-23 surface-mount package. It provides two independent Zener elements sharing a single anode terminal. The nominal Zener voltage is 16 V with a standard tolerance of ±5%. Electrical characteristics are defined at a test current of 5 mA, featuring a maximum reverse leakage current of 0.05 µA and a dynamic resistance of 40 Ω. The device supports a junction temperature up to 150 °C and operates within a range of -55 °C to +150 °C.
Feature Summary
- Dual common-anode configuration for space-efficient circuit design
- Zener voltages graded according to the international E24 standard
- Green commercial grade material categorization compliant with RoHS directives
Applications
- Voltage reference circuits requiring dual stable potentials
- Overvoltage protection for sensitive electronic components
- Clamping applications in signal processing paths
Procurement Notes
Verify the specific suffix 'G3' confirms green commercial grade compliance and lead-free status. Confirm the '08' suffix indicates the 3000-unit reel packaging format. Ensure the ordering code matches the required ±5% tolerance designation ('C'). Validate that the component meets the intended environmental operating conditions.
Selection Notes
Select this part when a dual Zener solution with a shared anode is required in a compact SOT-23 footprint. The ±5% tolerance suits general-purpose regulation tasks. Verify that the 300 mW power dissipation on FR-4 boards aligns with the thermal management capabilities of the target PCB layout and ambient temperature constraints.
Part Context
This component belongs to the AZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of Zener voltages from 2.2 V to 75 V across various tolerance grades. The AZ23C16 variant specifically targets the 16 V segment of the E24 standard voltage ladder.

FAQ
What is the marking code for the AZ23C16-G3-08?
The marking code for this device is D60.
How does the tolerance change if the 'C' is replaced with 'B' in the ordering code?
Replacing 'C' with 'B' changes the standard Zener voltage tolerance from ±5% to ±2%.
Is the AZ23C16-G3-08 AEC-Q101 qualified?
No, the standard AZ23C16-G3-08 is not AEC-Q101 qualified; automotive qualification requires a specific part number requested directly from the manufacturer.
