Overview
The AZ23C12-G3-18 is a dual common anode silicon planar Zener diode array from the AZ23-G series, manufactured by Vishay General Semiconductor. It provides two independent Zener diodes within a single SOT-23 surface-mount package. The nominal Zener voltage is 12 V with a tolerance of ±5 %. Electrical characteristics are defined at a test current (IZT1) of 5 mA, featuring a maximum reverse leakage current of 0.1 µA and a dynamic resistance (ZZ) of 20 Ω. The device supports a junction temperature up to 150 °C and operates within a temperature range of -55 °C to +150 °C.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- Silicon planar technology ensuring stable voltage regulation
- ESD protection capability exceeding 8 kV via human body model
Applications
- Voltage reference circuits requiring dual channels
- Overvoltage protection in signal lines
- Clamping applications in low-power electronics
Procurement Notes
Verify the specific ordering suffix '-18' to confirm the 10,000-unit reel packaging format. Ensure compatibility with standard SMT reflow soldering profiles and confirm that the commercial grade designation meets project requirements without additional automotive qualification.
Selection Notes
Select this component when a dual Zener array is required in a compact SOT-23 footprint. The ±5 % tolerance suits general-purpose applications where tighter precision is unnecessary. Verify that the 300 mW power dissipation rating on an FR-4 board aligns with the thermal constraints of the target PCB layout.
Part Context
This part belongs to the AZ23-G series of small signal Zener diodes. The 'C' designation indicates the standard ±5 % voltage tolerance, while the 'G3' suffix denotes compliance with RoHS directives and green manufacturing standards. The series covers a wide voltage range from 2.2 V to 75 V.

FAQ
What is the marking code for the AZ23C12-G3-18?
The marking code for this device is D57.
How does the package type affect power dissipation?
On an FR-4 board with the recommended soldering footprint, the total power dissipation is rated at 300 mW, whereas the absolute maximum rating is 500 mW based on thermal resistance to the lead.
Is this component AEC-Q101 qualified?
No, the standard AZ23C12-G3-18 is not AEC-Q101 qualified; automotive-grade versions are available upon request from the manufacturer.
