Overview
The AZ23B12-HE3-08 is a dual common anode Zener diode array from the Vishay AZ23 series, housed in a surface-mount SOT-23 package. It features a nominal Zener voltage of 12 V with a tight tolerance of ±2%. The device operates at a test current of 5 mA and has a maximum reverse leakage current of 0.1 µA at 9 V. Electrical characteristics include a dynamic resistance of 20 Ω and a temperature coefficient ranging from 6 to 9 x 10⁻⁴/°C. It is qualified under AEC-Q101 standards for automotive applications.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- AEC-Q101 qualification ensuring reliability in automotive environments
- High ESD protection capability exceeding 8 kV via human body model
Applications
- Automotive electronic circuits requiring robust voltage regulation
- General-purpose voltage reference applications
- Clamping and protection circuits in sensitive electronics
Procurement Notes
Verify component authenticity by checking the manufacturer's marking code against official documentation. Confirm that the HE3_A suffix indicates AEC-Q101 qualification and RoHS compliance. Ensure the ordering code matches the specific voltage and tolerance requirements for the intended application before finalizing procurement.
Selection Notes
Select this component when a precise 12 V reference with ±2% tolerance is required in a compact SOT-23 footprint. The dual common anode structure allows for independent control of two Zener paths. Consider the low leakage current and high ESD rating for use in noisy or safety-critical automotive systems where standard commercial grade parts may be insufficient.
Part Context
This part belongs to the Vishay AZ23 series of small signal Zener diodes. The series offers various voltage grades based on the E24 standard. The 'B' designation indicates a tighter ±2% tolerance compared to the standard ±5% 'C' grade. The 'HE3' suffix denotes a specific lead-free termination system compliant with environmental directives.
