Overview
The AZ23C12HE3-TP is a dual common anode Zener diode array manufactured by Micro Commercial Components. It features a nominal Zener voltage of 12 V with a 5% tolerance and a maximum power dissipation of 300 mW. The device operates within a junction temperature range of -55°C to +150°C and exhibits a maximum reverse leakage current of 100 nA at the specified test current of 5 mA. Packaged in a compact SOT-23 surface-mount housing, it maintains a Zener impedance of 20 Ohms and a voltage temperature coefficient of 0.075%/°C.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- Automotive-grade reliability certified under AEC-Q101 standards
- Compact SOT-23 surface-mount package for automated assembly
Applications
- Voltage reference circuits requiring stable dual rails
- Clamping and protection stages in automotive electronics
- Signal conditioning modules in industrial control systems
Procurement Notes
Verify component authenticity through authorized MCC distributors or verified platform listings. Confirm AEC-Q101 certification status and RoHS compliance documentation prior to procurement. Ensure storage conditions align with manufacturer specifications to maintain device integrity during handling and installation processes.
Selection Notes
Select this component when dual independent voltage regulation is required within a single footprint. The 12 V nominal rating suits applications needing precise mid-range reference levels. Verify that the 300 mW power budget accommodates peak operational currents without exceeding thermal limits in the target enclosure environment.
Part Context
This part belongs to the AZ23C series of dual Zener arrays from Micro Commercial Components. The series offers various voltage options in the same SOT-23 package, allowing designers to standardize on a single package type while adjusting voltage requirements across different product lines or revisions.
Replacement Considerations
Direct substitutes include other AZ23C12 variants from MCC such as AZ23C12-TP. Cross-manufacturer equivalents require matching Zener voltage, power dissipation, and package dimensions. Verify pinout compatibility and electrical tolerances before implementing any alternative sourcing strategy.
