Overview
The AZ23C4V3HE3-TP is a dual common anode Zener diode array manufactured by Micro Commercial Components. It features a nominal Zener voltage of 4.3 V with a maximum reverse leakage current of 100 nA and a Zener impedance of 95 Ohms at a test current of 5 mA. The device operates within a temperature range of -65°C to +150°C and has a power dissipation rating of 300 mW. Packaged in an SOT-23-3 surface-mount case, it measures 2.9 mm in length, 2.4 mm in width, and 1 mm in height.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- Automotive-grade reliability certified under AEC-Q101 standards
- Low leakage current characteristics for precision applications
Applications
- Voltage reference circuits requiring stable low-voltage regulation
- Clamping and protection stages in automotive electronic modules
- Signal conditioning networks in industrial control systems
Procurement Notes
Verify the specific suffix HE3-TP against official Micro Commercial Components documentation to confirm compliance with halogen-free requirements and RoHS directives. Ensure that the ordering information matches the exact electrical specifications required for the target application before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener structure with common anode topology is required in a compact SOT-23-3 package. Consider the 4.3 V nominal voltage and 300 mW power dissipation limits relative to the expected operating conditions and thermal environment of the host system.
Part Context
This part belongs to the AZ23C series of dual Zener arrays from Micro Commercial Components. It shares the SOT-23-3 footprint with other variants in the family but differs in Zener voltage ratings and specific electrical parameters tailored for different voltage regulation needs.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with alternative manufacturers only through direct comparison of datasheet electrical parameters and pin configurations.
