Overview
The AZ23C4V7HE3-TP is a dual common anode Zener diode array manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 4.7 V with a maximum reverse leakage current of 3 uA and a Zener impedance of 80 Ohms at a test current of 5 mA. The device dissipates up to 300 mW and operates within a temperature range of -55 C to +150 C. Packaged in an SOT-23-3 surface-mount case, it exhibits a voltage temperature coefficient of 0.2 mV/C.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- Automotive-grade reliability with AEC-Q101 qualification
- Low leakage current characteristics for precision applications
Applications
- Instrument cluster solutions for real-time vehicle data processing
- Digitally enhanced dashboard voltage regulation
- General-purpose Zener reference circuits in automotive electronics
Procurement Notes
Verify the specific ordering suffix against official MCC documentation to confirm package type and tape-and-reel specifications. Confirm AEC-Q101 automotive qualification status directly from the manufacturer datasheet before integration into safety-critical systems. Ensure the SOT-23-3 footprint matches the target PCB layout requirements.
Selection Notes
Select this component when a dual Zener structure with common anode topology is required in a compact SMD package. The 4.7 V breakdown voltage suits low-voltage reference applications. Verify that the 300 mW power dissipation rating meets the thermal constraints of the intended operating environment.
Part Context
This part belongs to the AZ23B4V7 series of dual Zener arrays from Micro Commercial Components. It shares the SOT-23-3 form factor with other variants in the family but differs in specific electrical parameters such as leakage and impedance. The HE3 designation typically indicates a specific manufacturing process or material composition defined by MCC.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Cross-reference with other manufacturers' dual common anode Zener arrays only after verifying exact electrical parameter alignment.
