Overview
The AZ23C9V1HE3-TP is a dual Zener diode array manufactured by Micro Commercial Components (MCC). It features a common anode configuration housed in a surface-mount SOT-23 package. The nominal Zener voltage is 9.1 V with a tolerance of ±5%. The device supports a maximum power dissipation of 300 mW and operates within a junction temperature range of -55°C to +150°C. Key electrical parameters include a maximum reverse leakage current of 100 nA at 7 V and a Zener impedance of 10 Ohms.
Feature Summary
- Dual Zener diode array with common anode configuration for space-efficient circuit design
- Automotive-grade reliability certified under AEC-Q101 standards
- Halogen-free construction compliant with environmental regulations
Applications
- Voltage reference circuits requiring stable dual voltage levels
- Clamping and protection stages in automotive electronic modules
- Signal conditioning networks in industrial control systems
Procurement Notes
Verify the specific suffix HE3-TP against the official MCC datasheet to confirm halogen-free status and packaging type. Ensure the ordering part number matches the required tape-and-reel quantity. Cross-reference the manufacturer's latest product change notices to verify assembly origin and material compliance before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener solution with common anode topology is required in a compact SOT-23 footprint. The 9.1 V nominal voltage and 300 mW power rating suit low-power signal processing applications. Confirm that the 10 Ohm Zener impedance meets the dynamic performance requirements of the target circuit design.
Part Context
This component belongs to the AZ23 series of dual Zener arrays from Micro Commercial Components. The series offers various voltage options in the same SOT-23 package, facilitating standardized board layouts across different voltage reference designs. The HE3 designation indicates a lead-free and halogen-free variant within the product line.
Replacement Considerations
Publicly confirmed substitutes include AZ23C9V1-HE3_A-18 from Vishay General Semiconductor and MMBZ9V1ALT1G from onsemi. Verify pinout compatibility and thermal characteristics before substituting.
