Overview
The AZ23C8V2HE3-TP is a dual common anode Zener diode manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 8.2 V with a maximum reverse leakage current of 700 nA and a Zener impedance of 15 Ohms at a test current of 5 mA. The device operates within a temperature range of -55 C to +150 C, dissipating up to 300 mW of power. Packaged in an SOT-23-3 surface-mount format, it exhibits a voltage temperature coefficient of 6.2 mV/C.
Feature Summary
- Dual common anode configuration for efficient circuit design
- Surface-mount SOT-23-3 package for automated assembly
- Wide operating temperature range suitable for harsh environments
Applications
- Voltage reference circuits requiring dual polarity or differential sensing
- Clamping and protection stages in signal conditioning paths
- Biasing networks in analog integrated circuits
Procurement Notes
Verify the specific suffix HE3 indicates lead-free compliance and halogen-free status as per manufacturer documentation. Confirm the SOT-23-3 footprint matches the target PCB layout. Ensure the 300 mW power dissipation rating aligns with thermal management requirements in the final application environment.
Selection Notes
Select this component when a dual Zener structure is required in a compact SMD form factor. The 8.2 V nominal voltage and low leakage characteristics make it suitable for precision applications. Compare against single Zener alternatives if space allows, noting that the dual configuration reduces board area and interconnect complexity.
Part Context
This part belongs to the AZ23 series of dual Zener diodes from MCC. It shares the SOT-23-3 package with other variants like AZ23B20HE3-TP but differs in voltage rating and internal configuration. The series targets cost-sensitive consumer and industrial electronics requiring reliable voltage regulation.
Replacement Considerations
Direct substitutes include other dual common anode Zener diodes with similar 8.2 V ratings and SOT-23-3 packages. Verify pinout compatibility and electrical parameters such as leakage current and impedance before substitution.
