Overview
The AZ23B20HE3-TP is a dual common anode Zener diode array manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 20 V at a test current of 5 mA. The device operates within a temperature range of -55°C to +150°C and dissipates up to 300 mW. Key electrical parameters include a maximum reverse leakage current of 100 nA, a Zener impedance of 55 Ohms, and a voltage temperature coefficient of 18 mV/°C. It is housed in an SOT-23-3 surface-mount package.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- Surface-mount SOT-23-3 packaging for automated assembly
- Wide operating temperature range suitable for harsh environments
Applications
- Voltage reference circuits requiring dual stable potentials
- Over-voltage protection stages in signal conditioning paths
- Clamping applications in low-power electronic systems
Procurement Notes
Verify the specific datasheet version against the manufacturer's official documentation before integration. Confirm that the SOT-23-3 footprint matches the target PCB layout. Ensure thermal management strategies account for the 300 mW power dissipation limit under worst-case operating conditions.
Selection Notes
Select this component when a dual Zener solution with a common anode is required in a compact form factor. The 20 V breakdown voltage and 55 Ohm impedance define its suitability for specific clamping thresholds. Evaluate the 18 mV/°C temperature coefficient against the system's stability requirements across the specified -55°C to +150°C range.
Part Context
This part belongs to the AZ23B series of dual Zener arrays from Micro Commercial Components. The series utilizes standard SOT-23-3 packaging to provide two independent Zener junctions sharing a single anode terminal. This configuration reduces board space compared to discrete components while maintaining consistent electrical characteristics.
Replacement Considerations
Cross-reference with other AZ23B series variants for different voltage ratings. Verify pinout compatibility with the existing SOT-23-3 footprint. Ensure replacement parts maintain equivalent power dissipation and temperature rating specifications.
