Overview
The AZ23C20HE3-TP is a dual common anode Zener diode manufactured by Micro Commercial Components. It features a nominal Zener voltage of 20 V at a test current of 5 mA, with a maximum reverse leakage current of 100 nA and a Zener impedance of 55 Ohms. The device operates within a temperature range of -55 C to +150 C and dissipates up to 300 mW. Packaged in an SOT-23-3 surface-mount format, it exhibits a voltage temperature coefficient of 18 mV/C.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- Surface-mount SOT-23-3 package suitable for automated assembly
- Wide operating temperature range supporting harsh environments
Applications
- Voltage reference circuits requiring dual polarity regulation
- Clamping applications in signal processing paths
- Over-voltage protection stages in compact electronic devices
Procurement Notes
Verify the specific manufacturer datasheet for detailed electrical characteristics and mechanical dimensions before integration. Confirm that the SOT-23-3 footprint matches the target PCB layout. Ensure thermal management strategies align with the 300 mW power dissipation rating under expected operating conditions.
Selection Notes
Select this component when a dual Zener structure is required in a minimal footprint. The 20 V breakdown voltage suits mid-range reference applications. Consider the 55 Ohm impedance for dynamic load requirements. Verify compatibility with standard reflow soldering profiles for SMD components.
Part Context
This part belongs to the AZ23C series of dual Zener diodes from Micro Commercial Components. It shares the SOT-23-3 packaging with other variants in the family but differs in breakdown voltage and internal configuration. The HE3 suffix typically indicates lead-free and halogen-free compliance standards.
Replacement Considerations
Direct substitutes include other dual common anode Zener diodes in SOT-23 packages with similar 20 V ratings. Verify pinout compatibility and thermal resistance values. Cross-reference impedance and leakage specifications to ensure circuit performance remains within acceptable limits.
