Overview
The Taiwan Semiconductor AZ23C20 is a dual common anode Zener diode housed in an SOT-23 package. It provides a nominal Zener voltage of 20 V with a tolerance range of 18.8 V to 21.2 V at a test current of 5 mA. The device supports a maximum power dissipation of 300 mW and operates within a junction temperature range of -55°C to +150°C. Electrical characteristics include a maximum Zener impedance of 50 Ohms at the test current and a leakage current not exceeding 0.1 µA at a reverse voltage of 15.0 V.
Feature Summary
- Dual common anode configuration for efficient space utilization
- Designed for automated assembly processes
- Moisture sensitivity level 1 per J-STD-020
Applications
- Low voltage stabilizers or voltage references
- Adapters
- Lighting applications
- On-board DC/DC converters
Procurement Notes
Verify the specific ordering suffix against the manufacturer's documentation, as variations exist for reel packaging and halogen-free compliance. Confirm that the component meets RoHS standards and IEC 61249-2-21 requirements for your project specifications. Ensure the selected variant matches the required tape and reel dimensions for your pick-and-place equipment.
Selection Notes
Select this component when a dual Zener solution is required in a compact SOT-23 footprint. The dual common anode structure allows for independent regulation of two lines using a single ground reference. Verify that the 300 mW power rating and 20 V breakdown voltage align with the circuit's thermal and electrical constraints.
Part Context
This part belongs to the AZ23C series, which covers a wide Zener voltage selection from 2.7 V to 51 V. All devices in this family share identical mechanical data, including the SOT-23 case and matte tin-plated leads. The series is designed to meet JESD 201 class 1A whisker test requirements.
Replacement Considerations
Cross-reference with other manufacturers offering dual common anode Zener diodes in SOT-23 packages. Ensure equivalent parameters such as 300 mW power dissipation, 20 V nominal voltage, and similar impedance values are met before substitution.
