Overview
The Taiwan Semiconductor AZ23C12 is a dual common anode Zener diode housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 12 V with a tolerance range of 11.4 V to 12.7 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 20 Ω, a leakage current of 1 µA at 9.0 V, and compliance with RoHS standards.
Feature Summary
- Dual common anode configuration for efficient circuit design
- Moisture sensitivity level 1 per J-STD-020
- Halogen-free construction according to IEC 61249-2-21
- Meets JESD 201 class 1A whisker test requirements
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 official documentation to confirm packaging details such as reel size and tape specifications. Confirm RoHS compliance status and halogen-free certification directly from the datasheet before procurement. Ensure the component meets the required moisture sensitivity level for the intended assembly process.
Selection Notes
Select this component when a dual Zener solution with a common anode is required in a compact SOT-23 footprint. Verify that the 12 V nominal voltage and 300 mW power rating align with the circuit's thermal and electrical constraints. Consider the 5% voltage tolerance and operating temperature range for environmental suitability.
Part Context
The AZ23C12 belongs to the AZ23C series, which covers Zener voltages from 2.7 V to 51 V. This series is designed for automated assembly processes and utilizes a planar die construction. The part is manufactured by Taiwan Semiconductor Corporation and is available in standard surface-mount packaging formats.
Replacement Considerations
Cross-reference with other manufacturers offering dual common anode Zener diodes in SOT-23 packages. Verify equivalent parameters including Zener voltage, impedance, and power dissipation. Check for AEC-Q101 qualification if automotive reliability is required, as some competitors offer qualified variants.
