Overview
The Taiwan Semiconductor AZ23C22 is a dual SMD Zener diode array housed in an SOT-23 package. It features a nominal Zener voltage of 22 V with a tolerance range of 20.8 V to 23.3 V. 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 test current of 5 mA, a maximum Zener impedance of 55 Ω at the test current, and a leakage current of 100 nA at 17 V reverse bias.
Feature Summary
- Dual common anode configuration for compact circuit design
- RoHS compliant and halogen-free construction
- Moisture sensitivity rated Level 1 per J-STD-020
- Ideally suited for automated assembly processes
Applications
- Low voltage stabilizers or voltage references
- Adapters
- Lighting applications
- On-board DC/DC converters
Procurement Notes
Verify the specific ordering suffix (e.g., RF, RFG) against the datasheet to confirm packaging details such as reel size and tape specifications. Ensure compliance requirements match project needs, noting that the 'G' suffix indicates green compound which is halogen-free according to IEC 61249-2-21 standards.
Selection Notes
Select this component when a dual Zener array in an SOT-23 package is required for space-constrained designs. Confirm that the 22 V nominal voltage falls within the acceptable tolerance band for the application. Verify thermal management capabilities, as the junction-to-ambient thermal resistance is approximately 420 °C/W under standard conditions.
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 series share the same SOT-23 mechanical footprint and general electrical testing conditions, allowing for consistent board layout across different voltage reference designs within the same product family.
Replacement Considerations
Cross-referencing requires matching the dual common anode configuration, SOT-23-3 package, and 22 V nominal voltage. Verify that substitute parts meet the 300 mW power dissipation rating and similar impedance and leakage current specifications to ensure functional equivalence.
