Overview
The Taiwan Semiconductor AZ23C24 is a dual common anode Zener diode housed in an SOT-23 package. It features a nominal Zener voltage of 24 V with a tolerance range of 22.8 V to 25.6 V at a test current (Izt) of 1 mA. The device has a maximum power dissipation of 300 mW and a junction temperature range from -55 °C to +150 °C. Electrical characteristics include a maximum Zener impedance (Zzt) of 80 Ω and a leakage current (Ir) of 1 µA at 18 V. The marking code for this component is KDO.
Feature Summary
- Dual common anode configuration suitable for automated assembly processes
- Moisture sensitivity rated at Level 1 per J-STD-020
- Halogen-free construction compliant with IEC 61249-2-21
Applications
- Low voltage stabilizers or voltage references
- Adapters
- Lighting applications
- On-board DC/DC converters
Procurement Notes
Verify the specific ordering suffix, such as RFG or RF, against the manufacturer's datasheet to confirm packaging details like reel size and tape specifications. Ensure compliance requirements match project needs, specifically checking for halogen-free status and RoHS certification before finalizing procurement orders.
Selection Notes
Select the AZ23C24 when a dual common anode topology is required within a compact SOT-23 footprint. Confirm that the 300 mW power dissipation rating and the 24 V nominal breakdown voltage align with the circuit design constraints. Verify thermal resistance parameters if operating near maximum junction temperatures.
Part Context
This component 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 the same SOT-23 mechanical outline and general electrical testing conditions, differing primarily in their specific voltage ratings and corresponding marking codes.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires independent verification of pinout compatibility, voltage tolerances, and package dimensions.
