Overview
The AZ23C4V3 is a dual common anode Zener diode array manufactured by Taiwan Semiconductor Corporation. It features a nominal Zener voltage of 4.3 V with a tolerance of ±5%. The device operates within a junction temperature range of -55°C to +150°C and has a maximum power dissipation of 300 mW. Electrical characteristics include a Zener impedance (Zzt) of 95 Ohms at a test current (Izt) of 5 mA, and a leakage current (Ir) of 0.1 µA at a reverse voltage (Vr) of 1 V. The component is housed in an SOT-23 package.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- Moisture sensitivity level 1 per J-STD-020 standards
- Halogen-free construction compliant with IEC 61249-2-21
- RoHS compliant with matte tin plated leads
Applications
- Low voltage stabilizers or voltage references
- Adapters
- Lighting applications
- On-board DC/DC converters
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details. The 'G' suffix indicates halogen-free green compound material. Confirm that the requested part number matches the exact voltage code and package type required for the intended application before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener configuration with a common anode is required in a compact surface-mount footprint. Ensure the operating voltage aligns with the 4.3 V nominal specification and verify that the 300 mW power dissipation rating meets the thermal requirements of the target circuit environment.
Part Context
This component belongs to the AZ23C series, which offers a wide selection of Zener voltages ranging from 2.7 V to 51 V. All devices in this series share the same SOT-23 package and mechanical specifications, differing primarily in their nominal Zener voltage ratings and corresponding electrical parameters.
Replacement Considerations
Direct substitutes within the same series include other dual common anode Zener arrays such as AZ23C3V0, AZ23C3V3, AZ23C3V6, AZ23C3V9, AZ23C4V7, and AZ23C5V1. Verify voltage compatibility and impedance values when considering these alternatives.
