AZ23C16

Overview

The Taiwan Semiconductor AZ23C16 is a dual common anode Zener diode array housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 16 V with a tolerance range of 15.3 V to 17.1 V at a test current of 5 mA. The device features a maximum power dissipation of 300 mW and a Zener impedance of 40 Ohms at the specified test current. Maximum reverse leakage current is limited to 100 µA at 12.0 V. The component operates within a junction temperature range of -55°C to +150°C and includes a thermal resistance from junction to ambient of 420°C/W.

• Lighting applications
• On-board DC/DC converters

Procurement Notes

Verify the specific ordering suffix (e.g., RFG) against the manufacturer's official documentation to ensure correct packaging and halogen-free status. Confirm RoHS compliance details directly with the supplier, as specifications are subject to change without notice. Ensure the selected variant matches the required tape and reel dimensions for automated assembly processes.

Selection Notes

Select this component when a dual Zener array with a 16 V nominal breakdown is required in a compact SOT-23 footprint. Verify that the 300 mW power dissipation rating accommodates the expected operating conditions. Check the 40 Ohm Zener impedance specification against signal integrity requirements. Ensure the design accounts for the 100 µA maximum reverse leakage current at the specified test voltage.

Part Context

The AZ23C16 belongs to the AZ23C series, which covers Zener voltages from 2.7 V to 51 V. All devices in this family share the same SOT-23 mechanical outline and 300 mW power dissipation capability. The series is designed for automated assembly and offers consistent electrical characteristics across the voltage range, facilitating standardized inventory management for various reference voltage needs.

Replacement Considerations

Cross-reference with other manufacturers' dual common anode Zener arrays in SOT-23 packages. Verify matching electrical parameters, specifically the 16 V nominal voltage, 300 mW power rating, and 40 Ohm impedance. Ensure physical pinout compatibility and thermal performance metrics align with the original design constraints.
