AZ23C4V7-7-G

Overview

The AZ23C4V7-7-G is a dual common anode Zener diode array manufactured by Diodes Incorporated. It features two independent Zener diodes sharing a common anode terminal within a compact SOT-23 surface-mount package. The device provides a nominal Zener voltage of 4.7 V with a 5% tolerance, tested at a current of 5 mA. It supports a maximum power dissipation of 300 mW and operates across a temperature range from -65°C to +150°C. Key electrical characteristics include a maximum reverse leakage current of 100 nA and a Zener impedance of 78 Ohms. This component is designed for precision voltage regulation applications requiring small form factors.
