AZ23C11

Overview

The Taiwan Semiconductor AZ23C11 is a dual common anode Zener diode array housed in an SOT-23 package. It provides a nominal Zener voltage of 11 V with a tolerance of ±5%, ranging from 10.4 V to 11.6 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 maximum Zener impedance of 20 Ω at a test current of 5 mA, and a leakage current not exceeding 1 µA at 8.5 V reverse voltage.
