Overview
The AZ23C27-E3-18 is a dual common-anode Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It provides two independent Zener diodes within a single SOT-23 package, designed for voltage regulation and protection applications. The nominal Zener voltage is 27 V with a tolerance of ±5%. Electrical characteristics include a maximum reverse leakage current of 0.05 µA at 20 V and a dynamic resistance of 80 Ω at the test current of 2 mA. The device operates within a temperature range of -55°C to +150°C and is supplied in tape-and-reel packaging containing 10,000 units per reel.
Feature Summary
- Dual common-anode configuration integrates two Zener diodes into a compact footprint.
- Silicon planar construction ensures stable performance across wide temperature ranges.
- ESD capability exceeds 8 kV via human body model and 800 V via machine model.
Applications
- Voltage reference circuits requiring dual regulated rails
- Overvoltage protection for signal lines
- Clamping applications in consumer electronics
