Overview
The AZ23C11-E3-18 is a dual common anode Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 11 V with a tolerance of ±5 %. The device operates within a test current range of 1 to 5 mA and exhibits a maximum reverse leakage current of 0.1 µA at 8.5 V. Dynamic resistance is specified at 20 Ω, while the temperature coefficient ranges from 5 to 9 x 10⁻⁴/°C. Packaged in a SOT-23 (TO-236-3) surface-mount housing, it supports an operating temperature range of -55 °C to +150 °C and complies with RoHS standards.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- Zener voltages graded according to international E24 standard
- ESD protection capability exceeding 8 kV via human body model
Applications
- Voltage reference circuits requiring dual regulated rails
- Clamping applications for signal lines
