Overview
The AZ23B11-E3-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23 series, housed in a SOT-23 surface-mount package. It provides two independent Zener diodes sharing a common anode terminal. The nominal Zener voltage is 11 V with a tight tolerance of ±2%. Electrical characteristics are defined at a test current of 5 mA, featuring a maximum reverse leakage current of 0.1 µA and a dynamic resistance of 20 Ω. The device operates within a temperature range of -55 °C to +150 °C and dissipates up to 300 mW on standard FR-4 boards.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- Tight ±2% voltage tolerance for precision regulation applications
- ESD protection capability exceeding 8 kV via human body model
Applications
- Precision voltage reference circuits requiring dual rails
- Overvoltage protection for sensitive signal lines
- Clamping applications in communication equipment
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status and check for AEC-Q101 automotive qualification requirements if applicable to the target application environment.
Selection Notes
Select this variant when a 2% tolerance is required instead of the standard 5% offered by the 'C' suffix. Ensure the 11 V breakdown voltage aligns with the specific circuit threshold needs and verify that the SOT-23 footprint matches the PCB layout constraints.
Part Context
This component belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay General Semiconductor. The series offers a wide range of standardized voltages from 2.2 V to 75 V across various packages including SOT-23 and SOD-323.
