Overview
The AZ23B11-G3-18 is a dual common anode silicon planar Zener diode array from the Vishay AZ23-G series, housed in a SOT-23 surface-mount package. It provides two independent voltage regulation channels sharing a single 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 supports a power dissipation of 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
- High ESD protection capability exceeding 8 kV (HBM) and 800 V (MM)
- Green commercial grade construction compliant with RoHS standards
Applications
- Precision voltage reference circuits requiring dual rails
- Over-voltage protection stages in signal conditioning paths
- Clamping networks for sensitive input/output interfaces
- Voltage threshold detection logic in embedded systems
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm reel size and tape specifications. Confirm that the component meets required environmental compliance standards for the target application. Ensure proper handling procedures are followed during assembly to maintain the integrity of the small outline transistor package.
Selection Notes
Select this variant when a dual-channel solution with high accuracy is required in a compact footprint. The ±2% tolerance distinguishes it from the standard ±5% 'C' series variants. Consider the thermal resistance and power dissipation limits when designing for high ambient temperatures or continuous operation conditions.
Part Context
This component belongs to the AZ23-G series of small signal Zener diodes manufactured by Vishay General Semiconductor. The series offers a wide range of graded Zener voltages from 2.2 V to 75 V. The 'B' designation indicates the tighter voltage tolerance option, while the '-G3' suffix denotes green, lead-free packaging compliant with international environmental directives.
