Overview
The AZ23C11-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 features a nominal Zener voltage of 11 V with a ±5% tolerance and a maximum power dissipation of 300 mW on an FR-4 board. The device operates within a temperature range of -55 °C to +150 °C and includes ESD protection exceeding 8 kV (HBM) and 800 V (MM). Electrical characteristics include a reverse leakage current of 0.1 µA at 8.5 V and a dynamic resistance of 20 Ω at a test current of 5 mA.
Feature Summary
- Dual common anode configuration for integrated circuit applications
- Green commercial grade construction compliant with RoHS standards
- ESD capability meeting AEC-Q101 human body model and machine model thresholds
Applications
- Voltage reference circuits requiring dual channels
- Clamping and protection stages in signal processing paths
- Biasing networks in low-power electronic modules
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer's part number against official datasheet documentation. Confirm that the ordering suffix matches the required reel quantity and tape specifications. Ensure compliance with environmental directives such as RoHS3 and material categorization requirements before finalizing procurement orders.
Selection Notes
Select this component when a dual common anode Zener array is required in a compact SOT-23 footprint. The ±5% tolerance suits general-purpose regulation tasks. Verify thermal management capabilities, as power dissipation drops significantly above ambient temperatures. Consider the specific test current requirements for dynamic resistance matching in precision designs.
Part Context
This part belongs to the AZ23-G series of small signal Zener diodes manufactured by Vishay General Semiconductor - Diodes Division. The series offers various voltage grades based on the E24 standard. The 'G3' suffix indicates green commercial grade packaging, while '18' specifies the 10,000 units per reel tape and reel format.
