AZ23C11-G3-08

Overview

The AZ23C11-G3-08 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 Zener elements sharing a common anode terminal. The nominal Zener voltage is 11 V with a standard tolerance of ±5%. Electrical testing is conducted at a test current (IZT1) of 5 mA. At this operating point, the maximum dynamic resistance (ZZ) is specified at 20 Ω, and the reverse leakage current (IR) does not exceed 0.1 μA when measured at 8.5 V. The device supports an operating temperature range from -55 °C to +150 °C.

Feature Summary

• Dual common anode configuration for space-efficient circuit design
• Zener voltages graded according to the international E24 standard
• ESD capability exceeding 8 kV via human body model and 800 V via machine model

Applications

• Voltage reference circuits requiring dual stable potentials
• Overvoltage protection for sensitive input lines
• Clamping applications in signal conditioning paths

Procurement Notes

Verify that the ordering code suffix matches the required reel quantity. The '-08' designation indicates units are supplied on an 8 mm tape wound on a 7-inch reel with a factory quantity of 3000 units. Confirm compliance requirements such as RoHS status and material categorization directly against the manufacturer's documentation before finalizing procurement orders.

Selection Notes

Select the 'C' suffix variant when a standard ±5% Zener voltage tolerance is acceptable for the application. If tighter precision is required, substitute the 'B' suffix part number which offers a ±2% tolerance. Ensure the selected component meets the specific thermal resistance and power dissipation limits dictated by the target PCB footprint and ambient operating conditions.

Part Context

This component belongs to the AZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series utilizes silicon planar technology and is available in various voltage grades ranging from 2.2 V to 75 V. All variants share the same SOT-23 physical footprint and electrical testing methodologies, allowing for standardized supply chain management across different voltage requirements.

Replacement Considerations

Direct functional equivalents within the same family include the AZ23B11-G3-08, which maintains identical pinout and packaging but provides a tighter ±2% voltage tolerance. Other series members like the AZ23C10 or AZ23C12 offer adjacent voltage ratings while retaining the dual common anode architecture and SOT-23 form factor.
