AZ23C3V3-G3-08

Overview

The AZ23C3V3-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 features a nominal Zener voltage of 3.3 V with a ±5% tolerance and a test current of 5 mA. The device has a maximum power dissipation of 300 mW on an FR-4 board and operates within a temperature range of -55 °C to +150 °C. Electrical characteristics include a reverse leakage current of 5 μA at 2.97 V and a dynamic resistance of 95 Ω at 5 mA.

Feature Summary

• Dual common anode configuration for space-efficient circuit design
• Graded Zener voltages according to international E24 standard
• ESD protection capability exceeding 8 kV (HBM) and 800 V (MM)
• Lead-free construction compliant with RoHS directives

Applications

• Voltage reference circuits requiring dual stable potentials
• Clamping and protection stages in signal processing paths
• Biasing networks in low-power analog applications

Procurement Notes

Verify component authenticity by cross-referencing the ordering code against official Vishay documentation. Confirm that the specific suffix matches the required tape-and-reel packaging format and tolerance grade. Ensure compliance with environmental standards relevant to the target deployment region before finalizing procurement orders.

Selection Notes

Select this variant when a dual common anode topology is required alongside a precise 3.3 V reference point. The ±5% tolerance suits general-purpose regulation tasks where tighter precision is unnecessary. Evaluate thermal constraints carefully, as the 300 mW rating depends on adequate PCB copper area for heat dissipation during continuous operation.

Part Context

This component belongs to the AZ23-G series of small-signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of standardized voltage values in compact SOT-23 packages, designed for high-volume surface-mount assembly processes in consumer and industrial electronics.

Replacement Considerations

Direct functional equivalents within the same series include AZ23B3V3-G3-08 for tighter tolerance requirements or AZ23C3V3-G3-18 for alternative reel packaging. Verify pinout compatibility and thermal characteristics when substituting with devices from other manufacturers.
