AZ23C7V5-G3-08

Overview

The AZ23C7V5-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 7.5 V with a ±5% tolerance (indicated by 'C'). Electrical testing occurs at a test current of 5 mA, yielding a maximum dynamic resistance of 7 Ω and a reverse leakage current of 100 nA at 5 V. The device operates within a temperature range of -55 °C to +150 °C and dissipates up to 300 mW on an FR-4 board.

Feature Summary

• Dual common anode configuration for space-efficient circuit design
• Zener voltages graded according to 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 signal lines
• Clamping applications in low-power electronic systems

Procurement Notes

Verify the specific ordering suffix against official documentation before procurement. Confirm that the component meets RoHS3 compliance requirements and matches the intended tape-and-reel packaging format. Ensure the supplier source aligns with authorized distribution channels to guarantee authenticity and traceability.

Selection Notes

Select this part when a dual Zener solution with a common anode is required in a compact SOT-23 footprint. The ±5% tolerance suits general-purpose regulation tasks. Verify that the 7.5 V nominal voltage and 300 mW power dissipation meet the thermal and electrical constraints of the target application environment.

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 Zener voltages from 2.2 V to 75 V in both 5% ('C') and 2% ('B') tolerance grades. All variants share identical physical dimensions and pin configurations, facilitating interchangeable layout designs across different voltage requirements.

Replacement Considerations

Direct replacements include other AZ23C7V5 variants such as AZ23C7V5-E3-08 or AZ23C7V5-G3-18, which maintain the same electrical characteristics but differ in packaging quantities or lead-free status. Cross-brand equivalents require matching the SOT-23-3 package, 7.5 V nominal voltage, and common anode topology.
