AZ23C3V0-E3-18

Overview

The AZ23C3V0-E3-18 is a dual common anode silicon planar Zener diode array from the Vishay AZ23 series, housed in a SOT-23 package. It features a nominal Zener voltage of 3.0 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 10 μA at 1 V and a dynamic resistance of 95 Ω at a test current of 5 mA.

Feature Summary

• Dual common anode configuration for space-efficient circuit designs
• High electrostatic discharge robustness per AEC-Q101 standards
• RoHS-compliant commercial grade construction

Applications

• Voltage reference circuits requiring dual low-voltage rails
• Input protection stages for sensitive electronic components
• Clamping applications in signal conditioning paths

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number against official Vishay documentation. Confirm that the ordering suffix matches the required reel quantity and packaging specifications. Ensure compliance with RoHS directives and check for any specific environmental or export control classifications relevant to the procurement region.

Selection Notes

Select this component when a dual Zener array with a common anode topology is required in a compact surface-mount footprint. Consider the 300 mW power dissipation limit on standard PCBs and the 95 Ω dynamic impedance for precision requirements. Verify that the 3.0 V nominal voltage aligns with the target circuit's clamping or reference needs.

Part Context

This part belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers various voltage options graded to the E24 standard, all packaged in the SOT-23 form factor. The 'E3' suffix indicates lead-free termination, while '-18' specifies the 10,000-unit reel packaging format.
