AZ23C8V2-E3-18

Overview

The AZ23C8V2-E3-18 is a silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a dual common anode configuration within a SOT-23 surface-mount package. The nominal Zener voltage is 8.2 V with a tolerance of ±5%, tested at a current of 5 mA. Maximum reverse leakage current is specified as 0.1 µA at 6 V, and dynamic resistance is 7 Ω at the test current. The device supports a maximum power dissipation of 300 mW on an FR-4 board and operates across a temperature range of -55 °C to +150 °C.

Feature Summary

• Dual common anode circuit configuration for space-efficient designs
• ESD protection capability exceeding 8 kV via human body model
• RoHS-compliant commercial grade construction

Applications

• Voltage reference circuits requiring dual polarity or split supplies
• Clamping applications in signal conditioning paths
• Overvoltage protection for sensitive input stages

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm tape-and-reel specifications and minimum order quantities. Ensure that the component marking code D53 aligns with the required visual identification standards for your assembly process before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener array with a common anode topology is required in a compact SOT-23 footprint. The ±5% voltage tolerance suits general-purpose regulation tasks where tight precision is not critical. Consider the thermal resistance characteristics if operating near the upper limits of the specified junction temperature range.

Part Context

This part belongs to the AZ23 series of small signal Zener diodes from Vishay Semiconductors. The series offers a wide range of graded Zener voltages according to the international E24 standard. Variants are available with different tolerances and AEC-Q101 automotive qualifications depending on the specific ordering code suffixes.

Replacement Considerations

Direct parameter-equivalent replacements within the same family include AZ23B8V2-E3-18, which provides tighter ±2% voltage tolerance while maintaining identical electrical ratings and packaging.
