AZ23C8V2-G3-18

Overview

The AZ23C8V2-G3-18 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 8.2 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 at 25 °C include a reverse leakage current of 0.1 μA at 6 V, a dynamic resistance of 7 Ω at 5 mA, and a temperature coefficient ranging from 4 to 7 × 10⁻⁴/°C.

Feature Summary

• Dual common anode configuration for space-efficient circuit design
• ESD capability compliant with AEC-Q101 standards
• Green commercial grade construction without halogenated additives

Applications

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

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's part number against official datasheets and authorized distributor channels. Confirm that the ordering suffix matches the required tape-and-reel quantity and packaging specifications. Ensure compliance with RoHS directives and material categorization requirements before finalizing procurement orders.

Selection Notes

Select this variant when a dual common anode topology is required alongside specific 8.2 V regulation needs. The ±5% tolerance suits general-purpose applications where tighter precision is unnecessary. Evaluate thermal constraints carefully, as the 300 mW rating depends on the recommended soldering footprint on FR-4 substrates.

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 graded Zener voltages from 2.2 V to 75 V, utilizing standard E24 values. The 'C' designation indicates the 5% voltage tolerance tier, while the 'G3' suffix denotes green, commercial-grade packaging.

Replacement Considerations

AZ23B8V2-G3-18 provides identical electrical functionality with a tighter ±2% voltage tolerance.
