AZ23C3V0-G3-18

Overview

The AZ23C3V0-G3-18 is a silicon planar Zener diode array from the AZ23-G series, 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 3.0 V with a ±5% tolerance. Electrical characteristics include a maximum reverse leakage current of 10 μA at 1 V and a dynamic resistance of 95 Ω at a test current of 5 mA. The device supports a junction temperature up to 150 °C and operates within a range of -55 °C to +150 °C.

Feature Summary

• Dual common anode configuration for integrated circuit protection
• Silicon planar construction ensuring robust performance
• ESD capability exceeding 8 kV (HBM) and 800 V (MM)
• RoHS compliant commercial grade material categorization

Applications

• Voltage reference applications requiring dual polarity or split supplies
• Input/output protection in portable electronic devices
• Clamping circuits in signal conditioning paths

Procurement Notes

Verify the specific ordering code suffix against project requirements. The '-18' suffix indicates a standard 10,000-unit reel packaging format on a 13-inch tape. Confirm that the ±5% tolerance designation ('C') aligns with the design specifications before finalizing procurement orders.

Selection Notes

Select this component when a dual common anode topology is required for space-constrained designs. The SOT-23 package offers a compact footprint suitable for high-density PCB layouts. Ensure the 300 mW power dissipation limit on an FR-4 board meets the thermal requirements of the target application environment.

Part Context

This part belongs to the AZ23-G series of small signal Zener diodes. The series provides a wide range of Zener voltages from 2.2 V to 75 V. Variants are available with different tolerances, where 'B' denotes ±2% and 'C' denotes ±5%. The series is designed for general-purpose switching and clamping applications in consumer and industrial electronics.

Replacement Considerations

Parametric equivalents within the same manufacturer family include AZ23C3V0-E3-18 and AZ23C3V0-G3-08. Verify pinout compatibility and electrical parameter alignment before substitution. Cross-manufacturer replacements require validation of package dimensions and thermal characteristics.
