AZ23C18-TP

Overview

The AZ23C18-TP is a dual common anode Zener diode array manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 18 V with a tolerance of ±5%. The device has a maximum power dissipation of 300 mW and operates within a junction temperature range of -55°C to +150°C. Key electrical parameters include a maximum reverse leakage current of 100 nA, a Zener impedance of 45 Ohms, and a test current of 5 mA. It is housed in a surface-mount SOT-23-3 package.

Feature Summary

• Dual common anode configuration for space-efficient circuit design
• Surface-mount SOT-23-3 packaging for automated assembly
• Wide operating temperature range suitable for industrial environments

Applications

• Voltage reference circuits requiring dual stable potentials
• Clamping and protection stages in signal conditioning paths
• Biasing networks in analog integrated circuits

Procurement Notes

Verify the specific suffix against official MCC documentation to confirm pinout and electrical tolerances. Ensure the component matches the required Zener voltage and power dissipation ratings for the target application. Cross-reference datasheets from authorized distributors to validate RoHS compliance and packaging details before procurement.

Selection Notes

Select this component when a dual Zener solution with a common anode is required in a compact SOT-23 footprint. Consider the 45 Ohm impedance and 100 nA leakage current limits during thermal and noise analysis. Verify that the 300 mW power rating accommodates the expected operating current and ambient temperature conditions without exceeding the maximum junction temperature.
