DZ23C18-TP

Overview

The DZ23C18-TP is a dual common cathode Zener diode array manufactured by Micro Commercial Components. It operates within a surface-mount SOT-23-3 package, measuring 3.04 mm in length, 1.4 mm in width, and 1.12 mm in height. The device provides a nominal Zener voltage of 18 V with a tolerance of ±5%. Rated for a maximum power dissipation of 300 mW, it functions at a test current of 5 mA. The component supports an operating temperature range from -55°C to +150°C and exhibits a maximum reverse leakage current of 100 nA.

Feature Summary

• Dual common cathode configuration integrates two independent Zener diodes into a single compact footprint.
• Surface-mount construction utilizes the standard SOT-23-3 package for automated assembly compatibility.
• Wide thermal operating range ensures stability across extreme environmental conditions.

Applications

• Voltage reference circuits requiring dual stable potential sources
• Transient voltage suppression in low-power signal lines
• Clamping applications in portable electronic devices

Procurement Notes

Verify the specific datasheet version before ordering, as manufacturing changes may occur. Confirm that the SOT-23-3 package dimensions match your PCB footprint requirements. Ensure the 300 mW power rating aligns with your circuit's thermal design constraints. Check RoHS compliance documentation if required by your regional regulations. Validate the dual common cathode configuration against your schematic needs.

Selection Notes

Select this component when a dual Zener solution is needed in a minimal space-constrained layout. The 18 V nominal voltage suits applications requiring moderate reference levels. Consider the 100 nA leakage current limit for high-impedance circuits. The wide temperature range makes it suitable for industrial or automotive environments where thermal stability is critical.

Part Context

This part belongs to the DZ23C series of dual Zener arrays from Micro Commercial Components. Similar variants include DZ23C15-TP and DZ23C39-TP, which share the same package and power characteristics but differ in Zener voltage ratings. The series is designed for general-purpose voltage regulation and protection tasks.
