AZ23C33-TP

Overview

The AZ23C33-TP is a dual common anode Zener diode array manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 33 V with a 5% tolerance and a maximum power dissipation of 300 mW. The device operates within a temperature range of -55°C to +150°C and exhibits a voltage temperature coefficient of 0.09 %/°C. Key electrical parameters include a maximum reverse leakage current of 100 nA, a Zener impedance of 80 Ohms, and a test current of 5 mA. It is housed in an SOT-23-3 surface-mount package measuring 3.04 mm in length, 1.4 mm in width, and 1.1 mm in height.

Feature Summary

• Dual common anode configuration for space-efficient circuit design
• High operating temperature capability up to 150°C
• Low leakage current characteristics for precision applications

Applications

• Voltage reference circuits requiring dual polarity or split supplies
• Over-voltage protection stages in signal conditioning paths
• Clamping applications in high-temperature industrial environments

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the SOT-23-3 footprint matches the target PCB layout dimensions. Ensure the 300 mW power rating is sufficient for the intended thermal environment to prevent derating issues during operation.

Selection Notes

Select this component when a dual Zener solution is required in a compact SMD form factor. The 33 V nominal voltage and 5% tolerance suit moderate precision requirements. Consider the 80 Ohm impedance and 100 nA leakage limits against circuit sensitivity needs. The wide temperature range makes it suitable for automotive or industrial sectors where ambient conditions vary significantly.

Part Context

This part belongs to the AZ23C series of dual Zener arrays from MCC. It shares the SOT-23-3 package and common anode topology with other variants like the AZ23C12-TP and AZ23C3V3-TP. The series provides standardized solutions for multi-voltage reference and protection tasks in minimal board space.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing with other manufacturers requires independent verification of pinout compatibility, voltage tolerances, and thermal ratings.
