AZ23C3V9HE3-TP

Overview

The AZ23C3V9HE3-TP is a dual common anode Zener diode array manufactured by Micro Commercial Components (MCC). It integrates two independent Zener diodes within a single SOT-23-3 surface-mount package. The device provides a nominal Zener voltage of 3.9 V with a tolerance of 5%. It supports a maximum power dissipation of 300 mW and operates across a temperature range from -55°C to +150°C junction temperature. Key electrical parameters include a test current of 5 mA, a maximum reverse leakage current of 5 mA, and a Zener impedance of 95 Ohms at the test current.

Feature Summary

• Dual common anode configuration for space-efficient circuit design
• Automated assembly suitability with standard SMD packaging
• RoHS compliant construction with halogen-free materials

Applications

• Voltage reference circuits requiring matched dual channels
• Clamping and protection stages in signal processing paths
• Biasing networks in portable electronic devices

Procurement Notes

Verify the specific suffix HE3 against the manufacturer's latest datasheet to confirm compliance with RoHS directives and halogen-free status. Confirm that the SOT-23-3 footprint matches the target PCB layout dimensions. Ensure the 300 mW power rating aligns with the thermal management capabilities of the final application environment.

Selection Notes

Select this component when a dual Zener solution with common anode topology is required in a compact SOT-23-3 package. The 3.9 V nominal voltage and 5% tolerance suit precision reference applications. Consider the 95 Ohm impedance value for high-frequency noise filtering requirements. Verify availability as distribution status may vary by region.

Part Context

This part belongs to the AZ23C series of dual Zener arrays from MCC. It shares the physical SOT-23-3 footprint with variants offering different voltage ratings such as AZ23C3V6HE3-TP and AZ23C8V2HE3-TP. The series is designed for automated surface-mount production processes.

Replacement Considerations

Cross-reference with AZ23C3V9-TP for identical electrical specifications but verify if the HE3 suffix denotes specific environmental compliance differences. Check equivalent offerings from other manufacturers in the SOT-23-3 dual Zener category.
