AZ23B39HE3-TP

Overview

The AZ23B39HE3-TP is a dual common anode Zener diode manufactured by Micro Commercial Components (MCC). It integrates two independent Zener diodes within a single SOT-23-3 surface-mount package. The device features a nominal Zener voltage of 39 V with a maximum power dissipation of 300 mW. Electrical characteristics include a maximum reverse leakage current of 5 uA and a Zener impedance of 100 Ohms at a test current of 5 mA. The component operates reliably across a temperature range from -55 C to +150 C, ensuring stable performance in demanding electronic environments.

Feature Summary

• Dual common anode configuration allows for compact circuit design using a single three-terminal package.
• SOT-23-3 surface-mount footprint facilitates automated assembly and space-constrained applications.
• Wide operating temperature range supports functionality in extreme thermal conditions.

Applications

• Voltage reference circuits requiring dual independent references
• Clamping and protection stages in signal processing paths
• Biasing networks in analog integrated circuits

Procurement Notes

Verify the specific ordering suffix HE3-TP against official MCC documentation to confirm RoHS compliance and tape-and-reel packaging specifications. Ensure that the requested quantity aligns with standard factory pack sizes, typically 3000 units per reel, to avoid partial reel handling issues during procurement.

Selection Notes

Select this component when a dual Zener solution with a common anode is required in a minimal footprint. Confirm that the 39 V breakdown voltage matches the target circuit requirements and that the 300 mW power rating provides sufficient margin for the expected operational current. Verify compatibility with SOT-23-3 land patterns.

Part Context

This part belongs to the AZ23B series of dual Zener diodes from Micro Commercial Components. The series offers various voltage options within the same SOT-23-3 package, allowing designers to maintain consistent board layouts while adjusting voltage parameters. The HE3-TP designation indicates Halogen-free and RoHS-compliant construction with specific trailing edge packaging.

Replacement Considerations

Cross-reference with other AZ23B39 variants from different manufacturers if supply constraints exist. Ensure that substitute parts match the SOT-23-3 pinout, specifically the common anode configuration, and verify equivalent electrical parameters such as Zener impedance and leakage current.
