AZ23C3V9-TP

Overview

The AZ23C3V9-TP is a dual common anode Zener diode array manufactured by Micro Commercial Components. It features a nominal Zener voltage of 3.9 V with a tolerance of ±5%. The device operates within a power dissipation rating of 300 mW and maintains a maximum reverse leakage current of 100 nA at 7 V. Electrical characteristics include a Zener impedance of 95 Ohms measured at a test current of 5 mA. The component supports an operating temperature range from -55°C to +150°C junction temperature and is housed in a compact SOT-23-3 surface-mount package.

Feature Summary

• Dual Zener diodes integrated into a single common anode configuration for space-efficient circuit design.
• Compact SOT-23-3 surface-mount package suitable for automated insertion and high-density PCB layouts.
• Wide thermal operating range supporting reliable performance across extreme industrial temperatures.

Applications

• Voltage reference circuits requiring stable dual supply rails.
• Clamping and protection stages in signal conditioning paths.
• Biasing networks in low-power analog interfaces.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to ensure correct packaging and compliance status. Confirm that the requested variant matches the required electrical tolerances and thermal ratings for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener solution with a common anode topology is required in a small footprint. Ensure the 300 mW power dissipation limit accommodates the expected thermal load. Verify that the 3.9 V breakdown voltage aligns with the system's reference or clamping requirements.

Part Context

This part belongs to the AZ23C series of dual Zener arrays produced by Micro Commercial Components. The series offers various voltage options within the same SOT-23-3 package, allowing designers to standardize on a single package type while adjusting voltage levels through different model suffixes.

Replacement Considerations

Direct substitutes include other manufacturers' dual common anode Zener arrays in SOT-23 packages with matching 3.9 V specifications. Verify pinout compatibility and thermal resistance values before substitution.
