AZ23C3V9W-TP

Overview

The AZ23C3V9W-TP is a dual Zener diode array manufactured by Micro Commercial Components (MCC). It features a common anode configuration housed in an SOT-323 surface-mount package. The device provides a nominal Zener voltage of 3.9 V with a maximum power dissipation rating of 200 mW at 25°C ambient temperature. The manufacturing process ensures that the voltage difference (ΔVz) between the two diodes within the same case is less than or equal to 5%. The component operates within a junction temperature range of -65°C to +150°C and is designed for automatic insertion processes.

Feature Summary

• Dual Zener diodes integrated into a single compact SOT-323 package with a common anode configuration.
• Tight voltage matching capability where the deviation between the two internal diodes is maintained at 5% or less.
• Designed for high-volume automated assembly and insertion processes.
• Constructed with lead-free plating and halogen-free materials compliant with RoHS standards.

Applications

• Voltage reference circuits requiring matched dual voltage levels.
• Clamping and protection applications in portable electronic devices.
• Signal conditioning stages in automotive instrument clusters.
• Power supply regulation modules utilizing space-constrained PCB layouts.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and compliance status. Ensure the procurement channel provides original manufacturer documentation to validate authenticity. Check for any recent Product Change Notifications regarding assembly location or material composition updates before finalizing orders.

Selection Notes

Select this component when a matched pair of Zener diodes is required in a minimal footprint. The common anode topology simplifies circuit design compared to discrete components. Verify that the 200 mW power rating meets the thermal requirements of the target application environment. Confirm compatibility with standard SOT-323 land patterns during the PCB layout phase.

Part Context

This part belongs to the AZ23C series of dual Zener arrays from MCC. It shares the same physical package and general electrical characteristics as variants like the AZ23C3V6W-TP, differing primarily in the specific Zener voltage rating. The series is widely used in consumer electronics and industrial control systems where space efficiency and voltage stability are critical.

Replacement Considerations

Direct substitutes include other manufacturers' dual Zener arrays in SOT-323 packages with similar voltage ratings. Verify pinout compatibility and thermal resistance values before substitution. Cross-reference with equivalent parts from vendors such as Panjit or Taiwan Semiconductor if availability is constrained.
