AZ23C4V3WHE3-TP

Overview

The AZ23C4V3WHE3-TP is a dual common anode Zener diode manufactured by Micro Commercial Components (MCC). It integrates two independent Zener elements within a single SOT-23 package. The device provides a nominal Zener voltage of 4.3 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. The component features a maximum reverse leakage current of 100 nA at 32 V and a Zener impedance of 95 Ohms at a test current of 5 mA. It is RoHS compliant and lead-free.

Feature Summary

• Dual common anode configuration for space-efficient circuit design
• High thermal stability with extended operating temperature range
• Lead-free construction compliant with environmental standards

Applications

• Voltage reference circuits requiring dual rails
• Clamping and protection in signal processing paths
• Biasing networks in low-power electronic devices

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout and electrical tolerances. Ensure compatibility with surface mount assembly processes. Confirm RoHS compliance status through the latest product documentation before integration into regulated products.

Selection Notes

Select this component when a dual Zener solution is required in a compact SOT-23 footprint. Verify that the 4.3 V breakdown voltage aligns with circuit requirements. Consider the 300 mW power rating for thermal management in dense layouts.

Part Context

This part belongs to the AZ23C series of dual Zener diodes from MCC. It shares the SOT-23 package form factor with other variants in the family, differing primarily in Zener voltage ratings and specific electrical characteristics defined by the model number.

Replacement Considerations

Cross-reference with AZ23C4V3 from Taiwan Semiconductor or AZ23C4V3-7-F from Diodes Incorporated for functional equivalents. Verify package dimensions and pin configurations match the target PCB layout.
