AZ23C3V6WHE3-TP

Overview

The AZ23C3V6WHE3-TP is a dual Zener diode array manufactured by Micro Commercial Components (MCC). It features two common anode Zener diodes integrated into a single SOT-323 surface-mount package. The nominal Zener voltage is 3.6 V with a tolerance of ±5%. Each diode supports a maximum power dissipation of 200 mW at 25°C ambient temperature. The device operates within a junction temperature range of -65°C to +150°C and exhibits a maximum dynamic impedance of 95 Ohms at a test current of 5 mA.

Feature Summary

• Dual Zener configuration in a compact SOT-323 package
• Common anode topology for simplified circuit design
• Automotive-grade reliability via AEC-Q101 qualification
• Halogen-free construction compliant with environmental standards

Applications

• Voltage reference circuits requiring dual stable potentials
• Clamping and protection stages in signal conditioning paths
• Biasing networks in low-power analog applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm compliance with automotive qualification standards and halogen-free material requirements. Ensure that the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability of the component batch.

Selection Notes

Select this component when a dual Zener solution with a common anode is required in a space-constrained SOT-323 footprint. The 3.6 V nominal voltage and 200 mW power rating make it suitable for low-current regulation tasks. Confirm that the 95 Ohm dynamic impedance meets the noise and stability requirements of the target application circuit.

Part Context

This part belongs to the AZ23C series of dual Zener arrays from MCC, designed for surface-mount assembly. The HE3 suffix typically indicates enhanced environmental specifications, such as halogen-free status, while the TP suffix denotes tape-and-reel packaging. It serves as a compact alternative to discrete dual-diode implementations.

Replacement Considerations

Direct substitutes include the DZ23C3V6-TP and AZ23C3V6W-TP from MCC, which share similar electrical characteristics and pin configurations. Cross-manufacturer equivalents like the BZX84C3V6LT1 are available but differ in package type and may require schematic adjustments.
