AZ23C3V6

Overview

The Taiwan Semiconductor AZ23C3V6 is a dual surface-mount Zener diode array housed in an SOT-23 package. It features a common anode configuration with two independent Zener junctions, each rated for a nominal voltage of 3.6 V and a tolerance of ±5%. The device dissipates up to 300 mW of power at 25°C ambient temperature and operates within a junction temperature range of -55°C to +150°C. Electrical characteristics include a maximum Zener impedance of 95 Ω at a test current of 5 mA and a leakage current of 1 µA at 2.7 V reverse bias.

Feature Summary

• Dual common anode configuration providing two independent Zener channels in a single compact package
• Designed for automated assembly processes with moisture sensitivity level 1 classification
• Halogen-free molding compound compliant with IEC 61249-2-21 standards

Applications

• Low voltage stabilizers or voltage references
• Adapters
• Lighting applications
• On-board DC/DC converters

Procurement Notes

Verify the specific ordering suffix (e.g., RFG) against the manufacturer's official documentation to confirm packaging details such as reel size and tape specifications. Ensure that the component meets RoHS compliance requirements and halogen-free status if mandated by the design specifications. Cross-reference the marking code KD4 on the physical device to confirm the correct part identification upon receipt.

Selection Notes

Select this component when a dual-channel voltage regulation solution is required in a space-constrained SOT-23 footprint. The common anode topology allows for efficient shared ground connections in differential signaling or dual-rail reference circuits. Verify that the 3.6 V nominal breakdown voltage aligns with the target circuit requirements and that the 300 mW power dissipation rating accommodates the expected thermal load under operating conditions.

Part Context

The AZ23C3V6 belongs to the broader AZ23C series manufactured by Taiwan Semiconductor Corporation, which offers a wide range of Zener voltages from 2.7 V to 51 V. This series is specifically engineered for surface-mount technology applications requiring reliable voltage clamping or reference functions. The consistent SOT-23 form factor across the series facilitates standardized PCB layout designs for various voltage levels.

Replacement Considerations

Direct substitutes within the same family include other AZ23C variants with different voltage ratings, such as AZ23C3V0 or AZ23C3V9, provided the voltage specification matches the application needs. External replacements must match the SOT-23 package, dual common anode configuration, and equivalent electrical parameters including power dissipation and impedance.
