AZ23C22HE3-TP

Overview

The AZ23C22HE3-TP is a dual common anode Zener diode array manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 22 V with a tolerance of ±5%. The device has a maximum power dissipation of 300 mW and operates within a junction temperature range of -55°C to +150°C. Key electrical characteristics include a maximum reverse leakage current of 100 nA at 17 V and a Zener impedance of 55 Ohms. The component is housed in an SOT-23 package.

Feature Summary

• Dual common anode configuration for space-efficient circuit design
• Automotive-grade reliability with AEC-Q101 qualification
• Surface-mount SOT-23 packaging for automated assembly

Applications

• Voltage reference circuits requiring dual stable potentials
• Clamping and protection stages in automotive electronics
• Signal conditioning modules in industrial control systems

Procurement Notes

Verify the specific suffix HE3 indicates halogen-free compliance when sourcing. Confirm the manufacturer part number matches exactly, as variations exist within the AZ23 series. Check official distributor catalogs for current availability status, as stock levels fluctuate. Ensure the ordering quantity aligns with standard reel or cut-tape specifications provided by the supplier.

Selection Notes

Select this component when a dual Zener solution with common anode topology is required in a compact footprint. The 22 V nominal voltage suits applications needing precise regulation near that threshold. Consider the 300 mW power rating for thermal management constraints. Verify compatibility with surface-mount assembly processes due to the SOT-23 form factor.

Part Context

This part belongs to the AZ23C series of dual Zener arrays from MCC. It shares the SOT-23 package with other variants like AZ23C2V7HE3-TP and AZ23C8V2HE3-TP. The series offers various voltage options while maintaining consistent electrical characteristics and packaging standards for interchangeable design platforms.

Replacement Considerations

AZ23C22-G3-18 from Vishay General Semiconductor is a parameter-equivalent alternative. Both parts share the 22 V Zener voltage, 300 mW power rating, and SOT-23-3 package. Verify pinout compatibility and exact tolerance specifications before substitution.
