AZ23C36HE3-TP

Overview

The AZ23C36HE3-TP is a dual common anode Zener diode array manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 36 V with a maximum power dissipation of 300 mW. The device operates within a junction temperature range of -55°C to +150°C and carries AEC-Q101 automotive qualification. Key electrical parameters include a maximum reverse leakage current of 100 nA at 25.2 V, a Zener impedance of 90 Ohms, and a tolerance of ±5.56%. It is housed in a compact SOT-23 surface-mount package.

Feature Summary

• Dual common anode configuration for space-efficient circuit design
• Automotive-grade reliability certified under AEC-Q101 standards
• Wide operating temperature range suitable for harsh environments

Applications

• Voltage reference circuits in automotive electronics
• Transient voltage suppression in signal conditioning paths
• Over-voltage protection for sensitive semiconductor components

Procurement Notes

Verify the specific suffix HE3 indicates halogen-free compliance when sourcing. Confirm the package type matches the required footprint, as variations exist between SOT-23 and similar small outline packages. Ensure the supplier provides valid traceability documentation for automotive grade parts. Check for recent production change notices that may affect packaging or material composition.

Selection Notes

Select this component when a dual Zener solution is required in a minimal footprint. The 36 V rating suits applications needing precise voltage clamping above standard logic levels. Consider the 300 mW power rating against expected surge currents. The AEC-Q101 certification makes it appropriate for automotive systems where long-term stability and thermal resilience are critical requirements.

Part Context

This part belongs to the AZ23C series of dual Zener arrays from MCC. It shares the same internal structure as the AZ23C36W-TP but differs in power handling and package style. The HE3 designation typically denotes environmental compliance features within the manufacturer's portfolio. It serves as a compact alternative to discrete dual-diode implementations.

Replacement Considerations

Direct substitutes include other dual common anode Zener arrays with matching 36 V ratings and SOT-23 footprints. Verify pinout compatibility before substitution. Alternative packages like SC-70 may require schematic revision. Ensure replacement parts meet the same AEC-Q101 automotive qualification if used in vehicle systems.
