AZ23C7V5HE3-TP

Overview

The AZ23C7V5HE3-TP is a dual common anode Zener diode array manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 7.5 V with a tolerance of ±6%. The device is rated for a maximum power dissipation of 300 mW and operates within a junction temperature range of -55°C to +150°C. It is housed in a compact SOT-23 package, also identified as TO-236-3 or SC-59. The component meets AEC-Q101 automotive qualification standards. Key electrical characteristics include a maximum Zener impedance of 15 Ohms and a reverse leakage current of 1 µA at 5 V.

Feature Summary

• Dual common anode configuration integrates two Zener diodes into a single compact surface-mount package.
• Automotive-grade reliability achieved through AEC-Q101 qualification for robust performance in vehicle electronics.
• Low-profile SOT-23 packaging facilitates automated placement and efficient board space utilization.

Applications

• Voltage reference circuits in automotive instrument clusters
• Transient voltage suppression in digitally enhanced dashboards
• Signal conditioning and protection in real-time vehicle data systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and compliance status. Ensure the procurement channel provides valid traceability records. Confirm that the received components match the AEC-Q101 qualification requirements specified in the datasheet before integration into automotive designs.

Selection Notes

Select this component when a dual Zener solution is required in a minimal footprint for automotive applications. The 7.5 V nominal voltage and ±6% tolerance suit standard reference needs. Verify that the 300 mW power rating aligns with the thermal management capabilities of the target PCB layout and operating environment.

Part Context

This part belongs to the AZ23C series of dual Zener arrays from MCC. The HE3 designation typically indicates a halogen-free and RoHS-compliant variant within the product line. It serves as a specialized component for circuit protection and voltage regulation in constrained spaces typical of modern automotive electronic control units.

Replacement Considerations

Direct substitutes include the AZ23C7V5-TP and AZ23C7V5-E3-18. Verify pinout compatibility and electrical parameters such as Zener impedance and leakage current before substitution. Ensure any replacement maintains the required AEC-Q101 automotive qualification if used in certified vehicle systems.
