NCV8406ASTT1G

Overview

The NCV8406ASTT1G is a single N-channel low-side smart switch manufactured by onsemi. It operates with a drain-source voltage of 65 V and supports a continuous drain current of 7 A. The device features an on-resistance of 210 mOhms and a gate-source voltage range of -14 V to 14 V, with a threshold voltage of 2 V. It dissipates up to 1.25 W of power and functions within a temperature range of -40°C to +150°C. The component is housed in a SOT-223-4 package and meets AEC-Q100 automotive qualification standards.

Feature Summary

• Integrated overcurrent protection with short circuit capability
• Thermal shutdown with automatic restart functionality
• Overvoltage protection via integrated Drain-to-Gate clamping
• ESD protection and dV/dt robustness for harsh environments

Applications

• Switching resistive, inductive, and capacitive loads
• Replacing electromechanical relays in automotive systems
• Industrial load control applications

Procurement Notes

Verify the specific suffix TT1G confirms the SOT-223-4 tape and reel packaging configuration. Confirm AEC-Q100 qualification status aligns with project requirements. Ensure thermal management design accounts for the 1.25 W power dissipation limit in the selected enclosure environment.

Selection Notes

Select this component for low-side switching applications requiring high current handling up to 7 A. The 65 V rating suits standard automotive electrical systems. Consider the SOT-223-4 package for surface mount assembly. Verify logic-level input compatibility for direct microcontroller interfacing without additional drive circuitry.

Part Context

This part belongs to the NCV8406A series of self-protected low-side drivers. It is designed as a discrete replacement for complex relay circuits. The NCV prefix indicates automotive-grade manufacturing controls. It provides a compact solution for managing high-power loads in space-constrained electronic assemblies.

Replacement Considerations

NCV8406ASTT3G offers identical electrical specifications but utilizes a different factory reel quantity.
