NCV8406STCT1G

Overview

The NCV8406STCT1G is a self-protected low-side driver manufactured by onsemi, designed for automotive applications. It features a single N-channel output capable of handling up to 7 A continuous drain current with a 65 V breakdown voltage. The device integrates fixed current limiting, overtemperature protection, and overvoltage protection with auto-restart functionality. Packaged in an SOT-223-4 surface-mount configuration, it operates within a junction temperature range of -40°C to +150°C and holds AEC-Q100 qualification.

Feature Summary

• Integrates fixed current limit, overtemperature, and overvoltage protection with automatic restart capability
• Single N-channel low-side switch architecture for direct load control
• AEC-Q100 qualified for automotive reliability standards
• Surface-mount SOT-223-4 package optimized for thermal performance

Applications

• Automotive lighting systems
• Solenoid and relay drivers
• Fan and pump motor control
• General purpose load switching in vehicle ECUs

Procurement Notes

Verify the exact suffix against official onsemi documentation, as distribution listings may vary. Confirm AEC-Q100 compliance requirements match your specific application grade. Ensure the SOT-223-4 footprint aligns with your PCB design guidelines. Cross-reference the datasheet revision date to ensure all electrical parameters are current before finalizing procurement specifications.

Selection Notes

Select this component when a robust, single-channel low-side driver with integrated fault protection is required. It is suitable for loads drawing up to 7 A where space constraints favor the SOT-223-4 package. Consider alternative models from the NCV840x series if higher current capacity or high-side switching topology is needed instead of the low-side configuration provided here.

Part Context

This part belongs to the NCV8406A family of self-protected low-side drivers from onsemi. These devices are engineered specifically for automotive environments, offering high reliability and compact integration. The family typically includes variants with different current ratings and packaging options, all sharing common protection features like thermal shutdown and current limiting for safe operation.

Replacement Considerations

Direct substitutes include other NCV8406A variants such as NCV8406ASTT1G or NCV8406ASTT3G, which share identical electrical characteristics and pinouts but differ in reel quantities. Verify that any replacement maintains the same SOT-223-4 package and AEC-Q100 qualification status.
