NCV8415STT1G

Overview

The NCV8415STT1G is a self-protected low-side smart discrete FET from onsemi, designed for automotive power distribution. It features an N-channel MOSFET with integrated protection circuits including overcurrent, overtemperature, and delta thermal shutdown. The device operates at a maximum supply voltage of 40 V and supports a continuous load current of 11 A. Key electrical parameters include a maximum on-resistance (RDS(on)) of 21 mΩ and a gate threshold voltage optimized for low drive requirements. It is housed in a SOT-223 package and qualified to AEC-Q101 standards for automotive applications.

Feature Summary

• Integrated self-protection against overcurrent, overtemperature, and delta thermal events
• Optimized for high-voltage operation with fast switching capabilities
• Low gate resistance design for efficient drive requirements
• Built-in electrostatic discharge (ESD) protection

Applications

• Automotive lighting systems
• Power distribution units in vehicles
• Load switching for automotive peripherals
• High-current actuator control

Procurement Notes

Verify the specific suffix 'STT1G' to confirm the tape-and-reel packaging configuration and quantity per reel. Ensure the component meets AEC-Q101 qualification requirements for your target automotive application. Cross-reference the datasheet revision date to confirm compatibility with your design specifications. Confirm that the SOT-223 thermal pad soldering process aligns with your assembly guidelines for optimal heat dissipation.

Selection Notes

Select this component when a single-channel low-side switch with robust fault protection is required. It is suitable for applications needing up to 11 A continuous current with minimal external components. Consider the 21 mΩ RDS(on) for efficiency calculations in high-current paths. The AEC-Q101 qualification makes it appropriate for under-the-hood or chassis-mounted automotive electronics where reliability is critical.

Part Context

The NCV8415 belongs to onsemi's Smart Switch family of protected low-side drivers. These devices integrate power MOSFETs with control logic to simplify system design by reducing the need for external protection circuitry. The NCV8415 specifically targets automotive markets, offering a compact solution for managing high-power loads while providing diagnostic feedback through its protection features.

Replacement Considerations

Check for direct pin-compatible alternatives within the NCV84xx series or other onsemi low-side drivers with similar current ratings. Verify that any substitute matches the 40 V rating, 11 A current capacity, and AEC-Q101 qualification. Ensure the replacement maintains comparable RDS(on) and thermal performance characteristics.
