NCV8402MNWCT1G

Overview

The NCV8402MNWCT1G is a single-channel, low-side smart power switch manufactured by onsemi. It integrates an N-channel MOSFET with control logic in a compact DFN-6 package. The device features a drain-source breakdown voltage (Vds) of 42 V and supports a continuous drain current (Id) of 2 A. Its typical on-resistance (Rds(on)) is 165 mΩ. The gate-source voltage range is -14 V to +14 V, with a threshold voltage (Vgs(th)) of 1.3 V. It operates within a temperature range of -40°C to +150°C and has a power dissipation (Pd) of 8.9 W. The component is qualified under the AEC-Q101 standard for automotive applications.

Feature Summary

• Integrates a low-side N-channel MOSFET with driver logic for simplified system design
• Provides robust protection against over-current and thermal overload conditions
• Complies with AEC-Q101 automotive qualification standards for reliability

Applications

• Automotive lighting systems
• Solenoid and relay driving circuits
• General-purpose load switching in vehicle electronics

Procurement Notes

Verify the specific suffix 'CT1G' corresponds to the Cut Tape packaging variant when ordering. Confirm that the AEC-Q101 qualification aligns with your project's automotive grade requirements. Ensure the DFN-6 footprint matches your PCB layout constraints. Cross-reference the datasheet revision date to confirm technical specifications have not changed. Validate supply chain authenticity through authorized distributors.

Selection Notes

Select this component for applications requiring a single low-side switch with integrated protection in a small form factor. Compare the 165 mΩ on-resistance against thermal management capabilities in your enclosure. Consider the 2 A current limit for load compatibility. Evaluate the DFN-6 package for soldering feasibility versus alternative packages like SOT-223 if higher power dissipation is needed.

Part Context

This part belongs to the NCV8402A series of smart power switches from onsemi. The series includes variants with different packages such as SOT-223 and SOIC-8, offering flexibility in thermal and spatial design.
