Overview
The NCV8402AMNWT1G is a single-channel, low-side smart power switch manufactured by onsemi. It integrates an N-channel MOSFET with control and protection logic in a compact 6-DFN package. The device supports a drain-source voltage of 42 V and delivers a continuous current of 2 A. Its typical on-resistance is 165 mOhms, ensuring efficient power handling. The component operates within a junction temperature range of -40°C to +150°C and meets AEC-Q101 automotive qualification standards for reliability.
Feature Summary
- Integrates overvoltage, overtemperature, and fixed current limit protection with auto-restart functionality
- Features a low on-resistance N-channel MOSFET for efficient load switching
- Designed for automotive applications with AEC-Q101 qualification
Applications
- Automotive lighting systems
- Solenoid and relay driver circuits
- Low-side load switching in vehicle electronics
Procurement Notes
Verify the specific suffix MNWT1G against official datasheets to confirm the DFN-6 package and reel packaging configuration. Ensure compatibility with AEC-Q101 requirements if used in automotive designs. Cross-reference ordering information with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status prior to procurement.
Selection Notes
Select this component when a robust, single-channel low-side switch is required for automotive loads. The 165 mOhm resistance suits moderate current applications up to 2 A. Consider the 6-DFN footprint for space-constrained PCB layouts. Verify thermal management capabilities given the 8.9 W power dissipation rating in the specified package.
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. These devices are engineered for high-reliability automotive environments, offering integrated protection features that simplify circuit design compared to discrete MOSFET solutions.
Replacement Considerations
Check for direct substitutes like NCV8402ASTT1G or NCV8402ADDR2G. Note that these alternatives may differ in package type (SOT-223 or SOIC) and pinout compatibility. Verify electrical parameters match before substitution.
