SM4010N
AEC-Q101 qualified N-channel MOSFET with 40V VDS, 10A ID, and 15mΩ RDS(on) for automotive switching.
Product Overview
Description
The SM4010N is an automotive-grade N-channel MOSFET designed for power switching applications in vehicles. With a 40V drain-source voltage rating and 10A continuous current capability, it handles typical automotive loads with ease.
The low on-resistance of 15mΩ minimizes conduction losses and heat generation, improving system efficiency. The logic-level gate threshold allows direct drive from 3.3V or 5V MCUs.
AEC-Q101 qualification ensures reliable operation over the automotive temperature range. The device is available in SOP-8 and DPAK packages for different thermal requirements.

FAE Expert Insights
"The SM4010N is an excellent general-purpose automotive MOSFET. The 40V rating provides good margin for 12V automotive systems, and the 10A current capability handles most body control loads. The 15mΩ RDS(on) keeps losses low. I particularly like the logic-level gate drive - it works well with modern 3.3V MCUs without needing level shifters. The AEC-Q101 qualification gives confidence for automotive use. I've used this part in LED driver and motor control applications with excellent results."

Frequently Asked Questions
How do I calculate power dissipation in the MOSFET?
Power dissipation in MOSFET is calculated as P = I² × RDS(on) for conduction losses. For 10A current and 15mΩ RDS(on): P = 10² × 0.015 = 1.5W. Also consider switching losses at high frequencies. Ensure adequate PCB copper area for heat sinking - typically 1 square inch per watt.
