NCV8401ADTRKG

Overview

The NCV8401ADTRKG is a self-protected low-side smart discrete device manufactured by onsemi. It integrates a power MOSFET with comprehensive protection circuitry, including overcurrent, overtemperature, ESD, and integrated drain-to-gate clamping for overvoltage protection. Designed for harsh automotive environments, it features AEC-Q101 qualification and PPAP capability. The component operates within a junction temperature range of -40°C to +150°C and utilizes a DPAK-3 (TO-252-3) surface-mount package. It offers analog drive capability via a logic-level input and provides dV/dt robustness.
