NCV8402STCT1G

Overview

The NCV8402STCT1G is a self-protected low-side driver manufactured by onsemi, designed for automotive applications. It integrates an N-channel MOSFET with control logic in a SOT-223 (TO-261) package. The device supports a maximum load voltage of 42V and delivers a continuous output current of 2A. Key electrical parameters include a typical on-resistance of 165 mΩ and a gate-source voltage range of ±14V. It operates within a junction temperature range of -40°C to 150°C and holds AEC-Q100 qualification.

Feature Summary

Integrates overcurrent protection with fixed current limit and thermal shutdown capabilities
Features automatic restart functionality following fault conditions
Includes overvoltage protection mechanisms for robust load handling

Applications

Automotive lighting systems
Solenoid and relay driving
General purpose low-side switching

Procurement Notes

Verify the specific suffix STCT1G against official datasheets to confirm the tape-and-reel packaging configuration. Ensure compatibility with AEC-Q100 automotive standards if used in vehicle electronics. Cross-reference pinouts with similar variants like NCV8402ASTT1G only if explicitly documented as interchangeable. Confirm RoHS compliance status through manufacturer declarations prior to integration.

Selection Notes

Select this component for applications requiring integrated protection in a compact surface-mount package. The 42V rating suits standard automotive electrical systems. Consider the 165 mΩ on-resistance for power dissipation calculations. Verify that the single-channel output meets the circuit requirements without needing additional drivers.

Part Context
