Overview
The NCV8402STCT3G is a single-channel, low-side power switch IC manufactured by onsemi. It features an N-channel MOSFET output capable of delivering up to 2A continuous current with a typical on-resistance of 165 milliohms. The device supports load voltages up to 42V and operates within a junction temperature range of -40°C to 150°C. It includes integrated protection mechanisms such as fixed current limiting, overtemperature shutdown, and overvoltage protection, along with auto-restart functionality. The component is AEC-Q100 qualified for automotive applications and is housed in a SOT-223 (TO-261) surface-mount package.
Feature Summary
- Integrates comprehensive fault protection including fixed current limiting, thermal shutdown, and overvoltage detection.
- Features automatic restart capability following fault conditions to enhance system reliability.
- Designed for automotive environments with AEC-Q100 qualification and extended temperature operation.
Applications
- Automotive lighting control systems
- High-current load switching in vehicle electronics
- General purpose low-side power distribution
Procurement Notes
Verify the specific suffix 'STCT3G' against official manufacturer documentation to confirm tape-and-reel packaging quantities and lot traceability requirements. Ensure compatibility with standard SOT-223 footprint designs. Confirm RoHS compliance status for the specific production batch prior to integration into regulated assemblies.
Selection Notes
Select this component for applications requiring robust low-side switching with integrated protection. The 2A current rating and low on-resistance make it suitable for driving moderate loads efficiently. Verify that the 42V load voltage limit aligns with the system's maximum operating voltage under all transient conditions.
Part Context
This part belongs to the NCV8402 family of protected power switches from onsemi. The NCV prefix indicates automotive-grade qualification. The series is designed to simplify power management in harsh environments by combining switching capabilities with essential diagnostic and protection features in a compact package.
Replacement Considerations
Direct substitutes include other NCV8402 variants with different packaging options, such as NCV8402ASTT1G or NCV8402ASTT3G, provided the pinout and electrical specifications remain identical. Verify functional equivalence before substitution.
