NCV8402ASTT1G
onsemiNCV8402ASTT1G is an onsemi self-protected low-side driver in a SOT-223 (TO-261-4) package, tape and reel, with a 42 V drain clamp, typical RDS(on) of 165 milliohms at 10 V gate drive, maximum drain current of 2.0 A, and integrated overcurrent and overtemperature shutdown with auto-restart, overvoltage clamping and ESD protection. Selection advice: the current onsemi datasheet for the merged NCV8402/NCV8402A family prints this exact code in a SOT-223 package - older revisions of the datasheet did not include the A variant, and the DPAK-4 package sometimes attached to this code in listings belongs to other family members, so confirm against the current datasheet revision before layout. For body relays, lamps and solenoids it replaces a relay plus discrete MOSFET plus protection network; the NCV prefix denotes AEC-Q101 qualification with PPAP capability. Parameters verified against onsemi documentation.

NCV8402ASTT1G FAQ
What should I check before substituting NCV8402ASTT1G with another protected low-side switch?
Match the full ordering code, not the series name: package (SOT-223), temperature grade and packing all ride on the suffixes. A same-series code in a different package is a different orderable device, so confirm the substitute against the onsemi datasheet before changing the BOM.
