It is built on the HEXFET trench technology and carries AEC-Q101 qualification, making it suited for under-hood automotive loads such as electric power steering, DC-DC converters, and motor-drive pre-drive stages where junction temperatures can reach 175 °C. The 4.9 mOhm maximum on-resistance at 75 A and 10 V gate drive keeps conduction losses low in high-current paths. ## Rds(on) and gate charge — what they mean for the switching loop The 4.9 mOhm Rds(on) is specified at 75 A with 10 V gate drive — that is the operating point where the MOSFET is fully enhanced. The 180 nC total gate charge at 10 V means the gate driver must supply 180 nC per switching cycle. ## 175 °C junction — where it matters Rated for -55 °C to 175 °C junction temperature, this part handles the thermal cycling of engine-bay environments and high-ambient industrial enclosures. The 175 °C Tj max is the absolute limit for the silicon. ## Lifecycle and sourcing Listed as Active by the manufacturer, so there is no imminent last-time-buy or EOL risk.
