Its key parametric is a maximum on-resistance of 10.5 mOhm at 20A drain current with a 10V gate drive, which keeps conduction losses low in switching applications like DC-DC converters, load switches, and motor drive bridges. The STD50N03L is listed as obsolete per the manufacturer's product status. Drive voltage range is 5V to 10V. ## Temperature range and package — deployment context In practice, continuous operation near 175°C requires careful derating of the 40A current rating — the 40A figure is at 25°C case temperature, and the current must be reduced at higher temperatures per the datasheet's thermal derating curve.","metaTitle":"STD50N03L N-Channel MOSFET, 30V, 40A, DPAK, Obsolete","metaDescription":"STMicroelectronics STD50N03L N-channel MOSFET, 30V Vdss, 40A Id, 10.5mOhm Rds(on) at 10V.
