The typical on-resistance of 160 mOhm sets the conduction loss floor for the channel — at 1.8 A the resistive drop is about 290 mV, which matters for the voltage headroom at the load when the supply rail is near its lower limit. The switch integrates a full set of fault protections: current limiting (fixed), open-load detection, over-temperature shutdown, over-voltage clamp, and under-voltage lockout. These cover the common failure modes in a switched-load channel without external supervisory components. ## 160 mOhm Rds(on) and 1.8 A output — thermal budget The 160 mOhm typical Rds(on) is the value at 25 °C junction; expect the on-resistance to rise with temperature per the normalised curve in the datasheet. For a 1.8 A continuous load, the I²R conduction loss at 25 °C is about 0.52 W. In the TO-263-5 (D²Pak) package, the copper area on the drain tab sets the junction-to-ambient thermal resistance — a 1 in² pad keeps the junction rise within the -40°C to 150°C operating range for most ambient conditions.","metaTitle":"Infineon BTS409L1E3062ANTMA1 PROFET High-Side Switch","metaDescription":"Infineon BTS409L1E3062ANTMA1 PROFET high-side power switch. 160 mOhm Rds(on), 1.8A output, 5-34V load.
