Its 12mOhm typical Rds(on) keeps conduction loss under 1.2W at 10A continuous output, which means the exposed-pad package can dissipate that heat without a dedicated heatsink in still air — a real advantage on densely populated automotive PCBs. ## Load supply range and fault coverage The switch operates with a load supply from 5V to 28V, covering 12V and 24V nominal rails plus 5V logic loads. Compared to the low-side HITFET BTS142DATMA1 (23mOhm, 4.6A), the BTS50121EKBXUMA1 offers roughly half the on-resistance and more than double the current capability, but is a high-side configuration — the two are not pin-compatible, so the topology decision comes first. ## Active production — no obsolescence clock It is in current manufacturing with no announced end-of-life. The PG-DSO-14-47-EP exposed-pad package is a standard Infineon footprint, widely second-sourced in form factor if not in exact Rds(on). ## Temperature grade and board integration Rated for junction temperatures from -40°C to 150°C, this switch is qualified for under-hood automotive environments.","metaTitle":"BTS50121EKBXUMA1 Infineon PROFET High-Side Switch 12mOhm 10A","metaDescription":"Infineon BTS50121EKBXUMA1 PROFET high-side power switch, 12mOhm Rds(on), 10A max, 5-28V load, -40 to 150°C, active production.
