The exposed-pad PG-DSO-14-47-EP package sinks heat into a board copper plane. ## Load voltage range and fault coverage The load supply accepts 5 V to 28 V. The part integrates open-load detect, over-temperature shutdown, and over-voltage clamping. ## Temperature grade and package — where this switch lives Junction temperature rating spans -40°C to 150°C, which qualifies it for underhood automotive and industrial cabinet environments. For a new design, this part is a safe selection without a mandatory obsolescence review. ## How it compares to the BTS142DATMA1 The closest functional sibling in the Infineon portfolio is the BTS142DATMA1, a HITFET® low-side switch with a typical Rds(on) of 23 mOhm. The BTS50081 is a high-side switch with an 8 mOhm Rds(on) — roughly one-third the on-resistance — and a lower maximum load voltage (28 V vs. 42 V). If your design requires high-side switching (load between switch and ground) and you need the lowest conduction loss, the BTS50081 is the better fit. If you need low-side switching (load between supply and switch) or a higher voltage rail, the BTS142DATMA1 is the alternative.","metaTitle":"BTS50081EKBXUMA1 – Infineon PROFET® 8 mOhm High-Side Switch","metaDescription":"Infineon BTS50081EKBXUMA1 PROFET® high-side power switch: 8 mOhm Rds(on), 11A max, 5-28V load, -40 to 150°C.
