Single-channel high-side switch with 16 mOhm Rds(on) and 8 A rating
The Infineon BTS5016-1EKB is a single-channel PROFET high-side power switch in a PG-DSO-14-30 package. It switches loads up to 8 A from a 5 V to 28 V supply rail, with a typical on-resistance of 16 mOhm — the conduction loss at 8 A is about 1 W, so the SOIC-14 footprint needs a copper pour on the drain tab to keep the junction below the 150°C maximum.
Built-in fault protections eliminate external supervision
The BTS5016-1EKB integrates current limiting (fixed), open-load detection, over-temperature shutdown, over-voltage clamp, and short-circuit protection. For a 24 V industrial solenoid or an automotive lamp load, these protections mean no separate current-sense resistor or comparator is needed — the switch handles fault detection internally and latches off or cycles as the fault condition dictates.
The 150°C junction temperature rating places this part firmly in the automotive and industrial temperature range. It suits engine-bay electronics, transmission control modules, and outdoor industrial I/O where ambient temperatures regularly exceed 85°C. The PG-DSO-14-30 package with exposed pad helps conduct heat to the PCB ground plane.
