BUK212-50Y and BUK217-50Y are single channel high-side power switches based on TOPFET™ Trench technology, with temperature and overload protection. They are suitable for applications such as 12V and 24V grounded loads, high inrush current loads, inductive loads, etc., and can replace relays and fuses.
The document describes the BUK212-50Y and BUK217-50Y, which are monolithic temperature and overload protected single high-side power switches based on TOPFET Trench technology. These devices are available in SOT263B-01 or SOT426 (D 2-PAK) packages.
