BUK208-50Y and BUK213-50Y are single channel high-side TOPFET™ products produced by Philips Semiconductors. They have very low quiescent current, CMOS logic capability, Power TrenchMOS™, negative load clamping, overtemperature protection, overload protection, over and undervoltage protection, ESD protection for all pins, reverse battery protection, diagnostic status indication, low charge pump noise, operating voltage down to 5.5 V, loss of ground protection, and current limitation. They are suitable for 12 and 24V grounded loads, high inrush current loads, inductive loads, and relays and fuses replacements.
This document is a product data sheet for the Philips BUK212-50Y (SOT263B-01 package) and BUK217-50Y (SOT426/D2-PAK package). These are monolithic temperature and overload protected single high-side power switches based on TOPFET Trench technology. They are designed for 12 V and 24 V grounded loads, including inductive loads, and serve as replacements for relays and fuses.
