BUK205-50Y is an overload protected power switch based on MOSFET technology, featuring vertical power DMOS switch, low on-state resistance, and 5V logic compatible input. It is suitable for general controllers to drive lamps, motors, solenoids, heaters, etc.
The document describes the BUK205-50Y, an SMD version of the BUK201-50Y. It is a 5-pin plastic surface mount device configured as a single high side switch with vertical power DMOS technology.
Key features include low on-state resistance, overtemperature protection that self-resets with hysteresis, and overload protection against short circuit loads via output current limiting. The device also offers high supply voltage load protection, status indication for overload conditions, very low quiescent current, and ESD protection on all pins.
