Design a Custom BoardAbout This Component
N-channel power distribution switch in SOT-23-5 package rated for 1.0A continuous current. Features integrated protection including overcurrent limiting and thermal shutdown. Designed for load switching applications in portable electronics, with low on-resistance and fast transient response suitable for battery-powered systems.
Package: SOT-23-5 · 5 pins
Why does this need a breakout?
This 0.95 mm pitch SMD package is incompatible with breadboards and difficult to hand-solder. A breakout board brings the five pins to standard 0.1″ spacing, enabling rapid prototyping without reflow equipment. Essential for evaluating precision analog ICs like current-sense amplifiers in development circuits.
