Design a Custom BoardAbout This Component
Single-channel N-channel power distribution switch in SOT23-5 package. Rated for 5.5V maximum input with 1A load current capability. Integrates integrated circuit protection features including overcurrent and thermal shutdown. Commonly used for load switching, power sequencing, and battery management applications in portable electronics and industrial 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.
