Product Overview
The CJ2305 is a P-channel power MOSFET designed for low-voltage load switching and compact power-management applications. It features a 12V drain-source voltage rating, 4.1A continuous drain current, and low drain-source on-resistance down to 90mΩ at a 1.8V gate drive. Its low gate threshold voltage and modest gate charge make it suitable for efficient switching in battery-powered and portable electronic devices.
Packaged in a compact SOT-23 surface-mount package, the CJ2305 is well suited to high-side load switching, DC/DC converter circuits, battery management, and other low-voltage power-control designs where small size and low gate-drive voltage are important.
