Overview
The CSD18511Q5AT is a 40 V N-Channel NexFET™ power MOSFET produced by Texas Instruments. This device is designed in a compact SON 5 × 6 mm package, making it ideal for applications where space is limited. The MOSFET is engineered to minimize losses in power conversion applications, offering low RDS(ON) and low thermal resistance. It is suitable for a wide range of operating temperatures, from -55°C to 150°C, and is RoHS compliant, Pb-free, and halogen-free.
