CSD17551Q3A Description

Short technical summary and product information.

The CSD17551Q3A is a 30V N-Channel NexFET power MOSFET from Texas Instruments designed for low-loss power conversion. Key specifications include a maximum drain-source voltage of 30V, continuous drain current of 48A at 25°C case temperature, and a low on-resistance of 9mΩ at VGS=10V. The device features logic-level gate drive with a typical gate threshold of 1.6V and low gate charge (6nC typical at 10V) for efficient switching. It is housed in a compact 8-PowerVDFN (SON 3.3mm x 3.3mm) surface-mount package, offering low thermal resistance and avalanche rating. Applications include DC/DC converters, load switches, and power management in computing and industrial systems.
