CSD18511Q5A Description

Short technical summary and product information.

The CSD18511Q5A is a 40V N-channel NexFET power MOSFET from Texas Instruments, designed to minimize losses in power conversion applications. It features a low typical on-resistance of 1.9mΩ at VGS=10V and 2.7mΩ at VGS=4.5V, with maximum values of 2.3mΩ and 3.5mΩ respectively. The device supports continuous drain current up to 159A (silicon limited) and 100A (package limited) at TC=25°C, with a pulsed drain current rating of 400A.

 

This MOSFET is logic level capable, with a typical gate threshold voltage of 1.8V and a maximum of 2.45V. It offers low total gate charge of 63nC at VGS=10V, contributing to efficient switching. The device is avalanche rated with a maximum avalanche energy of 157mJ, and has low thermal resistance with a junction-to-case thermal resistance of 1.2°C/W.

 

The CSD18511Q5A is housed in a SON 5mm x 6mm plastic package (8-PowerTDFN / 8-VSONP) and is surface mountable. It is RoHS compliant, halogen free, and has lead-free terminal plating. The operating junction temperature range is -55°C to 150°C.

 

Typical applications include DC-DC conversion, secondary side synchronous rectification, and battery motor control.
