CSD18512Q5B Description

Short technical summary and product information.

The CSD18512Q5B is a 40V N-channel NexFET power MOSFET from Texas Instruments, designed for high-efficiency power conversion. It features a low on-resistance of 1.6mΩ (max) at VGS=10V and 2.3mΩ at VGS=4.5V, enabling minimal conduction losses. The device supports a continuous drain current of 211A (silicon limited at TC=25°C) and a pulsed drain current of 400A.

 

This MOSFET is logic level compatible with a typical threshold voltage of 1.6V, allowing direct drive from low-voltage controllers. It offers low gate charge (Qg typ 75nC) and low gate-to-drain charge (Qgd typ 13.3nC) for fast switching. The device is avalanche rated and has low thermal resistance.

 

The CSD18512Q5B is housed in a SON 5mm x 6mm plastic package (8-VSON-CLIP) with Pb-free terminal plating. It is RoHS compliant and halogen-free. The operating junction temperature range is -55°C to 150°C.
