CSD25402Q3A Description

Short technical summary and product information.

The CSD25402Q3A is a P-Channel NexFET power MOSFET from Texas Instruments, designed for power conversion and load management applications. It features a drain-source voltage rating of -20V and a gate-source voltage rating of -12V, with a single configuration. The device offers low on-resistance of 8.9mΩ (maximum) at VGS=4.5V and 15.9mΩ at VGS=2.5V, enabling efficient power handling.

 

This MOSFET is logic level compatible, with a typical gate threshold voltage of -0.9V, allowing direct drive from low-voltage logic circuits. It provides a continuous drain current of -72A (silicon limited at TC=25°C) and features ultra-low gate charge (QG typ 7.5nC, QGD typ 1.1nC, QGS typ 2.4nC), which reduces switching losses in high-frequency applications.

 

The device is housed in a SON 3.3mm x 3.3mm plastic package (VSONP DNH 8) with excellent thermal performance for its size, featuring low thermal resistance. It operates over a temperature range of -55°C to 150°C and is rated for catalog applications. The CSD25402Q3A is Pb and halogen free, and RoHS compliant, making it suitable for environmentally conscious designs.

 

Typical applications include power conversion circuits, load switches, and battery management systems where low conduction and switching losses are critical. The compact package and low thermal resistance support high-density PCB layouts.
