CSD18540Q5B: How many Continuous Drain Current@ VGS=10V, TA=70°C

Eddie,

Thank you for your interest in our MOSFETs.

We have a document here https://www.ti.com/lit/an/slvafg3/slvafg3.pdf?ts=1665754099686&ref_url=https%253A%252F%252Fwww.ti.com%252Fsitesearch%252Fen-us%252Fdocs%252Funiversalsearch.tsp%253FlangPref%253Den-US%2526searchTerm%253Dslvafg3%2526nr%253D1

This document details all our MOSFET technical content on the web, in this document in section 1 is a series of articles on Understanding MOSFET datasheet specifications which explains how current ratings in a datasheet are calculated.

Following these calculations the CSD18540Q5B has a calculated  current rating at 70degC of ~26A, down from the datasheet rating of 29A at 25degC.

Thanks

Chris
