Frequently asked questions
Can I use CSD19505KTTT for high current applications?
Yes — the 200 A continuous drain rating at 25°C case temperature and 3.1 mOhm Rds(on) make it suitable for high-current switching in power distribution, DC-DC converters, and motor drives, provided the PCB thermal design can handle the 300 W dissipation limit.
