CSD25302 and CSD16301 resistance while damaged

Rachel Coulter

Hello,

I'm looking for any information on specific failure data on CSD25302 and CSD16301. I would like to know if these MOSFETs could fail having a D-S resistance of around 5 to 10 ohms and able to conduct 3 to 7A continuously, while damaged. I know that there is some information about Reliability Data from the product folder but any further information would be greatly appreciated!

Any additional failure data on these two parts would also be greatly appeciated!

Regards,

Rachel

Rachel,

I am looking into this for you. Hopefully I will have something for you before Thanksgiving break (as in tomorrow).

Rachel,

Sorry for the delayed response. Things were a little hectic here leading up to Thanksgiving.

Talking to the team, here they aren't sure exactly what failure information you are looking for. If the FET is operating in the 5-10 ohm range, that means the FET is being driven very low, close to the threshold. Even at the minimum of 3 amps and 5 ohms, that is still 15W of power, far above the maximum power dissipation of the device. The FET will not be able to handle anything close to this. What type of failure information are you looking for exactly? Feel free to contact me directly and maybe I can be of more assistance. Thanks,

Brett
