Hello. I am using your STP45N FETs in our power supply design for an audio amplifier and we are getting field returns with the STP45N65M5 part damaged. It appears that the gate and source have been shorted but I am not 100% sure. Do you have any insi...

Hi Pedro,I am following up to see if there is any indication in the data/observations I'd presented in this discussion that would indicate if the damage was due to an over-voltage at the gate or drain. Thank you. Regards,Alex

Hi Pedro,Yes I fully understand that the analysis needs to be done on my design thank you. The only information I am trying to gather from STMicro is if we can deduce whether or not the over-voltage condition occurred on the drain or gate. If this is...

Hi Pedro,OK so reversing the leads and the new results are below. This seems to make a bit more sense given that there is no short on the New Device. Is there anything you'd be able to tell me about the damaged devices? Assuming it was an over-voltag...

Hi Pedro,I am taking these measurements when the devices are not biased and are not under any load. I am simply touching the leads on a DMM to the device terminals when the part is resting on a table. Also the "undamaged" device is brand new, has not...

Hello. I took a DMM to an undamaged unit and logged the following readings:- VGD = Open- VGS = Open- VDS = ShortedI then took the same measurements on the damaged unit and these were the results:- VGD = 2.15Kohm- VGS = 2.15Kohm- VDS = ShortedPlease l...
