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 insight as to what may cause this or is there a facility where I can send a couple of these damaged FETs to get some failure analysis done? Thank you and please let me know what additional information you may need.
