The attached circuit uses 12 RFP40N10 Harris TO220 parts (3 per bank). I have tried using IRF3710z but they repeatedly fail under load stress, almost immediately. Total rail voltage is 80v. Base switching frequency is around 80khz.
Is the IRF3710z not a good substitute in this circuit?
Is it being driven improperly in this circuit?
Is there a drop in replacement Infineon offers for the RFP40N10 ? Perhaps a more modern MOSFET with better specifications that won't require modification of the circuit?
Thank you.
Matt
