In the given diagram the near IC IR2148 MOSFET is IRFP4321 and the bias resistor is 6 OHM . If i replace these two MOSFET with IRFP460 , what should be the resistor value ? can someone give me the answer ?


 

If the IRFP460 (Ciss=4200pF) has half the input capacitance of an IRFP4321 (whose dataSheet I can't find), you could double the gate resistor for each of the two IRF460 MOSFETs.
