Using IRFP460LC instead of IRFP460 in halfbrigde SSTC running of rectified mains
Phil33ts, Sun Jan 10 2016, 12:13PMHey
I've bought some cheap IRFP460LC.
My question is are they a direct replacement to IRFP460?
Datasheet says:
wrote ...
• Ultra Low Gate Charge
• Reduced Gate Drive Requirement
• Enhanced 30 V VGS Rating
• Reduced Ciss, Coss, Crss
I want to use them in my halfbridge SSTC that runs on rectified mains 230V AC.• Ultra Low Gate Charge
• Reduced Gate Drive Requirement
• Enhanced 30 V VGS Rating
• Reduced Ciss, Coss, Crss
Will I have to change gate drive resistor (10 ohm atm) for this new transistor?
Thanks in advance!

It should work fine. You shouldn't have to change the gate resistance, as reduced Ciss. The RdsON is still higher than what I recommend, at nearly a third of an ohm, but people use the 460s successfully, it's just not my cup of tea dealing with that much heat.
