Are RFP50N06 And P55N06 the same?

[scotts530]

They both appear to have the same specs. Could the 50n06 be used as subs for 55nf06?

 

[Perry Babin]

That would probably be OK in most amps. What amp is it in?

 

[ppalli]

I agree, even if Total-gate-charge and Input-capacitance on RFP50N06 are double compared to P55N06
Since the clock of a sub-channel of a d-class is usually around 150-200 kHz, I also would say probably it can go, but it depends on the schematic

It's a Hifonics Zeus ZRX1500.1D

 

[Perry Babin]

I'd use the IRF3205 with 47 ohm gate resistors in that amp, assuming that it's like virtually all other modern Hifonics amps.

The driver transistors commonly fail and they often burn the ground trace on the PNP drivers.

The drain pad/traces for the PS FETs sometimes burn and it's difficult to see. Clean up the pads and examine them carefully.
