[QUOTE="PaulR, post: 614143, member: 176256"] Unfortunately, despite much looking around, I can't find the IRF3205VPbF anywhere on the RS site. Anyway, I've printed out the spec sheets for both of the MOSFETS and summarise them as follows: STW80NF55-08 TO-247 N-Channel 55 Volt 80 Amp 0.0065Ω (Typ) 0.008Ω (Max) Rdgs IRF3205VPbF TO-220 N-Channel 55 Volt 110 Amp 0.008Ω (Max) Rdgs I think that the very low Rdgs value is quite important, I found a IXTP110N055P which might do the job but it has a typical/maximum resistance of 11/13.5 mΩ. It dooes have the advantage that it can bought singly - I wouldn't have to buy a minimum quantity of 50! [/QUOTE]
