Hi

I think the part is  FSD4488, unless I am looking at the wrong part of the circuit, what is the components circuit reference? RS do a FSD4480 which may be a suitable replacement.

Hi

I am confused, easily done! The FDS and PDH are different packages, 8 pin smd or TO-252. Either way RS usually have an equivalent.

You can download the manual from this link. You will probably have to sign up to download, it's free and no spam!

You probably won't find the device number but you should be able to find an equivalent, you just need to check the specs of any listed

Hi Bouncey

try this

Not sure where you get 7.9 amps from my data book says 44amps 20 volts logic level

thanks keith

one only one i can see is http://uk.rs-online.com/web/p/mosfet-transistors/5429670/?searchTerm=MOSFET+N-Channel+250V+7.9A+TO220FP&relevancy-data=636F3D3226696E3D4931384E44656661756C74266C753D656E266D6D3D6D61746368616C6C7061727469616C26706D3D5E5B5C772D5C2E2F252C5C735D2B2426706F3D3926736E3D592673743D4B4559574F52445F4D554C54495F414C5048415F4E554D45524943267573743D4D4F53464554204E2D4368616E6E656C203235305620372E394120544F32323046502673633D592677633D4E4F4E4526

its close but voltage states its 250v so not sure if this would be ok.

Here's the data sheet of a FDS4488, it's a 8 legged ic type http://doc.chipfind.ru/search.htm?s=FDS448&m=0&f=2 (http://doc.chipfind.ru/search.htm?s=FDS448&m=0&f=2). Might be the casing is different as already been mentioned.

I'd try an FDS4480
