Good 3034 can be built for half that price -£2:25
if you buy say 10 genuine ones
Avoid any mosfet's from fleabay China component sellers
They are fakes and just melt under load
£2:25 will cover gen 3034, diode, 2 resistors
All you need is time - put a few together at same time
Decent wire n shrink wrap
Best basic 3034 is your own one if its genuine
Failing that firestorm £10 baby micro fet is worth a look
if peeps just need a good basic tiny fet
