Can anybody help me identify the specs of these mosfets?... the are on a stereo amp and i want to see if i can use them before i de-solder them

sorry for the crappy quality of the pics but the numbers on the front are:

K

 

D718A

 

O___OF

 

and the other one is:

 

K

 

B688A

 

O____OF

 

I am just wondering how i can get the specs for them.... thanks for anyhelp

Do you have manufactures details? (any name on the chip, quite possibly written in black on the grey background).

 

If not, these spec sheets might be a bit off but:

I dunno about the B688A though :s

the D (like C and A) prefix is only part of it, try adding 2S in front of it and have a look.

no promises, but in semiconductor nonmenclature it`s common to abreviate part numbers that way.

 

edited to add: that if you find the 2SD718 (the C suffix is just the pin orientation), you May find that other Semi is a Complimentary Pair to it.

I`ll have a look tomorrow for you when I have a bit more time.

meh, naff all on TV, so here you go dude:

and as I suspected, it`s compliment transistor IS the other number you mentioned.

good luck with your project

Thanks for the help adding the 2s in front of it pulled them right up... found out they are 8 amps and 120 volts... saddly not what i need
