Anyone know of an alternative, or maybe even has this part please?
APM3055L N-channel field effect MOSFET
Its for an ATi Radeon 9200SE video card i picked up for £5 but dropped it damaging this MOSFET! (Or it was already damaged and thats why i got it for a fiver!)
Please help?!?
Cheers

 

Hi Salviablue,

There are a lot of possible candidates to replace this transistor, and
which one is it, the TO-252 or the SOT-223 ?
Here's a link to the datasheet:

http://www.alldatasheet.com/view.jsp...hword=APM3055L

The selection will depend on what you can get at your local candy store.

Thanks for the reply.
Its the TO-252 (DPAK) But i could use either
I have already got the datasheet for this but i am not entirely sure as to which lines in the data are the critical readings to match with another MOSFET?

Plus I am not entirely sure as how to go about looking up a viable replacement? Should i just google for n channel MOSFETs, hunt the datasheets, then compare the values? Then find out which ones are actually available to purchase NOT in thousands but just a few (W/no min order!)?

I am not entirely `up` on the critical values and influencers of these MOSFETs

Cheers!

 

dosent matter all kind of n-channel enhancement mode mosfets possible. Only diffrent companies have different types and diffrent current and voltage scale. I found this types for you

and also you can find a lot of n-channel deployment mosfet via google.. bye

 

Hi,

I'd do a bit 'o' research like the guys suggested, but as you pointed out, availability can be a problem. Rapidonline.com has plenty of components, cheap, as does farnell.com and rswww.com.......the last two have minimum orders though. It's all very well finding a 'perfect' match, but if you cant get hold of the bugger then its not much use. At a guess I'd say any N-channel MOSFET, with *similar* specs would do...it is a graphics card after all, not a high powered inverter, check if it has inbuilt diodes though, some do, some don't...I'm not really up on MOSFETs.

Gah, I need a decent graphics card...wonder where I could get hold of some decent comp parts cheap...repairing them would be a challenge (yes, I'm sad).

Good luck,

Blueteeth.

Thankyou very much to everyone that replied.
I have just picked up an old 32MB graphics card for a few quid of the market because it has a MOSFET with the same numbers in `3055`. I busequently looked up its data and it is an N channel, field effect MOSFET (PHD3055L) which i am going top use. Just one thing though, how do I get it off the board with out damaging the MOSFET? I tried desoldering, the legs come off no probs but i cant get the body off as it is fully soldered on. I dont want to apply too much heat so as to damage the component?

 

You have to apply enough heat to unsolder it's heatsink tab from the board - however, silicon semiconductors can take a considerable amount of heat!.
