Help Identifying a Transistor

[jfd492]

i was wondering if i could get help identifying a transistor i have, its broken in half and i found no datasheets.

it has something like f54349 or fs343p printed on it. and actually im not really sure if its an f. Under that is an HO and a 36 and under that looks like a lowercase underlined i. it looks something like this:

f(5 or s)343p
HO 36
i

is there any way i can tell if it is pnp or npn?
how can i know which transistor to use when replacing this one?

now that i look at it more the first character looks like a 7

The F is for IRF series mosfets.

What whas this transistor in?

 

[jfd492]

It was in a blower resistor module
And i actually google it with the 7 instead of f and got alot more results, from what i reald its a mosfet rated at 75 amps and 55 volts.
So i guess the part number is 75343p and its going to be difficult to find a replacement

Glad you figured it out
You could replace it with a transistor with the exact or higher ratings.

 

[jfd492]

Thanks, so it doesnt matter which kind of tansistor it is as long as it is a mosfet with the same or higher ratings?

 

[ben7]

Same transistor as broken one, or replacement with same or higher current ratings.
Do you know if it is a PNP transistor or a NPN transistor or a P-channel or a N-channel mosfet?

 

[jfd492]

No, I have no idea
Is there a way to tell?

Datasheets from the internet. Basically, all common transistors have datasheets that you can check from the web.
