2n6122 tip41 A B or C?

[deathrow]

Hi,

The 2n6122 can be swapped out with tip41 but should this be a 41b or 41c? Do these have a minimum operating voltage or is this the amount they can handle as a max?

Just to add insult I accidentally bought 31c instead of 41 but these are 3a and not 6 so no good.?

Anyone?

Looks like you want the 31C's by Marco standards, so what you have right there seems to be the way to go?

Need 41 but thanks for the link.

I bought 31 by mistake thinking the same but the 41 and 31 are different amp rated. 41 is 6a and the 31 is 3a. I can’t see it being a good idea to use 3a if the board calls for 4a-6a??
The data sheet of 2n6122 is 4a continuous so I’m unsure of why Marco is selling 3a as replacement?

The A B and C are rating voltages for the upper end 40/60/100V etc.. I was wondering if they have a difference in the lower end operation?

The data sheets don’t give information on this? I’m probably being fussy and should just use C as most seem to?

A value is
Tip 41a 60v--6a--65w
Tip41b 80v--6a--65w
Tip41c. 100v--6a--65w

So if the voltage you have is 50v then the 41c is best

I would suggest if Marco are suggesting it would work, that it will be just fine... many of the components now are "uprated" comparative to their predecessors.

Vin suggests this in many of his bulletproofing posts.

RatShack doesn't always put the product listed on the package. Some of
the bridge rectifiers they sell are actually a higher rating than what
is on the printed packaging.

TIP31 is 40V
TIP31A is 60V
TIP31B is 80V and
TIP31C is 100V (sorry that was the one I was reading from when I said
100V)

I would personally think it is fine, but there are more knowledgable folk than I.

Awesome, thanks ?

As suggested on the other post, a lamp matrix row, even if it was incadescent, I cannot see that pulling more than 3A through that one TIP... 6A is a a HUGE draw through one row, I would be suprised if a pin even drew 6A through the mains? In fact VIN states a whole pin draws 2.4A - am I missing something here?

I can send you a couple of tip41c
foc if it helps you. Ken

Ordered some ?

The main reason for posting was just trying to find out if the lower end operation is affected by using c instead of a/b etc
I’m happy you’ve helped me with this and I’ve gone for 41c

Appreciate the offer though Ken
