Data East FET transistor question
jim_b
Whoever had the game before me replaced the fuse with an 8 amp instead
of a 3 amp. I've replaced the fuse and coil. It now will blow the fuse
in about 10 seconds, the coil stays activated as soon as the machine
is turned on, until the fuse blows. I'm assuming the FET transistor
(Q1) is the problem, it appeared overheated.
The part number on this transistor is ST3635. I can't cross reference
it anywhere that I've found online so far. Marvins pages on the
earlier Data East games show this to be a TIP36c. He also says that
the equivalent is NTE393. Since my machine is a 1997 manufacture and
his online repair guide goes to 1995, is this a correct part number?
Also, Radio Shack makes a FET that I put in this machine earlier to
get a turbo bumper working. When I bought the machine, that particular
transistor was missing. It now works fine. Any guesses if this FET
from Radio Shack may work in this machine for the kick up trough?
If not, where do I find the power transister?
Plus, does anyone else have any ideas they may want to share about
this type of problem? Could it not be the power transistor?
Thanks,
Jim B.

My JP also uses the TIP36c / NTE393. This is likely your problem. But, my
unit is from 1993. BUT, I have a question, is this the original transistor?
Try looking at one of the other coil drive transistors. These circuits are
mirror image. See if you can get a number off one of them. It is possible
someone has replaced your transistor with an improper one and thats why the
cicuit is failing..
This is the data sheet for the Tip36c:

I think this is the cross on the ST3635:
http://www.nteinc.com/specs/200to299/NTE222.html
These are 2 very different items. Also, be careful when buying items from
the Rad Shack. They are times when the transistors are not direct
replacement(pin for pin) and can cost you.
Maybe one of the other group members can tell you where to get the tip36c. I
searched Jameco's site and they no longer list it ... weird.

Here's one place to get TIP36C's --

accordint to the game manual. The person at the electronics store gave
me incorrect information regarding the part number. It's actually
STP20N10L. There is a match on NTE, it's number is NTE2987. The
ratings on this MOSFET are virtually identical to the Radio Shack
number, IFR510. I'm not saying this is a perfect replacement part, but
it sure appears close.
I will see if it works as a replacement in this case. If not, I'll
chalk it up to stupidity on my part.

ST discontinued the 20N10L a few years ago and replaced it with the 22NE10L.
The newer part is available but nearly impossible to find.
Unfortunately, NTE does a lousy job of cross referencing transistors.
Just thought I'd warn you -- the IRF510 is close, but not close enough. You
have a chance that it will not work work due to biasing differences and you
may also be too low for the current rating. First, the current rating isn't
nearly high enough. You would need something closer to the 540 instead of
the 510. Second, the IRF series isn't a logic level driven MOSFET. You
*must* use an IRL series. The best fit for the 20N10L is the IRL540. These
typically sell in the $2 to $3 range but are a little harder to find.

Wasnt that Sega?
Should be a P20n10L....
Star Wars Trilogy, right? I dont always get the shortened names right....

We have lots of the 20n10l's and are now starting to get the replacements.

Thanks for the info. We have a good electronics surplus house in
Orlando known as "Skycraft" that gets parts from NASA and other
sources that were sold for scrap. They have a lot of parts but I'll
steer clear of them due to what you told me. I did find a local
pinball repair house just yesterday at the auction. They have the
correct part number. I admit to not being a rocket scientist on
electronics. However, I do learn quickly :-)
I have to wait until Tuesday to get the correct part that you told me
about in the prior post, but I definitely want my machine to work
correctly.
Thanks again!!

Yes, Star Wars Trilogy.
Sega, Data East..........same thing :-)
Yes the part number you listed is the same one that I found out about
later. Will be getting the right part on Tuesday.
Thanks!

I was cross referencing the number he gave to show him it didnt make sense
