triac Identification.
Benjamin Richards
I am trying to source some information on a triac that has come out of my
gas heater.
The dead beastie is a TLC221T. I have done a search through the web and the
likely retailers and nothing shows. Does any body have any specs on this
device so as i can obtain a suitable replacement.
Thanks in advance.

the 8 and 10 amp ones from DSE.

I think it is an ST or SGS Brand.
Does it look like a TO-220 packge with the top tab cut off?
I think Philips have something similar but in a TO-220 package BT13.....
brand.

I believe i have the info that i require to source a suitable replacement.
if not i'll be right back.
I initally tried a TRIAC that i had in my spare bits bucket (SC141D) and it
didn't work (yes it tested it prior to installing it) so i was kinda worried
that it was something really exotic. The service agent don't work W/E so i'm
going to give them a call tomorrow to see if they carry the part. I'll
probably have to buy a whole board from them. (ouch!)
Anaging thanks to all that replied

** Yes , the number looks wrong to me to. If only people would realise
that the part number alone is NOT enough to get data on a device. One needs
the brand name, (or logo description) package type, some idea of the age and
the application.
These are all known to the OP but for some god knows what reason most
elect to keep them secret.

** You have me "bang to rights" there Ross.
I am 100% guilty of assuming the OP was not blind.
Please see my other post here for a big whinge about posters giving
only the damn part number and no description of the device. Of course that
must now be ammended to exclude blind persons. Shame shame.

** Just in case there is any misunderatanding here Ross, the reasons for
wanting a device description are no small matter.
1. The brand name along with the application and device age tells me what
maker's data book to pull out and which edition.
2. The package and device function tells me what section to look in.
3. The part number with all prefixes and suffixes gets me down to the
actual page and raw data.
4. Using that data and knowing the application a possible substitute can
be suggested.
If some DH gives only a part number and then has one letter or digit
wrong he deserves no consideration at all in my book.
Unless, of course he/she is blind.
Funny thing, I haven't ever met a blind electronics tech.

Yes the Prefix is correct it is a TLC221T. i must appoligise about not
posting the package type with my original post. Having said that, There is
NO need to flame me. As for the Prefix ... give me some credit.

** Oh come on, nobody flamed you!
BTW You have still not posted the package type.
Can you see a post from "Marc" with all the data? You made no response
to it so maybe your ISP had not got it.
The nearest to that data is the Z0405DF in the Farnell catalogue as
706-085 for $2.60 + gst.
The type is a special sensitive gate one meant to operate from a logic
cct. (a uP maybe)

** Marc gave the figure of 1 amp rms for this, I(TRMS).

** The triac the OP was interested in is one darn obscure device in a
strange package. It appears to be obsolete and all traces of its existance
removed from the web. It has become a "non triac" if you follow my drift ;-)

*******Removed from the web perhaps but not from a trusty old DATA book.:-
TRIAC TLC221T MAX.REP.OFF STATE VOLTAGE, 400 VDRM.MAX RMS CURRENT, 1.0
AMP. MAX.MAX.GATE FIRING CHAR. 1st QUADRANT ,5mA @VGT 3.0VOLTS.
OUTLINE DRAWING ,MU166.
Nothing magic about this device!!!!

OK, Marc gave similar data. But what does the package look like?

Sorry, I seem to be having problems with my ISP. I posted two messages
last Monday, one to aus.electronics, another to comp.dcom.modems, but
neither has surfaced in my news feed. I also can't find them in the
Google archives.

describe the outline drawing MU166 then we might be a little
more informed about it.
*******Imagine a TO220 package with the heatsink removed,that's about the
size of a TLC2215.Leadout is (L-R) ,M1,M2,G.
Nothing magic about this,bog standard!!
