What transistor is this?

At least I think it’s a transistor. It is a burnt component on my espresso maker’s motherboard (one that they don’t make anymore).
If someone could identify it and tell me where to get one I would be extremely happy.

Can’t seem to find anything with the same coding on it. It’s very sad to have such a nice machine unable to do what it was created for.

Always seeing plenty of all brands used coffee machines in thrifty stores, peddler's malls, facebook marketplace... visit them, perhaps you get lucky if all else fails.

You do not need an exact replacement. If you can do some schematic tracing, you can always get a replacement.

There are 3 on the board the one that burnt has crumbled. Not to mention the smoke stain on the top of the machine.

I have gone and searched for schematics. No joy. Can I run tests on the good ones to find out their ratings ?

Similar labeling on the board. This is a bit of a Hail Mary. As I’ve said they don’t make this board anymore. It’s for controlling the solenoids attached to the steam and hot water boilers.

You won't get any schematic. Trace the schematic from the motherboard. Takes effort, but can be done. It will be quite a simple layout.

burning generally means power circuit. I have never seen a signal component fry. If it is a voltage Regulator/Rectifier.. you said there are 3 on the board? Well was it made in Japan? The Japanese have used diode packs for years on their motorcycles. They found a way to control the serial power direction and then pushed the power through a Regulator/Rectifier combo. To get it - would take you 3 years of "what the &@*$!??" If you have one that is good( heh heh) take it off, and take it to a shop...(just for kicks!)

Not sure what you mean by that statement?. All electronic components can fry/burn/smoke/explode/let the electrons fall out!. not necessarily in any order.
You probably mean that active components usually fail ‘open or short’?. Well, that happens to passives too.
The forum had a ‘mortuary’ for fried/dead devices started by @davenn which was always a laugh to read and see the pictures.
