Four lead round IC controlling the fan motor in a hair drier. About 1/2 inch diameter black cylinder, 1/8 inch high. Markings are:
I'm thinking a bridge rectifier to drive the small DC fan motor.
Probably should just buy a new hair dryer, but I like to know how things work :-)

Assuming you meant "2W02M" rather than "2W202M", then your device is a
200V, 2A, silicon bridge rectifier:The "8650" could be a YYWW date code, and "G1" may in fact be "GI" (General Instruments).

Thanks, Frank. That looks like it. My eyes aren't as good as they used to be, even with a magnifying glass :-(
Strange they don't give the pinouts although it's easy enough to figure out.

I'm guessing it's it's similar to a WO2M. Doesn't hurt to put ina higher voltage rated part such as a WO4M. G1 is probably GI ( General Instruments ) so you could check but I think they've changed their name now.
8650 is merely a date code.Graham
I didn't know they did a 2A bridge in that style ! Could be useful.
