Help Identifying Component

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:

+
G1
2W202M
8650

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.

I didn't know they did a 2A bridge in that style ! Could be useful.
