Drawing DO-41 mini,
and as marks is: one blue colored ring at left,
then 2 lines(one above the other):
on the first line only one digit: 4
on the second line only on letter B
the body is cylindric and black
----------

hi,
It was in the switching power supply of a cx3200 printer. This diode is short circuited, like the 2 transistors of the switching stage.
The cathode of the diode is connected to the collector of a NPN C4408 and the anode to the emitter.
No circuit diagram.
thank.
I agree with the 54 but
the package of 1N54XX is do-201ad or like. It to big.
The diode i am looking for is packaged in a do-41 mini or do-15.
I thinks it is a silicium 1NXX54 (5 for the green color, 4; and B for silicium).
However, i will try a FR202, a 2A fast recovery diode, wich mach the transistor in voltage, current and speed.
thanks
