With only that to go on, you might stand a better chance by getting hold of a schematic for what its out of.Help please.
Diode, black cylindrical body, white/gray/silver stripe on the cathode end. On the body: J-4. What model or can someone link datasheet for it, please.
Hm, I did not think it would be this complex.With only that to go on, you might stand a better chance by getting hold of a schematic for what its out of.
Assuming its not blown, a Vf reading from a DMM diode check function will tell you a fair bit - if it is blown, look for another just like it and measure that.
Doesn't sound like its anything fancy speed wise, but the current would be too much for a 1N400x series, as long as you're sure its used as a half wave rectifier, you could try a 1N5408.Hm, I did not think it would be this complex.
Ok. Here is the rest of the story.
it comes from a General Electric Can Opener, Catalog Number D2EC60, Maximum 1.3 A, 120 volts AC, 50-60 Hz. The electric motor works. But the schematic is really simple, two prong wall plug, one wire from the "left" prong goes to the electric motor (red), another wire comes out of the motor (yellow) and goes to one side of the ON/Off witch, from the other side of the ON/OFF switch I have this diode and diode goes to the "right" prong.
Left Prong->motor->switch->diode->Right Prong
As you can see once I plug the two prong plug into the wall, the circuit is complete.
The best I can figure out the diode forms half wave rectifier.
AC devices don't usually have a silver band at one end.Are you sure it's not a thermal fuse/varistor?
Many portable appliances have these and they look just like diodes.
