Diode

Question

Any clues what diode this is, and value Many Thanks

it is not possible to say, but if you have saw waveform, like +-10V, connect to diode via 1k resistor, diode voltage to X input and ramp voltage on resistor to Y input of oscilloscope, and you will get VI curve. and by that you can tel if it normal diode, zener, or Schottky Fullscreen contentimage_176441.html Download Jive SBS Error
An general error occurred while processing your request. Note since you have single ground on your scope, you have to do math to get voltage on R1 resistor by subtracting diode voltage from resistor voltage. ir if you have TPS2024 you can do it directly like in picture

It's (99.9% likely) just 1N4148 which is a super-popular diode. (Fat yellow, then brown then yellow then gray stripes). Your replacement is likely to come with wire legs, and possibly uncolored except for one band which I think is to be positioned where the fat band is. If your current device works, that's easy to test with a multimeter.
