    Help identifying rectifier type

    I have this TO-220 rectifier: Photron PSR16C40CT but i'm not sure what type is it, Fast Recovery? Schottky? also i would like to know how many amps it can take.

    Could you post a photo, and perhaps tell us where you got it? I do not recognize the number, so it could be a cheap Chinese rectifier made specifically for a particular device and not intended to be replaced or used elsewhere.

        It was scavenged from the secondary of a very very old AT psu, the PSU is in the trash long ago.

        Measured with tester in diode mode reads 122, 123.

          Photron seems to specialize in making Schottky dies/wafers... a tiny semi manufacturer in Taiwan.
          What I found, using the root part number it's a dual-diode (8A each, 16A total) common cathode. It's probably Schottky but a Mospec close part # is a 600V fast-recovery. All other makes are 40V Schottky.

          You should be able to tell if it's a 600V or a 40V application. Hope this helps.
