    Can a to 247 be wired to use one diode if the part has dual diodes If so how would it be wired, orig part is 30a 600v diode 2 pins only 3rd pin is cut very close to case only has single diode. What I found is a t0 247 that has dual diodes 30x2 other part I have is U1660 single diode to220 case says 15a and peak is 30a would that work. application power inverter

    Yes you can. Note the diode arrangement under the photo in PDF:

    Orig part is a smt sot 23 transistor bjt pnp the drive circuit is for pulling fet banks to zero. Im wondering if 150v 0.6a would work? I looked at the pdf it shows pins 1 and 2 or 2-3 to use just one of the diodes do I have this correct. http://www.datasheetcatalog.com/datasheets_pdf/A/P/T/3/APT30D60BHB.shtml On this part pins 1 and 2 to use only 1 of the 2 diodes in circuit is this correct?

    Use the proper pins for the product you are using. They may all be configured differently.

    The output stage diode is the second question about wiring a dual common mode diode just using one diode Is it done by running pin 1 and pin2 to board and leave out pin3 I would use both diode in the one to247 part but I heard they dont share current well. thank you for previous replys

    They share current fine.

    It's a normal mode of operation and many commercial switching PSUs parallel the dual diodes in flatpack schottky diodes.
