    Please help ID this component. I want to find the Datasheet. I did a google search of
    e3 Z3m y725

    but nothing can up... this is from a dishwasher control the one next to it has a chip blown off of it....

    Hey Welcome

    It could be a 3.3V reg from ST semiconductors.

    Thanks R!@@,
    would you be so kind and explain to me how you read this Reg.

    symbol must be the logo for ST Semiconductors.
    e3 =?3v
    z3m =
    y725=?

    I can see the ST logo and looking at the numbering it's just an assumption. I have to see how the component is connected to clarify

    Exactly,

    Even you can trace the Input Supply to this Chip and the Also by tracing the output of this chip to other devices whether it is connected with Supply Pin if yes then you can check the range of the supply and as this is 3 Pin device and i think it must be some regular chip.

    Can you be sure that the nearby damaged device is actually identical? For instance, if the devices are in fact voltage regulators, would they necessarily be for the same voltage?

    Here is a photo of the Board sorry about the quality of the photo

    This Chip is connected with the transistors so now i think its not regulator chip let me think on this. Trying to get the rid of this device.

    you can see most of the component ID on the left.. and 4 more on the board .. I was thinking it is a switching component?

    Is that a card..if so I see an open collector driver config.
    You got to show us more of the device. Where the blown chip is connected to?

    it is a Dishwasher control the blown chip is connected to the diverter valve. a motor that controls the water flow to the upper and lower spray arms...

    then it could be mosfet or a transistor

    remove a working one, u seem to have plenty and check it to see if it a FET or a Bipolar.
    after that you have to see the load specs. But this is the easy part.

    U need to find the drive voltage level to be sure if it is Voltage driven or current driven , that is the blown chip..

    Mosfet uses voltage to switch and gate drive voltage is higher than a bipolar base drive. A transistor base will always have a 0.6V limit when saturated. This can also tell you what type of component is there.
