I've been looking for the proper resources in order to find out what component this is.

The manufacturer wouldn't provide any schematics or technical information.

The inscriptions on it are : KE with an X printed sideways.

enter image description here

Unfortunately, this device (whatever it is) is shorted on one side.

    \$\begingroup\$ Where did the chip come from? It could be helpful if you add a photo of the circuit it was removed from. \$\endgroup\$ Jun 14, 2018 at 16:17

We don't actually accept or reject users, but we do up or down vote posts. Only time will tell how your question was received according to the votes. \$\endgroup\$ Jun 14, 2018 at 17:02

    \$\begingroup\$ "The manufacturer wouldn't provide ANY scematics nor technical info's." What manufacturer? Manufacturer of what? If you know the manufacturer of this part, then you should tell us. \$\endgroup\$ Jun 14, 2018 at 17:03

    \$\begingroup\$ "with an X printed sideways". I don't see any "X" either. Also a "X" printed sideways (rotated 90 deg?) would still look like a X, so how could you tell if it was "sideways"? \$\endgroup\$ Jun 14, 2018 at 18:24

Probably a 2SK3065 60V/2A n-channel MOSFET. SC-62 is another name for SOT-89.

That looks to be a SOT-89 package. Most likely it is some kind of transistor or linear regulator.

This is a unlikely package for a diode. I've seen diodes in SOT-23 packages, but by the time they need to dissipate more power they usually come in SMA packages.

Probe around with a ohmmeter, and maybe you can figure out what kind of transistor this is and which pins are what leads.

    \$\begingroup\$ It could be a voltage regulator as well. \$\endgroup\$ Jun 14, 2018 at 17:49

  • \$\begingroup\$ Unfortunately, this device is shorted on one side. Probing just showed up to be a transistorbetween left and center pin, the right one is shorted with the center one \$\endgroup\$ Jun 15, 2018 at 15:11
