I need help identifying a transistor marked KS1212T to repair a power supply.
I have shorted the transistor. Please help me find a replacement part for it.

\$\begingroup\$ Are you sure the whole power supply is not fried? If you did not check it and fix the faults and other damage, putting in a new transistor will still blow up. \$\endgroup\$– JustmeCommented Jan 24 at 13:45

\$\begingroup\$ There was a short on the board, after removing this transistor short was gone, rest components seem's like ok. Will try to replace the transistor and take a look, if there is no result then the repair makes no sense to me due to non rational costs. \$\endgroup\$– Игорь НиконоровCommented Jan 25 at 8:09

It's a KS1212KA2T from Kwansemi Semiconductor.
Here is the datasheet for the 100V/36A NMOS.

\$\begingroup\$ I have replaced it IRF3710S with similar parameters but the power supply instead of rated 18v has an output of 17v, it holds the load but for some reason has a different voltage(( \$\endgroup\$ Commented Jan 26 at 9:09
