This is chopper power transistor in SMPS for Daewoo CN-200a or CN-200i
chassis.

Need a current sub or cross that works that is available from global.
The KSE/MJE13009 is not available anymore and the original maker of
these transistor said not intended for new designs (EOL).

NTE is not possible either and don't like them.

Cheers,

Wizard
