Datasheet PDF of 45.2 KB for the 2SK3280, categorised here as a schematic. The 2SK prefix indicates an N-channel field-effect transistor according to JEITA naming. Use it to verify pin functions, maximum voltage and current, power dissipation and package outline when a switching transistor is suspected shorted or open. The file name gives no maker, package or revision details, so read those from the sheet and match them against the component actually fitted on the board.
