Small 36.4 KB PDF for the 2SK1614, an N-channel field-effect transistor according to the Japanese 2SK designation. Beyond the part number the name reveals nothing, so manufacturer, package and ratings come from the document itself. Its compact size suggests a short datasheet. Use it to verify pinout before in-circuit diode-mode testing, and to compare maximum drain-source voltage and current against any proposed substitute, confirming the device marking on the board first.
