PDF of 362 KB named for the 2SK211. Under the JIS system the 2SK prefix denotes an N-channel field-effect transistor, which suggests a manufacturer datasheet even though it is labelled a schematic. The name gives no package or grade information. A technician uses such a sheet to confirm gate, drain and source positions, check absolute maximum ratings and compare characteristics with possible replacements; inspect the marking on the original part, since grade suffixes affect key parameters.
