Documentation for the 2SK2700, a part named under the Japanese JIS system where 2SK denotes an N-channel FET. The PDF runs to 389 KB, which suggests a fuller datasheet with characteristic curves alongside the absolute maximum ratings table. A technician tracing a dead power supply or inverter can use it to verify pin order and check whether measured values make sense. It is equally useful when selecting a replacement with equal or better ratings. Verify the printed code on the device first.
