Short PDF of 30.9 KB for the 2SK2538, with the part number written in lowercase in the original name. The 2SK prefix follows the JIS convention for N-channel FETs; no other device details are given. A small file like this is typically a brief datasheet with pinout and key electrical limits. Use it to identify leads before testing with a multimeter in diode mode and to confirm voltage and current ratings when selecting a substitute for a failed transistor.
