PDF reference sheet for the 2SD1682 transistor, 150 KB, stored in the schematic category. The name gives only the part number, which follows the Japanese JIS convention where 2SD identifies an NPN bipolar device for low-frequency or power work. Repair use is practical: confirming the pinout, which differs between packages, and checking breakdown voltage, collector current and dissipation when sourcing a substitute. Read the body marking carefully, since manufacturers often drop the 2S prefix and print only D1682.
