A 53.4 KB PDF covering the 2SD2614 transistor, catalogued as a schematic although the name points to a single-part datasheet. JIS numbering places 2SD devices in the NPN low-frequency transistor group, commonly found in power stages, drivers and switching circuits. Use the document to read the pin assignment, absolute maximum ratings and hFE grading when diagnosing a shorted or open junction with a multimeter. Any substitute should match or exceed the voltage, current and dissipation limits listed, and the package must fit the footprint.
