Named for the 2SC3225, this 212 KB PDF is filed as a schematic but is expected to be the datasheet for this NPN part, 2SC being the JIS prefix for NPN transistors. The name lists only the part number, so consult the pages for case style and electrical figures. It serves to confirm pinout before testing, read voltage, current and power limits, and verify that any substitute meets the original specification.
