At 466 KB, this PDF for the 2SC4325 sits under schematics, yet the name is a bare transistor part number, so expect a component datasheet. The 2SC designation in the JIS scheme indicates an NPN bipolar transistor, often marked on the body as C4325. Check the package outline against the part on the board before trusting the pinout, since lead order differs between packages, and compare voltage, current, dissipation and transition frequency figures when selecting a cross-reference replacement.
