Datasheet for the 2SC4480, stored as a 99.8 KB PDF that opens in any standard reader. By JIS convention the 2SC prefix denotes an NPN bipolar transistor; the name gives no maker, package or rating details. The document should present absolute maximum ratings, electrical characteristics and pin layout. Use it when replacing a damaged transistor or checking one in circuit, and compare any cross-reference carefully for voltage, current, dissipation and lead order against the PCB footprint.
