A 108 KB PDF covering the 2SC4890, categorised under schematics but in substance a single-component datasheet. The 2SC prefix belongs to JIS numbering and marks an NPN bipolar transistor; nothing further is stated in the name. The sheet should supply maximum ratings, electrical characteristics and the package outline. These help confirm lead assignment, check whether a shorted part was overstressed and choose an equivalent. The neighbouring 2SC4891 has a separate document, so verify the exact marking before using these values.
