Datasheet covering the 2N3055, the classic NPN power transistor in a TO-3 metal case, provided as a 171 KB PDF. Expect collector current and power dissipation ratings, safe operating area curves, gain versus current and the case outline showing base and emitter pins with the case as collector. It is useful for repairing linear power supplies and audio amplifiers, checking heat sinking, testing junctions and choosing replacements or complementary PNP parts such as the MJ2955. Verify the manufacturer marking, since ratings vary slightly between makers.
