The cap is marked \"ITALY 8123, 2N3055E\" with a manufacturer logo, and the date code 8123 indicates 1981. The leads are straight and unused. The case and flange show light storage marks and minor discoloration, as pictured.\u003cbr\u003eThe 2N3055 is one of the most widely used NPN power transistors, found in linear power supplies, series-pass regulators, audio power amplifiers, motor drivers and other general-purpose power switching and amplification circuits. It is rated 60 V VCEO, 15 A and 115 W, and the TO-3 case is the collector, so it bolts directly to a heatsink. Use an insulating kit when the heatsink is not at collector potential.\u003cbr\u003e\u003cbr\u003eFeatures:\u003cbr\u003eNPN silicon, 15 A collector current\u003cbr\u003e60 V VCEO \/ 100 V VCBO\u003cbr\u003e115 W power dissipation at Tc ≤ 25°C\u003cbr\u003e2.5 MHz transition frequency\u003cbr\u003eTO-3 metal case, collector tied to case\u003cbr\u003eVintage 1981 production, made in Italy\u003cbr\u003e\u003cbr\u003eCompatibility:\u003cbr\u003eReplacement for the 2N3055 in power supplies, regulators and audio amplifiers. The NTE equivalent is the NTE130. The ratings listed are the standard 2N3055 family ratings. The \"E\" suffix is a manufacturer variant marking, so check gain and safe operating area against your circuit for matched-pair or critical amplifier use. The complementary PNP is the MJ2955.\u003cbr\u003e\u003cbr\u003eQ\u0026amp;A\u003cbr\u003eQ: What is the pinout?\u003cbr\u003eA: TO-3. The two pins are base and emitter, and the metal case is the collector.\u003cbr\u003eQ: What replaces the 2N3055?\u003cbr\u003eA: Common equivalents include the NTE130 and other 2N3055 versions rated 60 V \/ 15 A \/ 115 W.\u003cbr\u003eQ: What is the PNP complement?\u003cbr\u003eA: The MJ2955.\u003cbr\u003eQ: Does the case need to be insulated?\u003cbr\u003eA: Yes, if the heatsink is not at collector voltage. The case is the collector, so use a mica or silicone insulator and shoulder washers.\u003cbr\u003eQ: Who made this transistor?\u003cbr\u003eA: It is marked \"ITALY\" with a manufacturer logo. We list it as unbranded because we have not verified the maker.\u003cbr\u003e\u003cbr\u003eDISCLAIMER\u003cbr\u003eItem is new old stock, sold as pictured. Not tested.
