For very high quality audio my suggestions will come from D Self's book on transistor power amps. The 2N3055 NPN silicon power transistor is designed for general purpose switching and amplifier applications. Tell us what your application is and we can suggest modern devices. Thus, an assembly in which the transistor will work at the limit, the metallic type is also as indicated. However, the 2N3055 is over 50 years old! There are far better power devices around now which have vastly higher voltage and dissipation ratings, much improved 'secondary area breakdown' ratings and are MUCH more linear for gain V collector current.īTW the emitter is almost never connected directly to 'ground' usually a 1 Ohm, often much less, resistor in circuit to effect DC stability. The electrical characteristics of the two transistors, TIP3055 and 2N3055 are the same, however, by its casing, the metal 2N3055 has a slightly greater ability to dissipate heat. 2N3055 Features DC Current Gain hFE 2070 IC 4 Adc CollectorEmitter Saturation Voltage VCE (sat) 1. The pin configuration of 2N3055 is given below. There are now easier to use washers made of a silicone plastic that do not need the paste. Like any other transistor 2N3055 has three pins namely EMITTER, BASE and COLLECTOR.
FOR SALE 2N3055 and MJ2955 power transistor complimentary pair.
2N 3055 TRANSISTOR PC
You also need some heat sink mounting paste, that white snot you use with PC CPUs. 2N3055 AND MJ2955 Power Transistor pair TO-3 NPN & PNP MOSPEC Genuine Transistor - 5.99. The 2N3055 and many other power transistors were always used with these. Shipping costs are automatically calculated during checkout according to the chart below. Orders are typically processed the same or next business day. You are missing jecci a "mica washer mounting kit". The 2N3055 Transistor has a power dissipation of 115W. 2N3055 Silicon NPN Power Transistor Audi o Power Amp, Medium Speed Switch TO3 Type Package Description: The 2N3055 is a silicon NPN transistor in a TO3 ty pe. Can someone give me a typical application for this 2n3055 transistor, showing how it is typically used in a circuit? What am I missing? The MJ2955, its mating PNP, is the same way, and this, in a PNP makes sense.
2N 3055 TRANSISTOR FULL
Huge heat sink is required in this circuit, as 2N3055 transistors produce large amount of heat at full load. Continuous collector current (Ic) of 15A. The device is suitable for switching and amplification. This design can produce a current of 20 amps with little modification (use proper rating transformer and a huge heat sink with fan). The 2N3055 from Multicomp is a through hole, NPN transistors in TO-3 metal can package. NPN transistors are usually used with the emitter going directly to the ground, and the collector somewhere far from the ground. 0-28V, 6-8A Power Supply Circuit Diagram using LM317 and 2N3055. It has its collector "grounded" to the case, and the base and emitter to the two pins. The transistor 2N3055 is packaged in a TO3 case.
