Tranzistor 2n30558/13/2023 ![]() ![]() The JLH 10 Watt Class A Power Amplifier is a Good example.Īlso look at Non Class A audio Power Amp Circuits like this one. Look at the Circuit Diagram of ANY Audio power amp using 2N3055 Power Transistors and you will see how its used. Hence the Collector junction is connected to the Body of the transistor, so that it can be connected to a Heat sink to keep it cool. It will allow a much larger current to flow between the collector and the emitter. LAOJIA 2N3055 Power Transistors,5pcs 2N3055 Power Transistors NPN to-3 Metal Case 15A/60V Set of 5 Transistors. The output current of 7805 flows to a base of 2N3055. These devices can also be used in power switching circuits such as relay or solenoid drivers, dctodc converters, inverters, or for inductive loads requiring higher safe operating area than the. Put the 2N3055 This method might solve the problem. Hence the Collector-Base Junction dissipates practically ALL the power (Power = Voltage x Current and Current thru the collector & Emitter are almost identical) High-Power Transistors These PowerBase complementary transistors are designed for high power audio, stepping motor and other linear applications. ![]() (Almost All the voltage across the transistor) The Base-Collector junction reverse biased.The Base-Emitter Junction Forward Biased (0.7 Volts) Details, datasheet, quote on part number: 2N3055 Features, Applications Power dissipation 25☌ DC current gain hFE 4 A VCE ( Sat) 1.Commercially, it was used in many linear power supplies, audio amplifiers and low frequency. However, generally, it is the same as ANY Other transistor.ĪLL Transistors when operated linearly (for analog signals - Non Switching applications) will ALWAYS have: 2N3055 is a general purpose NPN power transistor manufactured using the base epitaxial process, mounted in a hermetically sealed metal package, and designed for general purpose switching and amplifier applications. The 2N3055 was designed for medium-current and high-power circuits. DISCLAIMER: SIGMA Surplus and SIGMA Group are not affiliated with nor an authorized distributor. The 2N3055 is a Power Transistor, ie its characteristics are optimised for delivering High Power. Model: 2N3055 Product Type: Power Transistor Made In: India. The 2N3055 in TO3 is rated for upto 115 Watts power dissipation. The TO3 casing is the largest and provides the best heat dissipation, when connected to an adequate Heat sink. The 2n3055 is an NPN transistor functions like a normal transistor that includes three terminals such as emitter, base, and collector. The 2N3055 is available in TO-3 casing as well as TO220. It is still available, but other better (More power, better frequency Response) have now displaced its pole position. The 2N3055 was the mainstay of audio amplifier power transistors for over a decade or 2, since it was launched. ![]()
