Thermal Resistance from Junction−to−Case R0JC = 1.52 C/WĮLECTRICAL CHARACTERISTICS of 2N3055(TC = 25 C unless otherwise specified)
#2n3055 transistor switching circuit series
A calculated resistor must be included in series with the base pinout of the transistor. This input switching signal can be anywhere between 1V and 12V ideally. The base is connected across the input signal through which the transistor needs to be switched ON or OFF. In the common emitter mode which is most frequently used configuration, the emitter pin is connected with the ground line or the negative supply line. Just like any other npn BJT, 2N3055 connections are also pretty straightforward.

Pinout Diagram How to Connect the Pinouts Collector−Emitter Saturation Voltage − V CE(sat) = 1.1 Vdc (Max) IC = 4 Adc.DC Current Gain or hFE = 20 −70 IC = 4 Amps (Collector Current).I have used 2N3055 transistor many number of times in many of my high current circuit applications without any issues. If you are an electronic hobbyist, you might have certainly used this very useful, and efficient power transistor at least once in your experiments. It does not store any personal data.In this post we comprehensively discuss the pinout function, electrical specification, and application designs for the power transistor 2N3055.

The advantages of a simple construction and high efficiency are set by the disadvantage of a wave output voltage which, in absence of a regulator is load dependent: at low loads the output may be well over 220 VAC. If a toroidal mains transforrner is -used, the, converter can be constructed as a very compact unit. If 2N3055 transistors are used, the power output will be about 90 watts.Īs the output transistors are driven into saturation, they should be mounted on very large (100 mm high fins) heat-sinks. If RCA 40411 transistors are used in the output stages, the current through the secondary wind- ing can be as high as 10 A, giving a possible power output of 180 watts. When T1 conducts, a current also flows through T3 this switches on T5 and this transistor connects one half of the secondary winding of mains transformer Tr across the 12-volt battery, if T2 conducts, transistor T6 switches the other half of the mains transformer across the battery. As T1 and T2 conrjuct§ alternately, the output stages also operate in 'push- pull". The circuit requires only six transistors, a mains transformer and some capacitors and resistors An astable multivibrator (AMV), consisting of transistors T1 and T2, provides a square-wave at a frequency ofabout 50 Hz. supply suitable for powering small electrical appliances, such as lights, soldering irons or electrical tools. Whether it’s in the car, boat, caravan or mobile home, this converter provides a mobile 220 V a.c.
