In today's tutorial, we are gonna have a look at detailed Introduction to TIP2955. It is a harmonizing silicon power transistor which is designed to use in universal tenacity power amplifications and swapping submissions. It is a PNP transistor and has a casing of TO-247. It is the complementary device for the  TIP3055 NPN transistors. It is used in such applications which need high power input supply.It is a common expedient used in numerous manufacturing schemes where acoustic intensification is obligatory. Its constructions are good-looking much the alike rejecting for the extreme power tolerance that is somewhat smaller. In today’s post, we will have a look at its protection, wreck, fame, applications, etc. I will also share some links where I have allied it with other microcontrollers. You can also get more material about it in comments, I will guide you more about it. So, let’s get started with a basic Introduction to TIP2955. 

Introduction to TIP2955

  • It is a harmonizing silicon power transistor which is designed to use in universal tenacity power amplifications and swapping submissions. It is a PNP transistor and has a casing of TO-247.
  • This transistor exits into the class of power transistors. Power transistors can endure high power indulgence deprived of any destruction.
  • Due to the restrictions of the transistor suite type, it is permanently compulsory that a power transistor is equestrian on an appropriate heat sink in other to bind the device’s maximum rated power deprived of harm.
  • This transistor finds extensive use in Power Swapping schemes such as inverters, and output periods of acoustic amplifiers where they are linked in push-pull with a corresponding power transistor type.
  • When used in an acoustic amplifier scheme, it is sensible to enterprise the power transistor from a pre-amplifier phase as most power transistors have little current gain.introduction to tip2955, tip2955 pinout, tip2955 working, tip2955 features, tip2955 applications, tip2955 rating, tip2955 working, tip2955

    Pinout of TIP2955

  • These are the main pinout of TIP2955 which are well-defined beneath.
  • Pin#Type                                        Parameters
    Pin#1EmitterThe emitter is for an outside enterprise of current.
    Pin#2BaseThe base manages the biasing of the transistor. It caprices the condition of the transistor.
    Pin#3CollectorThe collector is for the current inward movement. It is connected to the load.
    Lest see a diagram of the pinout.

TIP2955 as Voltage Regulator

  • Now we discuss how it works as the voltage regulator. For this, we discuss the circuit diagram.
  • Here is the circuit illustration of a potent 12V regulator that can carry up to 15 A of current. The communal voltage regulator IC 7812 (IC1) is rummage-sale to keep the voltage at stable 12V and three TIP 2599 power transistors in parallel are underwired in series permit style to increase the output current.
  • The 7812 can deliver only up to 1A and respite of the current is provided by the series permit transistors. The 15A bridge B1 does the work of rectifying the stepped downcast AC input.
  • The C1, C2, and C3 capacitors in this circuit are working as a filter. The 1A fuse F1 defends the IC1 from an excess of current in circumstance if the pass transistors flop. The 15A fuse F2 shields the complete circuit (particularly the pass transistors) from overcurrent.
  • When you are working on such circuits which are using current transformers high current consuming bridge circuits this circuitry is expensive and you can try this only if there is a solemn essential.introduction to tip2955, tip2955 pinout, tip2955 working, tip2955 features, tip2955 applications, tip2955 rating, tip2955 working, tip2955
