The circuit diagram of a 100W powerful audio amplifier circuit is shown below. VQDElectronic Parts,Electronic Components distributor,memory,flash, integrated circuit,Original Product How to use a TIP122 Transistor? Maintain the temperature from 65C to +150 C. VQDElectronic Parts,Electronic Components distributor,memory,flash, integrated circuit,Original Productįrom the overheating, this transistor can be protected by using a heatsink. A base resistor must use for providing the required current on the base terminal. This transistor shouldn’t use when the circuit is operated above 100V and the load shouldn’t provide above 5A. To get good performance through this Darlington transistor, maximum ratings must maintain to below. VQDElectronic Parts,Electronic Components distributor,memory,flash, integrated circuit,Original Product How to Protect a TIP122 Transistor in a Circuit? So this transistor is a perfect choice for your requirement. This transistor can be controlled easily through a logic device for switching maximum power loads for amplifying max current. VQDElectronic Parts,Electronic Components distributor,memory,flash, integrated circuit,Original Product This transistor is used for controlling high current loads & also used wherever high amplification is necessary This transistor is simply controlled through a microcontroller which is called a logic device but care must be taken to verify if the microcontroller can capable of 120mA. This transistor can be connected to the microcontroller’s o/p & logic devices for controlling below 5A loads. This transistor can also be used as an amplifier & audio pre-amplifier. ![]() The application circuits of this transistor mainly include a battery charger, power supply, motors driving, etc. ![]() This transistor can be used as a switch within different electronic circuits to drive different loads below 5A based on its features. VQDElectronic Parts,Electronic Components distributor,memory,flash, integrated circuit,Original Product Where to use TIP122 Transistor/Applications? NPN transistors from the same family are TIP121, TIP120, TIP122 whereas PNP Family transistors are TIP126, TIP125 & TIP127. The TIP127 transistor is the complement transistor of the TIP122. Quantity in a pack from the factory is 200.Max Operating & Storage Temperature Ranges from -65 to +150 C.This is an NPN Darlington type transistor.This transistor is available in the TO-220 package.The features & specifications of a TIP122 transistor include the following. Pin3 (Emitter): This pin is used to drain the current.Pin2 (Collector): The flow of current will be there throughout this pin.Pin1 (Base): This pin controls the transistor biasing.VQDElectronic Parts,Electronic Components distributor,memory,flash, integrated circuit,Original Product TIP122 Pin Configuration & Symbol This transistor includes three pins where each pin and its function are discussed below. The pin configuration of a TIP122 Transistor includes the following. VQDElectronic Parts,Electronic Components distributor,memory,flash, integrated circuit,Original Product TIP122 Transistor Pin Configuration The manufacturing of this transistor can be done like a switch & amplification purposes. ![]() As the name suggests, the term Darlington means when the two transistors are available in a single pack for enhancing the gain at the o/p. The TIP122 is a Darlington NPN transistor and it is very popular for its high current gain & high current. VQDElectronic Parts,Electronic Components distributor,memory,flash, integrated circuit,Original Product What is TIP122 Transistor? This kind of transistor bears 100 volts in the region of both the emitter & collector terminals because it can be utilized mainly for high loads. This transistor includes a decent collector current like 5A & the gain is approximately 1000. The Darlington NPN transistor-like TIP122 includes Darlington braces & it works like a normal transistor however includes a Darlington pair.
