What is BD136?
A general-purpose with medium power BD136 transistor is mainly used for audio amplification & switching purposes. This kind of transistor belongs to the family of PNP. This transistor works like a switch to drive or handle a maximum of 1.5A of load continuously through 45V of load voltage.
What is TIP42C transistor?
Tip42c is a medium power transistor mainly used for amplification and switching purpose. It is made up of silicon material and falls under the category of PNP transistors. The voltage across collector and emitter terminals is 100V and the voltage across base and collector terminals is 100V.
Does triac need heat sink?
Therefore, TJ = 40°C + 1.49 W × 55°C/W = 122°C. This is below the TJMAX of 125°C. Therefore, the triacs can be operated without heatsinks.
How do you connect a transistor?
To connect the transistor as a switch in a circuit, we connect the output of the device that will switch on the transistor to the base of the transistor. The emitter will connect to ground of the circuit. And the collector will connect to the load that the transistor will turn on and the supply voltage of the circuit.
How can a transistor control a motor?
Attach high-current load (i.e. the motor or light) to its power source, and then to the collector of the transistor. Then connect the emitter of the transistor to ground. Then to control the motor, you apply voltage to the transistor’s base.
What is PNP and NPN?
It’s easy to remember that NPN stands for Negative-Positive-Negative and PNP stands for Positive-Negative-Positive transistors. Let’s take a closer look at how NPN and PNP transistors work. NPN transistor is powered on when enough current is supplied from the transistor base to the emitter.
What is transistor PNP and NPN?
PNP switches On by a low signal whereas NPN switches ON by a high signal. As we are aware that in PNP transistor, the P represents the polarity of the emitter terminal and N represents the polarity of the base terminal.
What is the use of tip 42c transistor?
The TIP42C can be used in various general purpose tasks in electronic circuits. With the max collector current of -6A, it is capable of driving high power switches, relays, transistors etc. Moreover with its max collector-emitter voltage of -100V, one can use it in circuits that require high voltages under 100V.
