Muktilar I pulled this transistor out of screen power supply board- it was free: We Supply, You Satisfy! Q1 can be replaced by ca any transistor, the one you mention should do fine. Sign up using Email and Password. I did notice the pinouts are different. Company expending price, no more bargain with retail quantity.

The transistor is a semiconductor device and its use to regulate the supply current or voltage. It can be used as a switch in electrical circuits and also use as an amplifier. Here we list the applications of transistors. Transistors are used in digital and analog circuits as a switch. Cellular phones would be one of the most widely used applications of transistors.
Every cell phone uses a transistor amplifier. Transistors are used in building some of the integrated circuits IC. The microprocessor includes more than billion of transistors in each chip.
Transistors are used in almost every electronics devices from stoves to computers and pacemakers to aircraft.
Darlington transistor pairs are often used in touch- and light-sensing devices. After knowing some brief everyday uses of transistors, We take look into some important transistor applications in details : Transistor use as a switch : In most of the applications, transistors are used as a switch in circuits.
If the electronic circuit uses the transistor as a switch, then the biasing of the transistor either use PNP transistor or an NPN transistor that we must have to see. A transistor basically operated in three different modes, an active region, saturation region, and cut-off region. The other two operating regions of transistor Saturation Region and the Cut-off Region were used to operate a transistor switch. Transistor is operated as a switch in only this two operating regions.
When we apply the voltage at the base terminal of a transistor then switching operation is performed. So that, the transistor acts as a short circuit and we can say transistor is in OFF condition. The collector current flows through the transistor. In that case, switching connection load here LED lamp is connected to the output side with a reference point. In a previous article, we discuss in detail about the transistor amplifier circuit and how the transistor amplifier works?.
In earlier, vacuum tubes are used for the same applications but after the invention of the transistor, transistor take place in almost all small power electronics applications. Because of the transistor, the size of IC reduced. Transistor has following brief advantages for uses in some practical applications : Smaller size so less space required in the device High voltage gain Require low supply voltage for operation No heating problems during operation Solid state device So, they are mechanically so strong.
By using the transistor in IC the size of produced IC is so small that it can be easily portable. Read also — Applications of semiconductor Summary : The transistor is the basic semiconductor device which uses for regulating the current and voltage in small electronics circuits. Transistors are used in many amplifying circuits for amplifying weak signals.
Now a days, They are used in almost every electronics devices. Cell phones contain a transistor circuit as a sound amplification circuit.
Transistors are so small in size so that the size of modern IC reduced and we got benefited. They are uses in some aerospace applications also. So by the one line, we can say, because of the invention of transistor modern electronics is possible. If you have any question related to this topic feel free to ask in a comment. Thank you.
