What is the use of C945 transistor?
C945 is commonly used in electrical circuits that require a high-speed transistor with a low current, which is made up of three semiconductor regions: emitter, base, and collector. The base of the C-945 is doped with positive or P-type semiconducting material because it is a bipolar junction transistor.
What is a transistor switch?
A Transistor switch, which is used for opening or closing of a circuit, that means the transistor is commonly used as a switch in the electronic devices only for the low voltage applications because of its low power consumption. Transistor work as a switch when it is in cutoff and saturation regions.
How does a transistor switch work?
With a zero signal applied to the Base of the transistor it turns “OFF” acting like an open switch and zero collector current flows. With a positive signal applied to the Base of the transistor it turns “ON” acting like a closed switch and maximum circuit current flows through the device.
How do I use BC547 as a switch?
Useful Steps
- Place Transistor on a breadboard.
- Connect Emitter to the ground of the battery.
- Add LED & 330 Ohm Resistor to Collector of BC547.
- Connect 1k Resistor and Switch to Base of transistor.
- Power up the circuit with 9V Battery.
Which is the fastest switching device?
MOSFET
Detailed Solution. Amongst BJT, MOSFET, JEFT and Triode, MOSFET is the fastest switching device because of its quickest response.
Can we use transistor as a switch?
Using a transistor as a switch is the simplest application of the device. A transistor can be extensively used for switching operation either for opening or closing of a circuit. Meanwhile, the basic concept behind the operation of a transistor as a switch relies on its mode of operation.
What is BC547 used for?
BC547 is usually used for current amplifier, quick switching and pulse-width modulation (PWM). Therefore, if you need to control the speed of a motor or actuator in some of your projects, you can simply use this transistor to achieve it.
How does BC547 work as a switch?
This is how it works. It just bypasses the signal present of the collector while having active base condition. As soon as we press the button a signal (in form of voltage and current) will be received by the base of BJT which in turn allows electric current to pass from collector to emitter.
What is c945 transistor?
C945 Transistor Explained / Description: C945 is a general purpose NPN transistor used in wide variety of commercial and educational electronic circuits. It is manufactured in TO-93 package, the max load this transistor can drive is around 150mA or 0.15A that is enough to operate many devices in a circuit for example LEDs, Relays, ICs,…
What is the equivalent of a733 replacement for c945?
PNP Complementary of C945 is A733 Replacement and Equivalent: 2N2222, 2N3904, 2SC1815, 2SC3198 (Pin configuration of SOME transistors are different from C945, check pin configuration before replacing in a circuit)
What is the power output of a TO-92 transistor?
It comes in a to-92 package deal, this transistor can power max load around 150ma that is sufficient to operate many devices in a circuit for leds, relays, ics, transistors and different parts of electronics circuits. The saturation of this transistor is handiest 0. 3v dc it is also an excellent feature of this transistor.
How to run this transistor safely in a circuit?
To run this transistor safely in a circuit it is suggested to not operate it voltage over 50V, always connect the pins correctly and do not provide it load above 150mA because the max load this transistor can handle is 150mA. For best performance we suggest to not touch the max load limit always stay under it.
