Pnp Transistor As A Switch

Transistor switches are often used to take the low-level output from logic circuits to turn on or turn off a particular device. The actual transistor used as a switch is not critical in these applications. Virtually any general purpose NPN or PNP transistor can be used as a switch.

01/10/2012 · A short video describing how to use a BC558 PNP transistor as a switch. For more information check out the related blog post - http://langster1980.blogspot.c...

01/09/2017 · This video explains the working of a PNP transistor as a switch.

11/08/2017 · Transistor as switch : The application of an PNP transistor is to work as a high side switch. To explain with a PSPICE model, PN2907A transistor has been selected. The first important thing to bear in mind to use a current limiting resistor at base. Higher base currents will damage a BJT. From the datasheet the maximum continuous collector ...

21/06/2018 · The base of the transistor is used to switch current through the collector and emitter. When the base is between 0V and 0.7V it is switched off and when above 0.7V it is switched on and allowing the current to flow from the collector to the emitter. In PNP type transistor we need a Negative voltage at the base terminal for turning on the ...

19/10/2019 · PNP Transistor Switch. The PNP transistors can also be used as a switch, this time the difference is that the load is connected to the ground (0v) and the PNP transistor switches the power to it. The base terminal is connected to ground or zero volts (LOW) as shown to turn the PNP transistor operating as an “ON” switch.

10/04/2019 · High-side transistor switch. The opposite of the low side switch is the high side switch. This transistor connects between +V and the load. Because of how transistors work, these can be a little more difficult to use in an Arduino or Raspberry Pi circuit. Typically these use a PNP

Difference Between an NPN and a PNP Transistor. Before we talk about the differences between NPN and PNP transistors, we will first discuss what they are and their similarities. Both NPN and PNP are bipolar junction transistors (BJTs). BJTs are current-controlled transistors that …

Alternatively, we can use a PNP transistor to create a high-side switch: Similar to the NPN circuit, the base is our input, and the emitter is tied to a constant voltage. This time however, the emitter is tied high, and the load is connected to the transistor on the ground side.

26/06/2014 · If the circuit uses the Bipolar Transistor as a Switch, then the biasing of the transistor, either NPN or PNP is arranged to operate the transistor at both sides of the “ I-V ” characteristics curves we have seen previously.
