Transistors are the fundamental parts of the recent electronic devices. They are available in two types i.e. NPN and PNP transistors. Based on the technical aspect and utilization, both types come with different benefits and advantages. Today, I am going to discuss the details on the Introduction to 2n3792. It is a PNP (positive-negative-positive) silicon bipolar power transistor mainly used for amplification and medium speed switching. It is manufactured using epitaxial planer process and comes in TO-3 casing.

I’ll cover each and everything related to this transistor so you don’t need to go anywhere and find all information in one place. Let’s explore what is this about, its main applications and everything you need to know.

Introduction to 2n3792

  • The 2n3792 is a PNP bipolar transistor which is mainly used for amplification and medium speed switching applications.
  • It consists of three layers where one N-doped layer is housed between two P-doped layers.
  • It has three terminals called emitter, base, and collector. All these terminals are different in terms of their doping concentrations. The emitter is highly doped as compared to base and collector terminals.
  • In this transistor, base-emitter is more positive with respect to base and collector. While negative biased voltage is applied at the base terminal.
  • It is a current controlled device where small current at the base side is used to control the large current at other terminals.

  • In this PNP transistor, current directions and voltage polarities will be reversed as compared to NPN transistors.
  • It works in a similar way to NPN transistor i.e. both are used for amplification purpose where small current at the base side is used to control the large current at the emitter and collector side, however, there is one exception, unlike NPN transistor, holes are diffused through base from the emitter and collected by the collector.
  • This PNP transistor is rarely used for amplification purpose because conduction carried out by the movement of electrons is considered more valuable than conduction carried out by the movement of holes.
Pinout of 2n3792
  • Following figure shows the pinout of this PNP transistor. It consists of three terminals.

1. Base

2. Emitter

3. Collector

  • Voltage is applied at the base terminal, which draws small current.
  • The output current obtained at the collector terminal is highly dependent on the voltage applied at the base terminal. This process is used for amplification purpose.

  • Current at the emitter terminal is equal to the sum of current at the base and collector side. The emitter is highly doped so it exhibits more current as compared to other terminals.
  • In this transistor current direction is reversed as compared to NPN transistor. In this case, current flows from collector to emitter.
  • Voltage polarities are also reversed. Negatively biased voltage is applied at the base terminal in order to initiate holes reaction which is then used to control the large current at the other terminals.
  • As the name suggests, this is a bipolar junction transistor where conduction is carried out by both charge carriers i.e. electrons and holes, but holes are majority charge carriers in this case. While electrons are majority charge carriers in NPN transistors.
Absolute Maximum Ratings of the 2n3792
  • Following figure shows the absolute maximum rating of the 2n3792.

  • These are the stress ratings that play an important role in the selection of this transistor for electronic circuits.
  • If stress ratings exceed the absolute maximum ratings, they can damage the device.
  • Similarly, if these ratings are applied for the maximum period of time above normal operating conditions, they can effect the reliability of the transistor. Before you pick this transistor for your project, make sure, it exhibits and undergoes same ratings as defined by the manufacturer.
  • Power dissipation is 150 W and these absolute maximum ratings are taken at the absolute junction temperature around 200 ºC.
  • Thermal resistance is 1.17 ºC/W which is the measure of resistance to the heat flow.
Applications
  • This transistor is used for medium speed switching applications.
  • It is also used for an amplification purpose.
