1. Is PNP transistor bipolar?
PNP transistor is a bipolar transistor. PNP transistor is a bipolar transistor used in electronic circuits to amplify, switch and control current. Its name "PNP" represents the three different semiconductor regions in its structure: two positive poles (P type) and one negative pole (N type).

2. Are bipolar transistors still in use?
Bipolar transistors are still in use and play an important role in many fields. Bipolar transistors, the full name of which is bipolar junction transistor (BJT), commonly known as triode, are electronic devices with three terminals, made of three parts of semiconductors with different doping levels. Its working principle involves the flow of two carriers, electrons and holes, so it is called bipolar.

3. Is BJT transistor a bipolar device?
BJT transistor is a bipolar junction transistor (Bipolar Junction Transistor, referred to as BJT), which is a bipolar device. BJT is composed of two PN junctions, divided into PNP and NPN types, and works through two PN junctions to achieve current amplification.
The working principle of BJT is to amplify the collector current by controlling the base current. When the base potential is higher than the emitter potential, the emitter junction is in a forward biased state, and the collector junction is in a reverse biased state. Since the majority carrier concentration in the emitter region is greater than that in the base region, most of the electrons injected into the base region pass over the collector junction and enter the collector region, forming a collector current, thereby achieving current amplification.
BJT is widely used in electronic circuits, such as amplifiers, switches, oscillators, etc., with amplification capabilities, linear amplification characteristics and high frequency response. -
4. What are the two types of BJT transistors?
There are two main types of BJT transistors: NPN and PNP.
NPN transistor
In an NPN transistor, current flows from the collector to the emitter. The base of an NPN transistor must be connected to a positive voltage for current to flow in. As the current flowing to the base increases, the transistor gradually turns on until the current is completely conducted from the collector to the emitter.
PNP Transistor
In a PNP transistor, the current flows from the emitter to the collector. Therefore, the base of the PNP transistor must be grounded. When the output current is small and the base is negative relative to the emitter, the transistor will turn on and a larger current will flow from the emitter to the collector. Basically, if the base and collector are negative relative to the emitter, the PNP transistor will conduct current from the emitter to the collector.
