What else can I help you with?
What are PNP and NPN?
In most discrete bipolar junction transistors the substrate is the collector. In monolithic integrated circuits the bipolar junction transistors are electrically isolated from the substrate, either by reversed biased junctions or insulator (e.g. sapphire). Some older bipolar junction transistor types (usually made with germanium) the substrate is the base. In bipolar point contact transistors the substrate was the base.
What is the difference between a bipolar transistor and a field effect transistor?
A bipolar transistor uses both majority and minority charge carriers for conduction, while a field effect transistor primarily relies on majority charge carriers. Field effect transistors have a higher input impedance compared to bipolar transistors. Additionally, bipolar transistors are current-operated devices, while field effect transistors are voltage-operated devices.
What do digital circuits mostly use?
Bipolar Transistors and Diode's .
What is the center section of a transistor called?
in bipolar transistors it is called the basein field effect transistors it is called the channel
What applications would prefer the bipolar junction transistors over the field effect transistor?
bjt is bipolar device whr fet is unipolar....fet is input resistance thts y fet gain is less compared to bjt..... The applications that will prefer bipolar junction transistors to field effect transistors are applications that require fast switching.
What is btj transistors?
They are NPN and PNP. BJT mean bipolar junction transistors. there are two P-N junctions in BJT transisters.
What is the purpose of an IGBT?
An Insulated Gate Bipolar Transistor (IGBT) is a semiconductor device that combines the characteristics of both bipolar transistors and MOSFETs, primarily used for switching and amplification in power electronics. Its main purpose is to control high voltages and high currents efficiently, making it ideal for applications like motor drives, inverters, and power supplies. The IGBT's ability to handle large amounts of power with low switching losses makes it essential in renewable energy systems and industrial equipment.
Why h parameters are used?
They are one standardized way of describing the characteristics of bipolar transistors.
What has the author Peter Ashburn written?
Peter Ashburn has written: 'Sige Heterojunction Bipolar Transistors'
Do people use bipolar junction transistor today?
Yes people still use bipolar junction transistors today because of its high switching speed.
Why are MOSFETs used in motor control circuits instead of bipolar junction transistors?
Actually either can be used.
What has the author Richard Charles Jaeger written?
Richard Charles Jaeger has written: 'Low frequency noise sources in bipolar junction transistors' -- subject(s): Transistors, Frequency response (Dynamics)
