Hello, readers welcome to the new post. We will learn Difference between IGBT and MOSFET. These two components are transistors that are used in electronic circuits. These two modules are regulated through the use of volts.
In this post, we will cover their different parameters to find the differences. So let’s get started Difference between IGBT and MOSFET
Difference between IGBT and MOSFET
What is IGBT
- The IGBT full form an insulated gate bipolar transistor comes with 3 pins and is used as an electronic switch. It was made to provide high efficiency and switching instantly.
- It comes with 4 layers of NPNP that are regulated with a metallic oxide semiconductor gate. design
- The design of IGBT is like the thyristor having an MOS gate, the thyristor functions not it performs but working transistor if done with working range.
- It is used for switching power amplifiers with high power circuits, variable frequency drivers variable speed refrigerator
IGBT Types
- IGBT comes with 2 basic types according to the N+buffer layer, the IGBT type comes with the N+buffer layer, called punch-through IGBT, and the 2nd type of non-punch-through IGBT.
- According to different features, types are also called symmetrical and unsymmetrical IGBTs.
- Symmetrical IGBT comes with the same value of forward and reverse breakdown volts.
- The asymmetric IGBT comes with low reverse breakdown as compared to forward breakdown volts
- Symmetric IGBT used for ac circuits and DC circuits uses Asymmetric IGBT.
What is MOSFET
- MOSFET is known as a metal oxide semiconductor field effect transistor, and its feature is that voltage defines the device conductivity level.
- It is part of switching signals and amplifier functions. Its feature is to vary conductivity with voltage connected and used for switching electronic signals.
- MOSFET is commonly used for analog and digital circuits. The gate pin is made with silicon dioxide and offers isolation by avoiding charge flow from the gate to the conducting channel.
- The MOSFET is a common device in digital circuits as compared to transistors since their larger number can connected on a single microprocessor.
- They are made with the use of P or N-type semiconductors, and pairs of MOS transistors used for making switching circuits with low power use in CMOS logic combination.
IGBT vs MOSFET
- The full form of IGBT is an insulated gate bipolar transistor, and MOSFET’s full form is a metal oxide semiconductor field effect transistor.
- IGBT has three terminals, and MOSFET has four terminals.
- The names of IGBT pins are emitter gate transistors, and MOSFETs are the source, gate-drain, and substrate.
- IGBT comes with a PN junction, and MOSFET does not have a PN junction.
- IGBT is used for mid to high levels of current, and MOSFET handles low to medium current.
- MOSFET handles less power than IGBT.
- MOSFET used for higher frequency than IGBT
- Forward volts for IGBT are less than the MOSFET.
- Off time for MOSFET is less than IGBT.
- The switching speed of IGBT is less than MOSFET.
- For handling transient currents and volts, IGBT is used rather than MOSFET.
- Saturation volts of MOSFET are less than IGBT.
- Prices of IGBT are higher than the MOSFET.
