“What is the difference between igbt and mosfet ?
What is the full form of igbt ?
What is the full form of mosfet ?
You all must have this kind of questions in your mind. Below article will solve this puzzle of yours. Just take a look.”
MOSFET vs IGBT – Here we are going to define difference between MOSFET and IGBT.
What is a MOSFET ?
1. MOSFET full form is “Metal Oxide Semiconductor Field Effect Transistor”.
2. There are two types of MOSFET i.e., n-channel MOSFET and p-channel MOSFET. It can also be classified as Depletion MOSFET and Enhancement MOSFET.
What is a IGBT ?
1. IGBT full form is “Insulated Gate Bipolar Transistor”.
2. There are two types of IGBT i.e., NPT-IGBT (i.e. non punch through) and PT-IGBT (i.e. punch through).
MOSFET vs IGBT
| S. No. | MOSFET | IGBT |
| 1. | MOSFET stands for “Metal Oxide Semiconductor Field Effect Transistor”. | IGBT stands for “Insulated Gate Bipolar Transistor”. |
| 2. | MOSFET Terminals are gate, source and drain. | IGBT Terminals are emitter, collector and gate. |
| 3. | MOSFET gate/control signal occurs between the gate and source, and its switch terminals are the drain and source. | IGBT gate/control signal takes place between the gate and emitter, and its switch terminals are the drain and emitter. |
| 4. | MOSFET has High Switching Frequency (> 100kHz) | IGBT has Low Switching Frequency (<20kHz) |
| 5. | MOSFET has low power handling (<250W). | IGBTs has high power handling (> 250W). |
| 6. | Low-voltage, low-current and high switching frequencies favour MOSFETs. | High-voltage, high-current and low switching frequencies, on the other hand, favour IGBTs. |
| 7. | MOSFET used in SMPS (Hard switching greater than 200 KHz). | IGBT used in UPS (constant load, typically at low frequency). |
