Hello, readers welcome to the new tutorial. We will discuss Difference between thyristor and MOSFET. A thyristor is known as SCR which is a solid-state semiconductor component having 4 P and N layers and MOSFET is metallic-based FET and created through the oxidation process of the silicon part.
Here we will discuss different parameters to find the differences between thyristor and MOSFET. So let get started
Difference between thyristor and MOSFET
What is MOSFET
- MOSFET is also called a unipolar FET transistor. It comes with 3 pins that are source, drain, and gate. Source and drain are taken from semiconductor layers that connect and make channels.
- With the use of a control electrode or gate, we can regulate the current flow on the channel.
- The main feature of this transistor is the bipolar transistor working feature which means MOSFET control voltage.
- In simple words, it controlled voltage at the gate point. It has an oxide material layer that is silicon dioxide over the electrode.
- It has two main types P and N channel MOSFET. Their work is the same but different in their inner structure. P channel MOSFET inner design has a conductive channel of P-type materials and N channel MOSFET is N-type material.
What is Thyristor
- These controlled electronics turn on the module, which needs a trigger pulse to operate.
- It has four layers of NPNP or PNPN.
- In some cases, it is an analog of SCR
- It works as a bistable switch when the gate has a current connection and operation continues when the voltage on the component is not reversed.
- It is used to control a high current value through 2 points that connect to a control point
- It exists in two categories of structural armament.
- In Firestone, there are two terminals and the other one is three terminals.
- They have applications where high values ​​of volts and current are involved.
- It is used for AC control and zero crossing control.
- Its operation is synchronous if it works in phase at the voltage indicated on its terminals.
- There are three guidance modes, it has reverse, forward, and forward guidance mode
It has three intersections. - It has three anode-cathode terminals and a gate.
- Used in phase fire control units
- Its power-handling capability is better than that of a diode.
- It required a higher value of voltage to operate than a diode.
- It is more expensive than a diode.
- This is heavy equipment.
Thyristor vs MOSFET
- Larger volts needs for thyristors and also high current while MOSFET operates on medium-level volts and high current
- Thyristor has less switching frequency than MOSFET
- Losses during operation for thyristors are less and MOSFET has high
- A thyristor is current controlled and MSOFE is volts controlled device
- MOSFET needed continuous supply to operate while the thyristor needed one pulse
- Thyristor gets off through line communication and MOSFET through the gate
- For series circuits thyristor used for volts equal circuits for thyristor and MOSFET not used
- There is no 2nd breakdown for the thyristor and MOSFET has fewer chances for 2nd breakdown
- MOSFET is more sensitive than the thyristor
 Differences between Thyristor and MOSFET
Thyristor
- It does not have a Thermal runaway
- it is less sensitive to temperature.
- its main type is High voltage current device
- It needs a separate switch to turn it off
- It needed a single pulse to turn on
- its switching speed is low
- it has less resistive input impedance.
- it controls current.
MOSFET
- It does not have theraml run away
- It is highly sensitive to temperature.
- It not needed turn of switch
- Its swithcing speed is high
- it has high resistive input impedance
- It is voltage controlled devices
Differences between Thyristor and Transistor
Thyristor
- It is 4 layer device
- its main terminals are anode-cathode and gate
- it has high operation over voltage and current
- It needed gate pulse for turn on
- it has less power losses than transistors.
Transistor
- It has 3 layers
- its main pinouts are the emitter, collector, and base
- it has lower operation over voltage and current than thyristor
- It needed continuous supply for current control and turning on.
- it has high power loss.

Faqs:
What is the difference between SCR and MOSFET?
- The basic difference between thyristor and MOSFET is that a thyristor called SCR has 4 alternating P and N layers and MOSFET is a metal-based field effect transistor and ade with controlled oxidation of the silicon side.
What is the main difference between a thyristor and a transistor?
- Transistors provide linear amplification and gain over differnt types of input signals, so best for analog and radio frequency uses. Thyristors are used for switching and not used for linear amplification or gain.
What are the advantages of thyristor over MOSFET?
- Thyristors do not have moving parts that are used for increasing reliability and longevity than electromechanical switches.
- Thyristors can on and off in microseconds helping the fast control of electrical power.
What is the major difference between a thyristor and SCR?
- The thyristor is 4-layer semiconductor device and has P and N materials in PNPN configuration. Thryristos has 3 electrodes anode, cathode and gate called the control electrode. The common type of thyristor is a silicon-controlled rectifier (SCR)
