Did you know that overvoltage is one of the main reasons why MOSFETs burn out?

MOSFETs are semiconductor devices that primarily act as switches in circuits. When the gate-source voltage of a MOSFET exceeds its rated voltage, overvoltage occurs, leading to the MOSFET being burnt out. To prevent MOSFETs from burning out, we need to take measures to solve and prevent overvoltage issues.

Solving Overvoltage Issues:

1. Use Overvoltage Protection Devices: These devices are specifically designed to protect circuits from overvoltage damage. They can detect overvoltage in the circuit and automatically cut off the power to protect the circuit from overvoltage damage.

2. Use Capacitors: Capacitors can absorb overvoltage in the circuit, protecting the MOSFET from overvoltage damage. When designing the circuit, you can add an appropriately sized capacitor at the input of the MOSFET to absorb overvoltage.

3. Use Voltage Regulators: Voltage regulators can stabilize the voltage, preventing it from becoming too high and protecting the MOSFET from overvoltage damage. When designing the circuit, you can add an appropriately sized voltage regulator at the input of the MOSFET to stabilize the voltage.

Preventing Overvoltage Issues:

1. Design the Circuit Reasonably: When designing the circuit, choose circuit components, especially capacitors and voltage regulators, carefully to ensure the stability and reliability of the circuit. Additionally, pay attention to the circuit layout and connection methods to avoid overvoltage issues due to improper circuit layout.

2. Use Fuses: Adding fuses to the circuit can automatically cut off the power when overvoltage occurs in the circuit, protecting the circuit from overvoltage damage.

3. Enhance Circuit Maintenance: Regularly check circuit components and connections, replace damaged components, and repair faulty lines promptly to ensure the normal operation of the circuit.

In summary, in the process of circuit design and maintenance, we should pay attention to details, design the circuit reasonably, choose suitable components, and enhance circuit maintenance to ensure the stability and reliability of the circuit.
