MOSFET Technology
The MOSFET: a mainstay of power electronics
First developed in the 1970s, the Silicon (Si) MOSFET remains the most widely used power device globally. With its low gate drive power, fast switching speed, and advanced paralleling capability, power MOSFETs are used in a wide range of applications in sectors such as consumer electronics, transportation technology, and automotive applications.
Leveraging the advantages of the MOSFET
The voltage-controlled power MOSFET can operate at voltages up to 1 kV with high switching speeds and low power losses, with many advantages over current- controlled devices, such as BJTs, including:
MOSFETs are the ideal choice for multiple applications, including power supplies, DC-DC converters, motor controllers, and various RF and switching applications.
Choosing the right MOSFET
It seems as if manufacturers are continually launching new device families and showcasing their respective benefits. Individual MOSFETs within the same device family target different use-cases and, with such a wide choice, finding the optimal balance between price and performance can be difficult and time-consuming.
At the same time, MOSFET design presents a specific set of challenges. The gate driver circuit characteristics must match the required switching speed of the device while offering protection against factors such as overvoltage and unwanted EMI effects. While datasheets may give typical operating parameters, the actual performance of the MOSFET will depend on factors such as switching speed and operating temperature.
With considerations such as solution operating environment and cost also influencing the final decision, how can you be confident that you’ve chosen the right MOSFET for your solution?
