APT80SM120S

APT80SM120S is a single power MOSFET (metal oxide semiconductor field-effect transistor) designed for use in applications that require high current, such as motor control, discontinuous conduction mode (DCM) movement and power factor correction (PFC). The device can also be used in other high-power applications such as power supplies and lighting systems.

APT80SM120S Application Field

In motor control applications, APT80SM120S is used in DC-DC converters for switching applications. It has an ultra-low Qg (Gate Charge) that offers fast switching speed and better system performance. The device is also suitable for gate drive circuits where short rise and fall times are important. It is extensively used in AC motor drives allowing for greater power efficiency and higher performance. The device also suits lighting applications where low voltage performs with low total harmonic distortion (THD).

APT80SM120S is a popular choice for those who need fast switching between power states in a power supply or system. The device has high current handling capability, allowing for high output power and improved system efficiency. It is effective for applications such as switching mode power supplies (SMPS), low voltage DC-DC converters and power factor correction (PFC) motors.

In addition, APT80SM120S offers soft switching in high-temperature and inductive load applications. This allows for higher reliability, power efficiency, and improved thermal performance. It also provides protection against short circuit damage, commutation failure, and overvoltage.

APT80SM120S Working Principle

APT80SM120S is a voltage sensing field effect transistor (FET), which means it requires less gate current to operate than a traditional FET. This is because the MOSFET has built-in internal capacitors which store a portion of the voltage applied to the gate, enabling the FET to switch quickly when the voltage applied to the gate is greater than the threshold voltage.

Once the voltage applied to the gate is greater than the threshold voltage, the FET becomes “ON”. The FET then acts as a low resistance path and allows current to flow from drain to source. This current is then used to drive whatever load the device is connected to, such as a motor or light.

When the current is removed, the MOSFET automatically switches “OFF.” The FET is then able to act as a very high resistance and blocks current from flowing from the drain to the source. This protective feature is extremely useful for applications that require precise control, such as power supplies and motor control.

APT80SM120S is a single power MOSFET that provides high current capability, low gate charge, fast switching speed, and improved system performance. It is designed to be used in motor control, DCM (Discontinuous Conduction Mode) motor drive, PFC (Power Factor Correction) motor drive, and other power applications. The device is easy to use due to its high current capability and fast switching speed, as well as excellent protection and thermal performance.
