The SPP100N04S2-04 is a N-channel, silicon-based, field-effect transistor (FET) that is used for high-current,/high-power applications. It is commonly used in motor, high-current switching, and power-supply applications. The SPP100N04S2-04 is the most cost-effective solution in the SPP100N04S2 family of FETs. It has an RDSon rating of 1.55 Ohms and a drain-source resistance of 0.005 ohms.

Working Principle

The SPP100N04S2-04 operates on a basic principle: the gate voltage controls current that passes between the source and the drain. When a positive voltage is applied to the gate terminal, current begins to flow through the device. This current is known as “drain current” or “channel current”.

The degree of conducting current is determined by the voltage supplied to the gate terminal. As the voltage increases, more electrons are able to pass through the FET, and more current is collected in the drain terminal. Conversely, as the voltage decreases, fewer electrons are able to pass through the FET, resulting in lower drain currents. The degree of conducting current between the source and drain terminal is thus dependent on the gate voltage.

Applications

The SPP100N04S2-04 is typically used wherever a high-current load needs to be switched rapidly and accurately. The device is capable of carrying up to 100 amperes at 140V and dissipating up to 125W of power.

It is commonly used in power supply applications such as switched-mode power supplies (SMPS), uninterruptible power supplies (UPS) and DC to DC converters. It is also used in motor applications such as servo motors and brushless DC motors (BLDC). The SPP100N04S2-04 is a cost-effective solution for high-current, high-power applications such as these.

The SPP100N04S2-04 is also an ideal choice for higher-frequency applications such as DC-to-AC inverters, power factor correction (PFC) systems and Class-D audio amplifiers. The device’s low on-resistance and high-frequency switching capabilities make it ideal for these applications.
