Working Principle

The SI8441DB-T2-E1 is a N-channel enhancement-mode power MOSFET. It can be used to switch large voltages and currents with low on-resistance and low power consumption. It consists of a substrate, gate oxide, source, drain and body. When a voltage is applied to the gate, the gate oxide creates an inversion layer between the gate and the substrate that allows electrons to flow from the source to the drain. This creates an electric field between the source and the drain that enables the device to switch large voltages and currents without dissipating too much power. The low gate-to-source capacitance of the device also minimizes power consumption when the device is switching.

The SI8441DB-T2-E1 can be used in a variety of applications due to its low on-state resistance, high switching speed and low gate-to-source capacitance. It is able to switch large currents with low switching losses and is also able to withstand high surge current. The device can also operate at up to +125°C junction temperature, making it suitable for automotive, telecom and industrial applications.
