Structure

The SI4456DY-T1-GE3 is constructed on an advanced planar process and packaged in a power HVFET2, a surface mount device with high-voltage insulation. The dielectric strength of the device is rated at 500 V, making it suitable for its intended use in higher voltage power conversion and motor drive applications. The transistor is available in a range of output voltages, current ratings and temperature ranges.

Working Principle

The SI4456DY-T1-GE3 works on the principle of majority carriers where a voltage is applied to the gate of the transistor. This in turn changes the conductivity of the channel and modulates the flow of current between the source and drain electrodes. When an appropriate voltage is applied to the gate, a positive charge accumulates in the channel, resulting in greater current flow than at a lower voltage. A higher voltage applied to the gate effectively blocks the flow of current, effectively ‘turning off’ the transistor.
