The SI5445BDC-T1-E3 is one of the latest SiGe transistors developed by Siliconix. It is a high-voltage monolithic MOSFET, specifically designed for demanding applications in various fields, such as automotive, industrial and medical. This device is equipped with advanced features to reduce power consumption, increase efficiency, and improve overall performance.

The SI5445BDC-T1-E3 is ideal for applications that require high voltage and low R_DS(on) combined with low gate charge. It has very low on-resistance (R_DS(on)), which enables better efficiency and lower power dissipation when compared to other transistor types. It has a rated voltage of -100V to 28V and a maximum R_DS(on) of 0.2 ohm along with a maximum on-state drain current of 2.5A and a maximum off-state drain-source breakdown voltage of 40V.

The working principle of the SI5445BDC-T1-E3 is based on the MOSFET\'s intrinsic devices structure. The power supply voltage is applied to the drain terminal, and the gate terminal is connected to the body of the transistor. The body of the transistor acts as a gate electrode and controls the flow of electrons between the source and the drain terminals. When no voltage is applied to the gate, the transistor will be in a “cutoff” state and no current will flow between the source and the drain. When a voltage is applied to the gate, current will flow between the source and the drain.

The SI5445BDC-T1-E3 provides a unique combination of low on-resistance and high current-handling capabilities, making it an ideal device for a wide range of applications. It is suitable for use in automotive, industrial, and medical fields such as motor control, power management, and high-voltage circuit protection. It is also commonly used in solar, battery, and UPS power systems.
