SI5905BDC-T1-GE3

The SI5905BDC-T1-GE3 is an integrated two-element array structure FET developed by Vishay Siliconix. This device is designed to provide low resistance switching for loads related to high current, low voltage applications. This device is often used as an alternative to bulkiar MOSFETs, as it allows for more efficient power management due to its lower on-resistance and smaller packaging.–

The device structure consists of two independent N-channel depletion-mode FETs that are built in an arrayed configuration. Each FET has an individual drain connection and drain-gate connection. This allows the device to be suitable for higher voltage applications due to the dual drain connections. As such, the device has a higher current capacity and a wider range of operating voltages. In terms of its application field, the SI5905BDC-T1-GE3 is often used in power supplies, notebook power adapters, server power supplies, UPS systems, and any application where space saving, low resistance, and higher current capacity is needed. It can also be used in high voltage switching applications, such as load switching, DC-DC conversion, and motor speed control.

In terms of its working principle, the SI5905BDC-T1-GE3 functions through its two N-channel FETs, which act as an on/off switch to control the flow of current. When the control gate is high, the FETs are open, and no current can flow through them. When the control gate is low, the FETs are closed and current is allowed to flow through them. The device has two separate drain connections, each of which are connected to the two FETs. This allows the device to handle higher voltage applications and provides a more efficient power management. The device also has an integrated body diode, which helps to reduce the switching loss by providing a path for reverse current flow.

Overall, the SI5905BDC-T1-GE3 is a great choice for applications requiring low resistance, higher current capacity, and space saving. It is often used in power supplies, notebook power adapters, and various high voltage switching applications. It has a two-element array structure, which provides higher current capacity and wider operating voltages. Additionally, the integrated body diode helps to reduce the switching loss.
