The SQJQ980EL-T1_GE3 is an array chip module designed and built by Shanghai Queer Microelectronics Co., Ltd. It is a N-channel field effect transistor array featuring low on-resistance, low gate charge and fast switching. It is part of the company\'s series of advanced semiconductor devices and is used in many applications including telecommunications, consumer electronics, automotive and industrial electronics.

The SQJQ980EL-T1_GE3 chip module provides 9 evenly spaced insulated floating gate transistors. The gate insulator is made from a thin layer of silicon nitride and the drains and sources are bonded directly to the drain and source pins, respectively. The low gate charge and low on-resistance combined with the ultra-wide Vds enable the transistors to show superior performance with speeds exceeding 35 mAmps.

The main application fields of the SQJQ980EL-T1_GE3 are mainly in control and switching applications. It can be used for high and low side control, power switches, as well as circuit protection, motor control and gate drive applications. Other applications include rectication, output buffering, voltage clamping, current limiters and pulse generators in electronic circuit designs.

The working principle of the SQJQ980EL-T1_GE3 involves the controlled movement of charge carriers when a gate voltage is applied. This application of the transistor relies on the movement of charge carriers near the gate, which produces a depletion region at the interface between the source and drain regions. This depletion region creates a barrier and when a gate voltage is applied, charge carriers are moved away. Depending on the gate voltage, the current channel will either be in full enhancement mode or in depletion mode.

The depletion mode, also referred to as the normally off state, occurs when the gate voltage is close to or below the threshold voltage of the array. In this state, the operations are established through the application of a reverse bias voltage across the gate junction. The current channel is blocked and the array is in a state of shutdown. On the other hand, full enhancement occurs when a forward bias is applied to the gate junction and the current channel is created, allowing the operation to continue. The full enhancement mode is usually referred to as the normally on state.

To summarize, the SQJQ980EL-T1_GE3 is a floating gate transistor array designed by Shanghai Queer Microelectronics Co., Ltd. It is used in a variety of applications, from power switches and control circuits, to output buffering and gate drive applications. It uses controlled breakdown of the gate junction in order to control the current flow, either through the depletion or the full enhancement mode. The SQJQ980EL-T1_GE3 is an advanced semiconductor device for both industrial and consumer applications.
