Transistors - IGBTs - Single

The RJH65T47DPQ-A0#T0 transistor is a single IGBT (Insulated-Gate Bipolar Transistor) from the Renesas Electronics Corporation. It is a cornerstone of the company\'s power electronics lineup and a powerful solution for many industrial applications. This article will provide an overview of the IGBT device and its working principle, as well as discuss its application fields.

What is an IGBT?

The IGBT is an evolution of the MOSFET (Metal-Oxide Semiconductor Field-Effect Transistor). It is what is known as a ‘floating gate’ device, in which electrons can be trapped by the gate insulation to modify the conductivity of the channel. IGBTs are able to combine the power efficiency of a BJT (Bipolar Junction Transistor) with the compactness of a MOSFET. This makes them ideal for a variety of applications such as motor drive and control.

Working Principle

The RJH65T47DPQ-A0#T0 package is a three-terminal semiconductor device, consisting of an emitter, a collector and a base. These three terminals form both an N-channel and a P-channel MOSFET in parallel. The working principle of the IGBT is similar to a MOSFET; electricity is driven by the potential applied between the emitter and the base. However, unlike a MOSFET, where the electrical current is controlled by the voltage applied to the gate, in an IGBT a bipolar current flow is used to control the switch.

When a very small current flows through the base-emitter junction, a junction field-effect, called the body or substrate effect, modifies the switching characteristics, allowing the base current to be increased. This increase in current is the mechanism by which the IGBT is able to switch on much faster and with less power than traditional devices. The RJH65T47DPQ-A0#T0 has an operating voltage of 700V and a maximum collector current of 47A.

Applications

The RJH65T47DPQ-A0#T0 is suitable for a wide range of applications that require rapid switching of high currents. The device is well-suited for motor drives and control, plasma etching, switching of high-power devices, invertor circuits and bridge circuits. The device is also capable of switching half or full bridge loads such as induction cooking or other similar applications.

The device is also used in a wide range of automotive and industrial applications, including HVAC, motor drive and control, industrial robotics, and programmable logic controllers (PLC). With its wide operating voltage and current rating, the RJH65T47DPQ-A0#T0 is well-suited for many different applications requiring fast, reliable switching.
