The IXGA4N100 is a popular transistor device that originates from the single-IGBT family. IGBTs (Insulated Gate Bipolar Transistors) are a type of transistor that combines the high-speed switching characteristics of Field Effect Transistors (FETs) with the low saturation voltages of bipolar transistors. The device itself is composed of a layer of insulation, a gate field effect and a bipolar base. Due to the multiple semiconductor characteristics, it is a versatile device that can be used in a variety of high-power electronic systems.

The IXGA4N100 is a common high-voltage, medium-current IGBT module and is an excellent choice for many applications including power supplies, inverters, motor speed and position control, DC/DC converters, drives, lighting and home appliances. The device has a rated collector-emitter voltage of 1200V, a peak collector current of 4A and a maximum gate - emitter voltage (V_ge) of 12V. In addition, it guarantees a current-gain bandwidth (fT) of 18MHz and a maximum junction temperature of 150°C.

When looking at the technical specifications of the IXGA4N100, one of the most important characteristics is its high switching speed. This is due to the low on-state voltage drop (V_CE(sat)). This results in fast switching times of up to 25µs with no necessity for slow current gain recovery times. This is beneficial when applications require high surge currents with minimal voltage droop.

When the IXGA4N100 is used in the primary side of a switching power supply, its high speed, low losses, and low EMI characteristics make it an ideal choice. This is because the low on-state resistance helps in avoiding unwanted conduction losses, while its high-speed switching capability and low EMI, allows the device to maintain a high efficiency and low EMI during operation. Moreover, its high voltage rating and fast switching speed also allow it to be used as a gate drive in high power converters.

Aside from its use on the primary side, the IXGA4N100 has proved to be highly effective when used on the secondary side of the circuit as well. When used on the secondary side of the system, the IXGA4N100 can provide protection from short-circuiting, reverse current flow and overvoltage conditions. This is largely due to its fast turn-off times which make it capable of switching off much faster than most other transistors.

The working principle of the IXGA4N100 is based on that of a standard IGBT device. In essence, the device has an insulated gate electrode, which is responsible for controlling the current flow within the device. When the voltage is applied to the gate, the device becomes conductive, allowing the electrons to flow from the collector to the emitter. Conversely, when the voltage is removed from the gate, the device becomes non-conductive, thus inhibiting the current flow. This is the basic operation of the IXGA4N100.

The IXGA4N100 is a reliable and powerful semiconductor device that has a multitude of applications in the electronics industry. Its combination of excellent switching characteristics, a high voltage rating, low on-state voltage drop, and fast switching speeds makes it an attractive choice for high power applications, making it one of the most popular transistor devices in the market.
