IGBTs, or Insulated Gate Bipolar Transistors, are semiconductor devices that are widely used in various power applications. An IGBT, like any other transistor, is a three-terminal device consisting of an emitter, a collector, and a gate. IGBTs however, combine the switching ability of power transistors with the low "on" resistance of MOSFETs or JFETs, allowing them to deliver higher switching speeds and lower power losses. IGBTs are traditionally used in high-current and/or high-voltage applications such as motor control, switching DC/AC power supplies, and UPS systems.

The NGTB15N120IHLWG is a single IGBT package from Infineon Technologies. This package consists of a single IGBT with a 1700V blocking voltage rating, a 35A continuous collector current, and a 6.7Ω “on” resistance. The total power dissipation rating of the NGTB15N120IHLWG is 133 Watt and the junction to case thermal resistance is 0.5°C/W, meaning that the device can safely dissipate high power without risking any damage.

The NGTB15N120IHLWG is commonly used in various medium-power applications such as solar inverters, Uninterruptible Power Supply (UPS) systems, static transfer switches, frequency converters, traction (railway) systems, and in induction heating applications. It is also used in various medium-power automotive applications, such as DC/AC inverters and 12V-24V converters.

The basic function of the NGTB15N120IHLWG is to allow the controlled flow of current by acting as a switch. When the current through the gate is increased, the IGBT is switched-on and the current flows unimpeded through the device. The NGTB15N120IHLWG has an internal body diode, meaning that it can also be used as a rectifier by applying a voltage across the emitter-collector terminals and then allowing the body diode to do the rest of the work. Essentially, the NGTB15N120IHLWG acts as a high-side switch, allowing a low power signal (gate voltage) to control a higher power device.

The NGTB15N120IHLWG is a common type of IGBT and as such has a unique set of advantages over other devices. It is relatively easy to replace with other devices that have the same dimensions, making it easy to replace in existing applications. The reverse blocking capability of the NGTB15N120IHLWG is also higher than that of other devices, making it more reliable and suitable for use in highly regulated applications. Additionally, the NGTB15N120IHLWG has a low turn-off delay time of 8μs, making it suitable for applications that require a fast turn-off time.

In summary, the NGTB15N120IHLWG is a single IGBT package from Infineon Technologies, designed for a variety of medium-power applications. The device is capable of handling high powers, up to 1700V blocking voltage, up to 35A continuous collector current, and up to 6.7Ω “on” resistance. It also has a low turn-off delay time of 8μs, making it suitable for applications that require a fast turn-off time. The NGTB15N120IHLWG is commonly used for applications such as solar inverters, Uninterruptible Power Supply (UPS) systems, static transfer switches, frequency converters, traction (railway) systems, and in induction heating applications.
