Discrete IGBTs

Offering a large range of industry-leading IGBTs from IXYS and IXYS UK Westcode

Discrete IGBTs are an insulated-gate bipolar transistor (IGBT) three-terminal power semiconductor device which is primarily used as an electronic switch. Discrete IGBTs feature high efficiency and fast switching capabilities and consist of four alternating layers controlled by a metal oxide semiconductor gate structure.

IXYS IGBTs by GD Rectifiers

Xtreme Light Punch Through (XPT™) Planar IGBTs

The XPT IGBTs are an extremely rugged technology platform of IGBTs, which are ideal for critical applications that require low conduction and low switching losses with a 10 μs short circuit withstand capability. IXYS XPT IGBTs have lower saturation voltage and low total switching energy (Eon + Eoff). A large portfolio of module packed Planar XPTs are also available for applications such as UPS, Motor drive and solar inverters.


Xtreme Light Punch Through (X2PT™) Planar IGBTs

The X2PT are IXYS’ second generation of XPT IGBTs. Features are 10 μs short circuit capability, 175°C max junction temperature, further reduce VCEsat) and lower turn-off losses (Eoff) resulting in a competitive performance to the latest trench devices at reduced Rth. These IGBTs are most commonly used for Motor Inverters.


Xtreme Light Punch Through (XPT™) Trench IGBTs

The XPT Trench IGBTs are the latest development in the IGBT range. This range starts at 650V and features a low VCE(sat) and an extremely low switching losses, making this the ideal range for fast switching applications whilst retaining good SOA rating and a positive temperature coefficient.


1600V & 1700V Low Sat IGBTs

The Low Sat IGBTs are designed for capacitor discharge applications, featuring a low voltage, high power density and high peak current capability. These IGBTs provide a complete solution for power conversion applications.


1600V & 1700V High Speed IGBTs

This family of 1600/1700V IGBTs are targeted for high voltage applications that require 10 μs short circuit withstand capability. IXYS offer a fast switching ‘A’ version 1700 V NPT IGBTs and both are suitable for high voltage switching applications with switching frequencies upwards of 50 kHz.


Very High Voltage (2500V – 4000V) IGBTs

IXYS boost a unique range of discrete 2500V, 3000V and 4000V VHV IGBTs with collector current ratings spanning from 2A to 75A. The voltage and current ratings of these devices, coupled with simplified MOS gate-control makes this IGBT a favourite amongst engineers.



BiMOSFETs have the combined strengths of MOSFETs and IGBTs. IXYS BiMOSFETs feature a monolithic intrinsic diode which can reduce die count in many applications.

IXYS UK Westcode IGBTs

IXYS UK’s IGBTs are a pioneer of Press-Pack IGBT technology, they offer a large range of class leading devices with voltage ratings of 1.7kV (900V DC link), 2.5kV (1.25kV DC link) and 4.5kV (2.8kV DC link).

The production of these devices is free from wire and solder bonds which all but eliminates the problems of mechanical fatigue associated with conventional modules. Internal stray inductance in both the gate connections and emitter connections is vastly reduced when compared to conventional modules leading to improved ruggedness and short circuit behaviour, which is further enhanced by direct cooling of the emitter side of chip.

IXYS devices feature state-of-the-art punch through (PT) process, which yields exceptional values VCE(sat) and quiet switching behaviour despite the high voltage ratings yet the devices feature a positive temperature coefficient making them suitable for reliable parallel operation. These devices are available with or without integral anti-parallel diode; a range of complimentary extra fast recovery diodes optimised for use with these IGBTs are available now.

IXYS UK press-pack IGBTs feature exceptional power cycling performance; typically an order of magnitude better than modules, making them highly suited to applications such as metals and traction drive systems where there are repeated cyclic power demands. Press-pack IGBTs have a stable short circuit failure mode which alongside safety benefits, makes them an ideal choice for medium and high voltage applications where series connection is required. Stable short circuit failure mode allows for the design in of n+ redundancy without additional bypass switches and costly explosion proof enclosures. Typical examples include HVDC, FACTs, Active VAr controllers/compensators and medium voltage drives. In applications above 4MW press-pack IGBTs offer exceptional power density, far exceeding that achievable with comparable modules in multi-level/MMC based converters.

IXYS UK’s press-pack IGBTs are largely backwardly compatible with standard 2.5kV and 4.5kV GTOs in many applications such as AC drives. This makes these parts a simple and economical path to upgrade or refurbish equipment that previously used GTOs, such as locomotives or medium voltage drives. They are suitable for all cooling options including direct liquid immersion. Complementary gate drives, mounting clamps and passive components are available.
