Profile: Ixys Corp. is a manufacturer of power semiconductors and power modules for the global power market. Our product line includes power devices, RF power & pulsed power systems, laser diode drivers and solar devices. Our press-pack IGBTs (insulated gate bi-polar transistors) - capsule type devices with voltage ratings of 1.7 kV (900V DC link), 2.5 kV (1.25 kV DC link) and 4.5 kV (2.8 kV DC link). The construction of these devices is totally 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 behavior, which is further enhanced by direct cooling of the emitter side of the chip.These devices are based on a state of the art punch through (PT) process, which yields exceptional values VCE( sat), and quiet switching behavior despite the high voltage ratings; yet the devices feature a positive temperature co-efficient making them suitable for reliable parallel operation.
