The AFGHL50T65SQDC uses the latest field stop IGBT and SiC Schottky diode technology to offer low conduction and switching losses in multiple power applications, including those that will benefit from reduced reverse recovery losses, such as totem pole based bridgeless power factor correction (PFC) and inverters.

The device co-packages a silicon-based IGBT with a SiC Shottky barrier diode, resulting in an excellent tradeoff between the lower performance of silicon-based solutions and the higher cost of entirely SiC-based solutions.

Modern electric vehicle applications not only use energy to travel but, in some cases store energy which may be used to power the home at peak times. This requires a bi-directional charger that must have high efficiency switching to ensure that energy is not wasted during the transfer. In this use case, the IGBT with external SiC diode is significantly more efficient than a MOSFET solution as there are no associated forward or reverse recovery losses.

Key Features

  • AEC-Q101 qualified
  • Maximum Junction Temperature : TJ = 175°C
  • For systems requiring greater current capability, a positive temperature co-efficient allows for easy and convenient parallel operation
  • Rated for 650 V operation
  • Can handle continuous currents up to 100 A @ 25°C (50 A @ 100°C) as well as pulsed currents up to 200 A
