IXYS received FDA approval for its IGBT in portable defibrillators, making it the leading provider of chips for defibrillators made in North America. IXYS’ market position is bolstered by regulatory hurdles (FDA approval) that essentially act as a barrier to entry. Additionally, IXYS’ power semis are being designed into advanced diagnostic systems (MRIs, x-rays, ultrasound, surgical lasers); the chips control the immediate high voltage power demands of this equipment.
