Circuit Protection


IXYS manufacture an extensive range of MOSFETs (Metal Oxide Semiconductor Field Effect Transistors) which are used for high frequency switching control of power electronic systems. IXYS offers various MOSFET technology covering a large range of voltage and switching frequencies.

The IXYS MOSFET range includes: Trench Power MOSFET, TrenchT2™ Power MOSFET, Polar MOSFET, IXYS’ Polar™ HiPerFET, Legacy (Standard) MOSFET, Legacy HiPerFET™, Q-Class Power MOSFET, Q-Class HiPerFET™, Q2-Class HiPerFET™, Linear Power MOSFET, Depletion-Mode MOSFET, Legacy (Standard) P-Channel MOSFET, PolarP™ P-Channel MOSFET, TrenchP™ P-Channel MOSFET and CoolMOS™ * Power MOSFET.



Extended FBSOA Linear Power MOSFETs

IXYS' Extended FBSOA Linear Power MOSFETs are specifically designed for applications that require Power MOSFETs to operate in their current saturation region. These devices feature low static drain to source on-resistances and provide unparalleled performance and reliability in controlled current output applications. 

Depletion-Mode MOSFETs

Depletion-Mode Power MOSFETs do not require energy or gate voltage for turn on, they operate in a "normally-on" mode. The "normally-on" operational mode of these devices combined with an enhanced linear operating capability allows for an ideal device selection in current sources, current regulators, solid-state relays, level shifting, active loads, start-up circuits and active power filters.

PolarP™ P-Channel Power MOSFETs

IXYS' Polar technology features a proprietary cell design that improves overall device efficiency and performance. This technology platform reduces on-state resistance by as much as 30% and the gate charge by 40% compared to legacy counterparts. These devices offer low conduction and switching losses with a low input capacitance. 

TrenchP™ P-Channel Power MOSFETs

IXYS' Trench cell design features an ultra low Rds(on) minimising conduction losses and boosting improved operating and thermal efficiencies. The TrenchP™ P-Channel MOSFETs are suitable for high-side switching where a simple drive circuit referenced to ground can be employed, circumventing additional high-side driver circuitry commonly involved when using an N-Channel MOSFET.

Very High Voltage Power MOSFETs

The VHV N-Channel power MOSFETs are specifically designed to cater for demanding, fast-switching applications that require blocking capabilities of 2.5kV to 4.5kV. These Power MOSFETs are also ideal for parallel operation due to the positive temperature coefficient of their on-state resistance. Parallel operation with these devices provides a more cost-effective solution than using series-connected, lower-voltage MOSFETs. 


IXYS' ISOPLUS i4-PAC IGBT modules are available in 600V, 1200V and 1700V in a range of 18A-65A. IXYS offer 3,4 and 5 leaded packages for various circuit topologies. DCB base plate features: 2500V electrical isolation, low thermal resistance, increased power and temperature cycling, saves space, replaces multiple discretes, reduces parasitic inductance and capacitance and reduces EMI.
