Silicon Carbide (SiC) MOSFETs

Our SiC MOSFETs are designed to be fast and rugged and include system benefits from high efficiency to reduced system size and cost. MOSFETs are metal–oxide–semiconductor field-effect transistors with insulated gates. These silicon carbide MOSFETs have a higher blocking voltage and higher thermal conductivity than silicon MOSFETs, despite having similar design elements. SiC power devices also have a lower state resistance and 10 times the breakdown strength of regular silicon. In general, Systems with SiC MOSFETs have better performance and increased efficiency when compared to MOSFETs made with silicon material.

There are many advantages to choosing SiC MOSFETs over silicon MOSFETs, such as higher switching frequencies. High-temperature development is also not a concern when using SiC MOSFET modules because these devices can operate efficiently even in high heat. Additionally, with SiC MOSFETs, you benefit from a more compact product size because all components (inductors, filters, etc.) are smaller.

IGBTs
Insulated Gate Bipolar Transistors (IGBTs) that offer maximum reliability in high performance power conversion applications.
MOSFETs
Si MOSFETs control current flow between source and drain terminals via gate voltage. They're widely used in power amplifiers, voltage regulators, and switching circuits for their efficiency, speed, and power-handling capabilities.
Silicon Carbide (SiC) Modules

SiC Modules contain SiC MOSFETs and SiC diodes. The boost modules are used in the DC-DC stages of solar inverters. These modules use SiC MOSFETs and SiC diodes with voltage ratings of 1200V.

A Silicon Carbide (SiC) Module is a power module that operates with Silicon Carbide semiconductors for its switch. The purpose of a SiC power module is the transformation of electrical power through switches to improve system efficiency.

The primary function of SiC Modules is to transform electrical power. Silicon Carbide offers an advantage over silicon because, with less resistance to move away from the source (due to increased efficiency), SiC devices can operate at a higher switching frequency. A SiC based system is also more compact and lightweight than a silicon solution, allowing for smaller designs. Therefore, SiC devices are the ideal solution for situations where you want to increase efficiency and improve your thermal management.

Gallium Nitride (GaN) FETs
GaNEXUSTM Gallium Nitride (GaN) FETs are enhancement‑mode discrete GaN HEMTs that leverage wide‑bandgap material properties to deliver fast switching, low gate and output charge, and superior efficiency compared to silicon power transistors. These characteristics enable higher operating frequencies, reduced magnetics, and increased power density across low/medium, high and ultra-high voltage power conversion applications.
Gallium Nitride (GaN) Integrated Power
GaNEXUSTM Integrated Power includes GaNEXUS Drive, GaNEXUS Smart, and GaNEXUS Control, where each combines a GaN switch together with potential combination of additional features: gate driver, current sensing, protection, and control, in a single device to simplify design, reduce parasitics, and accelerate time to market.
Gate Drivers
GaN, IGBT, FET, MOSFET, H-Bridge MOSFET, and SiC MOSFET inverting and non-inverting drivers ideal for switching applications.
Digital Isolators
Products that use a high frequency modulated signal to transmit high speed digital data across a capacitive isolation barrier.
Si/SiC Hybrid Modules

Si/SiC Hybrid Modules contain IGBTs, silicon diodes and SiC diodes. They are used in the DC-AC stages of solar inverters, energy storage systems and uninterruptible power supplies.

Hybrid Si/SiC (Silicon/Silicon Carbide) modules are integrated IGBT power modules with high power density. They have lower switching losses than nonhybrid modules, and they can also work at higher temperatures than other types of semiconductors.

Si/SiC hybrid modules have several uses including being used in high-power applications that need low losses. They may also be used in higher temperature environments than comparable Si modules. For systems requiring high-frequency switching, Si/SiC hybrid modules provide better efficiency.
