Silicon carbide technology has quickly been adopted into power systems used for electric vehicles (EVs) and renewable energy applications, offering numerous advantages including greater efficiency, lower costs, and smaller system footprints. Discover why silicon carbide’s versatility has led to its wide adoption across various systems applications.
Onsemi offers comprehensive vertically integrated SiC manufacturing capacity that spans boule growth, substrate processing, epitaxy, device fabrication and top-of-the-line ICs and modules. Discover three compelling reasons to select our EliteSiC family solutions as you transform sustainable energy for tomorrow.
High Temperature
SiC is one of the few semiconductor materials capable of withstanding high temperatures, making it an indispensable material in high-temperature power and sensing applications. Due to its outstanding physical properties – high saturation electron drift velocity, fast switching speed, and higher breakdown electric field than silicon (Si), SiC results in increased efficiency at reduced costs in systems like power converters, power transistors and motor drivers.
Industrial applications like pumps, oil refining operations and mines often place equipment under immense strain in harsh and hazardous conditions, demanding performance and reliability regardless of temperature variations. Silicon carbide (SiC) sensors have become the go-to material for intelligent IoT sensors in such settings to enable devices to function under demanding and hazardous circumstances.
SiC’s high temperature resistance makes it an ideal material choice for industrial IoT devices operating in harsh and toxic environments, like mines and pump facilities, where access may be challenging or prohibitively expensive. SiC enables these devices to withstand higher operating temperatures while remaining reliable over their lifespans.
SiC products require a rigorous quality and reliability methodology that starts at design stage. onsemi has applied its silicon-based power semiconductor experience to develop an extensive process and test capability capable of qualifying and safely releasing SiC products up to 1200 V safely and responsibly. This approach involves rigorous design methodology, stringent production monitoring, manufacturing control measures, screening procedures, screening plans, as well as thorough qualification plans.
Högspänning
Silicon Carbide (SiC) can withstand high voltage, making it suitable for the elimination of parasitic components and increasing system efficiency. Furthermore, SiC allows greater power density due to a smaller footprint and lower component count.
Onsemi’s EliteSiC family of MOSFET and diode solutions offers a broad selection of product families that have been designed to accommodate different application-withstand voltage ratings up to 1700 V. With customized packages to meet customer applications and higher reliability, lower switching losses, and faster recovery times than their Si counterparts, EliteSiC devices provide superior solutions.
Onsemi’s EliteSiC power devices are assembled using raw SiC material in the form of a boule. After being processed through manufacturing steps, this transparent wafer is cut up into individual device die for assembly and testing purposes.
Onsemi stands out from other semiconductor manufacturers with its vertical integration model and provides customers with one source for high-quality power devices that can withstand the high temperatures and voltages associated with electric vehicle (EV) traction inverters. This enables automotive OEMs and their tier 1 suppliers to accelerate time to market by rapidly iterating toward optimal designs while reducing risks with faster test turnaround, especially important when dealing with an emerging technology such as SiC.
Hög effektivitet
Silicon carbide’s superior material properties allow it to push current through smaller areas with reduced thermal resistance. This leads to greater efficiency as more power is delivered at lower footprint; plus this reduced size means fewer passive components which further lower total bill of materials costs and weight.
SiC solutions typically feature lower bill of material (BOM) and system costs than their Silicon-based equivalents, leading to significant cost-cutting benefits in industries like energy infrastructure, industrial drives and EV charging stations.
onsemi’s advanced packaging techniques also help lower costs by improving heat dissipation and permitting thinner form factors, thus decreasing cooling system size requirements – an expense often associated with high-performance devices.
Compact device packages also help minimize parasitic effects and enhance system reliability – key considerations in high-speed applications that have become common for both electric vehicles (EV) and energy storage systems. Onsemi’s 1.7kV EliteSiC MOSFETs and Schottky diodes with an avalanche rating of 1.7kV make excellent solutions for use in inverters, off-board chargers, DC-DC converters.
Låg kostnad
Silicon carbide is an integral component in high-power power devices designed for electric vehicles (EVs) and energy infrastructure, yet with rapidly rising demand surpassing supply, silicon carbide shortages have arisen and therefore development and deployment of intelligent power solutions must occur more quickly.
One of the primary challenges facing original equipment manufacturers and automotive OEMs when it comes to supply chains is ensuring components can arrive on time. Delays could cost revenue or compromise emission reduction targets; that is why it’s imperative to partner with an integrated vertically integrated supplier who can offer supply assurance throughout the design cycle.
Onsemi has made substantial investments to meet this market need by expanding their capacity and moving toward 8-inch platform capacities at their Bucheon fab, as well as expanding substrate operations by fivefold.
Onsemi will also quadruple device and module production at this location, enabling it to offer industry-leading devices at highly competitive price points.
These improvements will enable customers to implement intelligent power and sensing technologies for megatrends like vehicle electrification and safety, sustainable energy grids and industrial automation. Onsemi provides a wide variety of power devices such as SiC MOSFETs and gate drivers in different packages to fit various applications and environments as well as reference designs, application notes, simulation models/tools and more to speed adoption of such technologies.
