Next-Generation onsemi 1200 V EliteSiC M3S Devices Enhance Efficiency
of Electric Vehicles and Energy Infrastructure Applications
New portfolio includes fast-switching MOSFETs and half-bridge power integrated modules withindustry’s lowest Rds(on) per switch position in industry standard packages
SCOTTSDALE, Ariz. – May 9, 2023 – onsemi (Nasdaq: ON), a leader in intelligent power and sensing
technologies, today announced the release of the latest generation of 1200 V EliteSiC silicon carbide(SiC) M3S devices, which enable power electronics designers to achieve best-in-class efficiency andlower system cost. The new portfolio includes EliteSiC MOSFETs and modules that facilitate higherswitching speeds to support the growing number of 800 V electric vehicle (EV) on-board charger (OBC)and energy infrastructure applications, such as EV charging, solar and energy storage systems.
Also part of the portfolio, are new EliteSiC M3S devices in half-bridge power integrated modules (PIMs)
with industry leading lowest Rds(on) in a standard F2 package. Targeting industrial applications, themodules are ideally suited for DC-AC, AC-DC and DC-DC high power conversion stages. They provide
higher levels of integration with optimized direct bonded copper designs to enable balanced current
sharing and thermal distribution between parallel switches. The PIMs are designed to deliver high power
density in energy infrastructure, EV DC fast charging and uninterruptible power supplies (UPS).
“onsemi’s latest generation of automotive and industrial EliteSiC M3S products will allow designers toreduce their application footprint and system cooling requirements,” said Asif Jakwani, senior vicepresident and general manager of the Advanced Power Division, onsemi. “This helps designers todevelop high power converters with higher levels of efficiency and increased power densities.”
The automotive-qualified 1200 V EliteSiC MOSFETs are tailored for high-power OBCs up to 22 kW andhigh voltage to low voltage DC-DC converters. M3S technology has been developed specifically for highspeed switching applications and has the best-in-class figure of merits for switching losses.
