Navitas unveils 5th-generation SiC MOSFET platform with 35% improved switching figure of merit
Navitas Semiconductor has launched its 5th-generation GeneSiC technology platform, a 1200 V SiC MOSFET line based on what the company calls Trench-Assisted Planar (TAP) architecture. The design combines the ruggedness of a planar gate structure with the performance benefits of a trench in the source region. The headline improvement is a 35% better RDS(on) x… Read more »
Infineon launches isolated gate driver ICs with opto-emulator input for SiC migration
As the power electronics industry shifts from silicon IGBTs to SiC MOSFETs—driven largely by the efficiency demands of EV inverters, onboard chargers and DC fast charging—one persistent headache has been the gate driver. Legacy designs built around optocouplers and opto-emulators typically need significant rework to handle SiC’s faster switching speeds and higher noise immunity requirements…. Read more »
Vishay releases 1,200 V SiC MOSFET power modules for EV chargers in SOT-227 package
Vishay Intertechnology has introduced five 1,200 V silicon carbide (SiC) MOSFET power modules in the industry-standard SOT-227 package: VS-SF50LA120, VS-SF50SA120, VS-SF100SA120, VS-SF150SA120 and VS-SF200SA120. Vishay says the modules target medium- to high-frequency power conversion, where switching losses and thermal headroom limit efficiency, including EV offboard, switched-mode power supplies (SMPS), DC-to-DC converters, uninterruptible power supplies (UPS),… Read more »
