onsemi New Silicon Carbide Family

EliteSiC MOSET, Diodes and Modules

onsemi's new silicon carbide family, the ‘EliteSiC’, introduces three new members to the series. With reliable, high-efficiency performance for energy infrastructure and industrial drive applications, the 1700 V EliteSiC MOSFET and two 1700 V avalanche-rated EliteSiC Schottky diodes highlight onsemi’s position as a leader in industrial silicon carbide solutions.

The onsemi 1700 V EliteSiC MOSFET features higher breakdown voltage (BV) SiC solutions that comply with high-power industrial application requirements. Both 1700 V avalanche-rated EliteSiC Schottky diodes enable high-voltage operation at elevated temperatures with high efficiency thanks to SiC technology.

5 kVrms 4.5-A/9-A Isolated Dual Channel Gate Driver

NCP51561

The onsemi NCP51561 gate driver boasts dual-channel isolation and impressive current capabilities, with 4.5-A and 9-A source and sink peak current, respectively. Designed to drive power MOSFETs and SiC MOSFET power switches efficiently, the NCP51561 offers quick and matched propagation delays.

With internal galvanic isolation of 5 kVrms and functional isolation between the two output drivers, the NCP51561 is capable of operating at a working voltage of up to 1500 VDC. This driver offers versatility and can be used in various configurations, including two low-side switches, two high-side switches, or a half-bridge driver with adjustable dead time. The ENA/DIS pin offers the option for simultaneous shutdown of both outputs.

Additionally, the NCP51561 features important protective functions such as individual under-voltage lockout for each gate driver and a Dead Time adjustment function.

onsemi Silicon Carbide (SiC) MOSFETs

NTBG022N120M3S

The new onsemi family of 1200V M3S planar SiC MOSFETs boasts optimization for swift switching functions. Utilizing planar technology, these MOSFETs reliably handle negative gate voltage drive and sudden spikes on the gate. For optimal performance, a 18V gate drive is recommended, though these devices still perform well with a 15V drive.
