Farnell brings Toshiba’s SiC MOSFETs to space saving industrial projects
The third generation Toshiba silicon carbide (SiC) MOSFETs are now available from Farnell. The 650V and 1200V SiC MOSFETs improve efficiency and save space in industrial applications, said the distributor.
Designers can realise enhanced efficiency, reduce size for industrial applications and provide up to 80 per cent improvement in both static and dynamic losses, said the company. The MOSFETs are suitable for use in a wide variety of demanding applications including switch mode power supplies (SMPS) and uninterruptible power supplies (UPSs) for servers, data centres and communication equipment. They can also be used for renewable energy, such as photovoltaic (PV) inverters and bi-directional DC/DC converters used for electric vehicle (EV) charging.
Farnell offers the 650V TW015N65C, TW027N65C, TW048N65C, TW083N65C and TW107N65C SiC MOSFETs. The “significantly reduced power loss enables development of solutions with higher power densities and lower running costs,” said Farnell. A key figure of merit (FoM) calculated as the product of drain-source on-resistance (RDS(on)) and gate-drain charge (Qg) to represent both static and dynamic losses has improved by approximately 80 per cent.
The SiC MOSFETs contain Toshiba’s embedded Schottky barrier diode, which is claimed to enhance the reliability of SiC MOSFETs by overcoming internal parasitic effects to maintain a stable device RDS(on).
The 1200V SiC MOSFETs are housed in an industry standard TO-247 package and can handle currents up to 100A and feature RDS(on) values as low as 15 mOhm.
Gate-source voltage range is -10V to 25V and gate-threshold voltage range is from 3.0V to 5.0V, which ensures predictable switching performance with minimal drift and permits a simple gate driver design, according to Farnell.
The devices have RDS(on) values from 15 to 140 mOhm (typical, at VGS = 18V) and drain-current ratings from 20A to 100A (DC at TC=25 degrees C).
These third generation Toshiba SiC MOSFETs are now available from stock at Farnell in EMEA, Newark in North America and element14 in APAC.
