UnitedSiC launches six new 650V/1200V D2PAK-7L SiC FETs
Silicon carbide (SiC) power semiconductor maker United Silicon Carbide Inc (UnitedSiC) of Princeton, NJ, USA has further expanded its field-effect transistor (FET) portfolio with the introduction of six new 650V and 1200V options, all housed in the industry-standard D2PAK-7L surface-mount package. Available in 30, 40, 80 and 150mΩ versions, these latest SiC FETs represent another step in accelerating migration to SiC across applications such as telecom/server power supplies, industrial battery chargers and power supplies, electric vehicle (EV) on-board chargers and DC-DC converters, says the firm.
The D2PAK-7L SiC FETs support significantly heightened switching speeds, with a Kelvin source connection improving gate drive return performance, as well as offering industry-leading thermal capabilities. Through the use of Ag sintering, die attachment can be done on conventional PCBs as well as complex insulated metal substrate (IMS) arrangements. In addition, they exhibit what is claimed to be excellent creepage and clearance figures of 6.7mm and 6.1mm, respectively, so the highest degrees of operational safety can be assured even at elevated voltages.
“Through the fast switching capabilities of these latest FETs, alongside the superior thermal performance resulting from Ag sintering, we continue to bring performance, reliability, size and layout benefits to the power designer,” says Anup Bhalla, VP engineering.
The new D2PAK-7L devices are fully supported by UnitedSiC’s FET-Jet Calculator. Utilizing this free online resource, engineers can assess the different operational parameters needed for their application, carry out detailed performance comparisons and then identify which is the best SiC solution for their design requirements quickly and with confidence, says the firm.
Pricing for the new 650V D2PAK-7L SiC FETs (in 1000-unit quantities, FOB USA) range from $3.27 for the UF3C065080B7S to $7.54 for the UF3SC065030B7S. For the 1200V D2PAK-7L devices, prices range from $3.10 for the UF3C120150B7S to $10.91 for the UF3SC120040B7S. All devices are available from UnitedSiC authorized distributors.
