Discover the technological choices made by United Silicon Carbide Inc. (UnitedSiC) for its most advanced SiC JFET and its associated features.

UnitedSiC UJN1205K 1200V SiC JFET

Silicon carbide-based device penetration is expanding in industrial applications. JFET is one of them. UnitedSiC offers two types of medium-voltage (1200V) SiC JFETs, with the UJN1205K achieving the highest current (38A).

This JFET  is marketed as the ideal solution for circuit protection because of its ability to handle peak temperatures and  limit current by a rapid decrease due to self-heating. The device also offers a low on-resistance of 45mΩ, but a very high current density of 4.08 A/mm2 at 25°C,  thanks in large part to its trench structure with special openings for contacts.

UnitedSiC employs in its JFET structure a unique angled implantation process to improve threshold voltage control, and a silicide for both gate and source contact to boost  contact resistance.

Owing to its design, the device’s cost is very competitive regarding its special steps.

Also, the packaging is optimized for cost-savings.

This report presents a deep technology analysis of the UJN1205K device, assembled in a TO247 package. Also included is a  production cost analysis, and comparisons with its JFET counterpart from SemiSouth. This comparison highlights the differences in the design technology choices and the electrical/geometrical parameters.
