The UF3N170400B7S is a high-performance, Gen 3 silicon carbide (SiC) normally-on JFET that provides engineers with an ideal solution for over-current protection circuits, DC-AC inverters, switch-mode power supplies, power factor correction modules, motor drives, and induction heating applications.
This ultra-fast-switching, temperature-independent JFET, features ultra-low on-resistance (RDS(ON)) and gate charge (QG), along with low conduction and switching loss.
This voltage-controlled device is ultra-efficient, with a low RDS(ON) of just 400 mΩ at VGS = 0 V, low intrinsic capacitance, and is ideal for current protection circuits without the need for active control or cascode operation.
The RoHS-compliant UF3N170400B7S comes in an industry-standard D2P package, is halogen- and lead-free, and operates at an extended ‑55°C to 175°C temperature range.
