Littelfuse, Inc. 200V - 2500V N-Channel Linear Power MOSFETs with Extended FBSOAs IXTK46N50L

When Power MOSFETs are used in the linear-mode operation, as opposed to their conventional switch-mode one, they are required to endure substantially high thermal and electrical stresses due to the simultaneous occurrence of high drain voltages and currents; these extreme stresses can cause typical devices to fail. Littelfuse Linear MOSFETs have been designed to address these kinds of device failures – the FBSOAs are “extended” when the positive feedback of electro-thermal instability is suppressed, giving rise to larger “operating windows.” The FBSOAs are guaranteed at 75°C. Designed for linear operation Guaranteed FBSOA at 75°C Avalanche rated International standard packages UL 94 V-0 Flammability qualified (molding epoxies)
