The IXTN46N50L is an N-channel enhancement mode power MOSFET designed for linear operation, with a drain-source voltage rating of 500 V and a continuous drain current of 46 A at 25°C. It is packaged in a miniBLOC SOT-227B case with aluminum nitride isolation, weighing 30 g. The device has a maximum on-resistance of 0.16 Ω at 25°C and supports a pulsed drain current of up to 100 A. It features an extended forward bias safe operating area (FBSOA) and is rated for junction temperatures from -55°C to 150°C. The molding epoxy meets UL 94 V-0 flammability requirements. Thermal resistance from junction to case is 0.18 °C/W, and case to sink is 0.05 °C/W.
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.
