The IXTH16N50D2 is a 500 V N-channel depletion mode MOSFET designed for normally-on operation in applications such as audio amplifiers, start-up circuits, and protection circuits. It is available in a TO-247 package, weighing 6 g, and features a maximum drain-to-source on-state resistance of 300 mΩ at 25°C and 8 A gate-source voltage. The device has a continuous drain current rating of 16 A and a power dissipation of 695 W at 25°C. Thermal resistance from junction to case is 0.18°C/W, and the operating junction temperature ranges from -55°C to 150°C. The molding epoxies meet UL 94 V-0 flammability classification. It includes a body diode with a forward voltage of 0.8 V to 1.3 V at 16 A and a reverse recovery charge of 7 μC.
As opposed to the enhancement-mode MOSFETs, these depletion-mode devices operate in a ‘normally-on’ mode, requiring zero turn-on voltage at the gate terminal. With blocking voltages up to 1700V and low drain-to-source resistances they provide simplified control and reduced power dissipation in systems that are continuously “on” (emergency or burglar alarms, for instance).
