The IXTY08N50D2 is a depletion mode N-channel MOSFET designed for normally-on operation in applications such as audio amplifiers, start-up circuits, and protection circuits. It is packaged in a TO-252 (DPAK) case measuring 0.35 g and rated for a maximum drain-source voltage of 500 V and a continuous drain current of 800 mA. The gate-source voltage ranges from -20 V to +20 V, with a transient tolerance of ±30 V. The on-state resistance is 4.6 Ω at 25°C and 400 mA, and the device features a forward-biased body diode with a typical voltage drop of 0.8 V. The molding epoxies meet UL 94 V-0 flammability classification. Thermal resistance from junction to case is 2.08 °C/W. Operating and storage junction temperatures range from -55 °C to 150 °C.
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).
