The IXTA08N50D2 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 offered in a TO-263 package and has a maximum drain-source voltage rating of 500 V, with a continuous drain current of 800 mA and on-state resistance of 4.6 Ω at 25°C. The device features a gate-source threshold voltage range of -2.5 V to -4.5 V, and is rated for junction temperatures from -55°C to +150°C. Molding epoxies meet UL 94 V-0 flammability classification. Transient gate-source voltage withstand is ±30 V, and the maximum lead temperature for soldering is 260°C for 10 seconds. Thermal resistance from junction to case is 0.50°C/W for the TO-263 package. The device complies with international standard packages and supports space-saving, high-power-density designs.
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).
