The IXTU01N100D is a normally-on N-channel depletion mode MOSFET in a TO-251 package, rated for 1000 V drain-source voltage and 400 mA continuous drain current. It has a maximum RDS(on) of 80 Ω at 25 °C and a power dissipation of 25 W. The device features a low RDS(on), fast switching speed, and a rugged polysilicon gate structure. Operating junction temperature ranges from -55 °C to 150 °C. The molded epoxy meets UL 94 V-0 flammability rating. The TO-251 package has a weight of 0.40 g and dimensions consistent with industry-standard mounting. Thermal resistance from junction to case is 1.6 °C/W. The gate-source voltage is rated for continuous ±20 V and transient ±30 V. Applications include level shifting, triggers, solid state relays, and current regulators.
Depletion mode MOSFETs, unlike the regular enhancement type MOSFETs, require a negative gate bias to turn off. Consequently they remain on at or above zero gate bias voltage but otherwise have similar MOSFET like characteristics. They are suitable for level shifting, solid state relays, current regulators, and active loads.
