Unlike the more common enhancement-mode MOSFETs that are normally-off, depletion-mode devices conduct current at VGS=0V and require a negative gate-source voltage to turn off. This normally-on characteristic makes the IXTT10N100D2 ideal for applications where the circuit must remain active without gate drive, such as start-up circuits, current regulators, active loads, and normally-closed solid-state relays. The device features a maximum RDS(on) of 1.5 Ohm at VGS=10V, 200 nC typical gate charge, and an exceptionally low thermal resistance of 0.18 K\/W (junction-to-case) enabling 695W power dissipation with adequate heatsinking. The D2 series represents the second-generation depletion-mode technology from IXYS, offering improved performance over the original D series. The TO-268AA package provides a large mounting tab for direct heatsink attachment in surface-mount applications.","working_principle":"The IXTT10N100D2 operates as an N-Channel depletion-mode MOSFET, which differs fundamentally from the more common enhancement-mode type. In a depletion-mode device, a conductive channel exists between drain and source at VGS=0V due to the implanted channel region in the silicon. The device is normally-on, meaning current flows from drain to source with zero gate voltage applied. To turn the device off, a negative gate-source voltage (VGS) must be applied that depletes the channel of charge carriers. The gate-source cutoff voltage (VGS(off)) is specified as a maximum of -4.5V, meaning the device turns off when VGS is more negative than this threshold. In linear operation, the drain current is controlled by the gate voltage between VGS(off) and 0V, making depletion-mode MOSFETs natural current sources or active loads. The IXYS planar MOSFET structure provides a linear mode tolerant design, meaning the device can safely operate in the saturation region (simultaneous high VDS and ID) without the thermal runaway issues that plague some enhancement-mode MOSFETs in linear mode. The internal body diode between source and drain provides reverse conduction capability, and the device can block up to 1000V in the off state.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>Gate<\/td><td>Input<\/td><td>Gate terminal; controls channel conduction.
