Supertex inc. DN3145 N-Channel Depletion-Mode Vertical DMOS FETs Features ►► ►► ►► ►► ►► ►► General Description High input impedance Low input capacitance Fast switching speeds Low on-resistance Free from secondary breakdown Low input and output leakage The Supertex DN3145 is a depletion-mode (normally-on) transistor utilizing an advanced vertical DMOS structure and Supertex’s well-proven silicon-gate manufacturing process. This combination produces a device with the power handling capabilities of bipolar transistors and with the high input impedance and positive temperature coefficient inherent in MOS devices. Characteristic of all MOS structures, this device is free from thermal runaway and thermally-induced secondary breakdown. Applications ►► ►► ►► ►► ►► ►► Normally-on switches Solid state relays Converters Constant current sources Power supply circuits Telecom Ordering Information Part Number DN3145N8-G Package Option TO-243AA (SOT-89) Supertex’s vertical DMOS FETs are ideally suited to a wide range of switching and amplifying applications where high breakdown voltage, high input impedance, low input capacitance, and fast switching speeds are desired. Product Summary Packing 2000/Reel BVDSX/BVDGX 450V -G denotes a lead (Pb)-free / RoHS compliant package. Contact factory for Wafer / Die availablity. Devices in Wafer / Die form are lead (Pb)-free / RoHS compliant. Parameter Value Drain-to-source voltage BVDSX Drain-to-gate voltage BVDGX Gate-to-source voltage ±20V Operating and storage temperature -55OC to +150OC Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these conditions is not implied. Continuous operation of the device at the absolute rating level may affect device reliability. All voltages are referenced to device ground. Package TO-243AA (SOT-89) θja 133OC/W‡ Notes: ‡ Mounted on FR4 board, 25mm x 25mm x 1.57mm.
