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. - Low input capacitance - Fast switching speeds - Low on-resistance - Free from secondary breakdown - Low input and output leakage ## **Applications** - Normally-on switches - Solid state relays - Converters - Linear amplifiers 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. - Constant current sources - Power supply circuits ► Telecom **Product Summary Ordering Information R I BV /BV DS(ON) DSS Part Number Package Option Packing DSX DGX (max) (min)** DN2540N3-G TO-92 1000/Bag 400V 25Ω 150mA DN2540N3-G P002 DN2540N3-G P003 **Pin Configuration** DN2540N3-G P005 TO-92 2000/Reel **DRAIN** DN2540N3-G P013 DN2540N3-G P014 **DRAIN** DN2540N5-G TO-220 50/Tube **SOURCE** ~~t~~ DN2540N8-G TO-243AA (SOT-89) 2000/Reel ~~e~~ **SOURCE** _-G denotes a lead (Pb)-free / RoHS compliant package._ **GATE** _Contact factory for Wafer / Die availablity._ **GATE DRAIN** _Devices in Wafer / Die form are lead (Pb)-free / RoHS compliant._ **TO-92 TO-220 Absolute Maximum Ratings DRAIN Parameter Value** Drain-to-source voltage BVDSX **SOURCE DRAIN** BV **GATE** |**Parameter**|**Value**| |---|---| |Drain-to-source voltage|BVDSXDSX| |Drain-to-gate voltage|BVDGX| |Gate-to-source voltage|±20V| |Operating and storage
