| DN3525 N-Channel Depletion-Mode Vertical DMOS FETs Ordering Information BVDSX / BVDGX 250V RDS(ON) (max) 6.0 IDSS (min) 300mA Order Number / Package TO-243AA* DN3525N8 Die** DN3525NW Product marking for TO-243AA: DN5C Where = 2-week alpha date code * Same as SOT-89. Products shipped on 2000 piece carrier tape reels. ** Die in wafer form. Features High input impedance Low input capacitance Fast switching speeds Low on resistance Free from secondary breakdown Low input and output leakage Advanced DMOS Technology These low threshold depletion-mode (normally-on) transistors utilize an advanced vertical DMOS structure and Supertex's well-proven silicon-gate manufacturing process. This combination produces devices 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, these devices are free from thermal runaway and thermally-induced secondary breakdown. 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. Applications Normally-on switches Solid state relays Converters Linear amplifiers Constant current sources Power supply circuits Telecom Package Options D G D S Absolute Maximum Ratings Drain-to-Source Voltage Drain-to-Gate Voltage Gate-to-Source Voltage Operating and Storage Temperature BVDSX BVDGX 20V -55C to +150C TO-243AA (SOT-89) Note: See Package Outline section for dimensions. 12/13/01 Supertex Inc. does not recommend the use of its products in life support applications and will not knowingly sell its products for use in such applications unless it receives an adequate "products liability indemnification insurance agreement."
