| TN2535 Low Threshold New Product N-Channel Enhancement-Mode Vertical DMOS FETs Ordering Information BVDSS / BVDGS 350V * Same as SOT-89. RDS(ON) (max) 10 VGS(th) (max) 2.0V ID(ON) (min) 1.0A Order Number / Package TO-243AA* TN2535N8 Product supplied on 2000 piece carrier tape reels. Features Low threshold High input impedance Low input capacitance -- 125pF max. Fast switching speeds Low on resistance Free from secondary breakdown Low input and output leakage Product marking for TO-243AA TN5S Where = 2-week alpha date code Low Threshold DMOS Technology These low threshold enhancement-mode (normally-off) transistors utilize a 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 very low threshold voltage, high breakdown voltage, high input impedance, low input capacitance, and fast switching speeds are desired. Applications Logic level interfaces - ideal for TTL and CMOS Solid state relays Battery operated systems Photo voltaic drives Analog switches General purpose line drivers Telecom switches Package Option Absolute Maximum Ratings Drain-to-Source Voltage Drain-to-Gate Voltage Gate-to-Source Voltage Operating and Storage Temperature Soldering Temperature* * Distance of 1.6 mm from case for 10 seconds.
