| TP2435 Low Threshold P-Channel Enhancement-Mode Vertical DMOS FETs Ordering Information BVDSS / BVDGS -350V * ** Die in wafer form. RDS(ON) (max) 15 VGS(th) (max) -2.4V ID(ON) (min) -800mA Order Number / Package TO-243AA* TP2435N8 Die** TP2435NW Same as SOT-89. Product supplied on 2000 piece carrier tape reels. Product marking for TO-243AA: TP4S where = 2-week alpha date code Features Low threshold High input impedance Low input capacitance Fast switching speeds Free from secondary breakdown Low input and output leakage Complementary N- and P-channel devices Low Threshold DMOS Technology These low threshold enhancement-mode (normally-off) power transistors utilize a vertical DMOS structure and Supertex's wellproven 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.
