| TN2640 TN2640 Low Threshold N-Channel Enhancement-Mode Vertical DMOS FETs Ordering Information BVDSS / BVDGS 400V RDS(ON) (max) 5.0 VGS(th) (max) 2.0V ID(ON) (min) 2.0A Order Number / Package SO-8 TN2640LG TO-92 TN2640N3 DPAK TN2640K4 Die TN2640ND MIL visual screening available. Features Low threshold -- 2.0V max. High input impedance Low input capacitance Fast switching speeds Low on resistance 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) 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 Options D (TAB) G S SGD TO-92 TO-252 (D-PAK) 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.
