| TN2425TG Low Threshold Dual N-Channel Enhancement-Mode Vertical DMOS FET Features Dual N-channel device Low threshold - 2.0V max. High input impedance Low input capacitance - 200pF Fast switching speeds Low caps ON resistance Free from secondary breakdown Low input and output leakage General Description The Supertex TN2425TG is a dual low threshold enhancement mode (normally off) transistor utilizing a vertical DMOS structure and Supertex's well proven silicon-gate manufacturing process. This combination produces a device with the power handling capabilities of bipolar transistors, 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. 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 Medical ultrasound pulsers Analog switches General purpose line drivers Telecom switches Ordering Information Device TN2425TG Package Option 8-Lead SOIC (Narrow Body) TN2425TG BVDSS/BVDGS 250V RDS(ON) (max) 3.5 VGS(th) (max) 2.0V ID(ON) (min) 1.8A Absolute Maximum Ratings Parameter Drain to source voltage Drain to gate voltage Gate to source voltage Thermal resistance, Junction to drain lead Operating and storage temperature Soldering temperature1 Value BVDSS BVDGS 20V 50C/W Pin Configuration S1 1 8 D1 G1 2 7 D1 S2 -55C to +150C +300C 3 6 D2 G2 4 5 D2 Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these conditions is not implied. Continuous operation of the device at the absolute rating level may affect device reliability. All voltages are referenced to device ground. Note 1.
