| VN0635 VN0640 N-Channel Enhancement-Mode Vertical DMOS FETs Ordering Information BVDSS / BVDGS 350V 400V MIL visual screening available RDS(ON) (max) 10 10 ID(ON) (min) 0.75A 0.75A Order Number / Package TO-92 VN0635N3 VN0640N3 Die VN0635ND VN0640ND Features s Free from secondary breakdown s Low power drive requirement s Ease of paralleling s Low CISS and fast switching speeds s Excellent thermal stability s Integral Source-Drain diode s High input impedance and high gain s Complementary N- and P-channel devices Advanced DMOS Technology These 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 high breakdown voltage, high input impedance, low input capacitance, and fast switching speeds are desired. Applications s Motor controls s Converters s Amplifiers s Switches s Power supply circuits s Drivers (relays, hammers, solenoids, lamps, memories, displays, bipolar transistors, etc.) Package Options 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.
