Features Advanced DMOS Technology Free from secondary breakdown 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. Low power drive requirement Ease of paralleling Low CISS and fast switching speeds Excellent thermal stability Integral Source-Drain diode Supertex 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. High input impedance and high gain Complementary N- and P-channel devices Applications Package Options Logic level interfaces – ideal for TTL and CMOS Solid state relays Battery operated systems Photo voltaic drives Drain Analog switches General purpose line drivers Telecom switches D G Absolute Maximum Ratings Drain-to-Source Voltage Gate Source BVDSS Drain-to-Gate Voltage BVDGS TO-236AB Gate-to-Source Voltage ± 20V (SOT-23) -55°C to +150°C top view Operating and Storage Temperature Soldering Temperature* D S TO-243AA (SOT-89) 300°C Note: See Package Outline section for dimensions. * Distance of 1.6 mm from case for 10 seconds. 08/30/99 Supertex Inc. does not recommend the use of its products in life support applications and will not knowingly sell its products for use in such applications unless it receives an adequate "products liability indemnification insurance agreement."
