Dual N-Channel Enhancement-Mode Vertical DMOS FET
Features
► Dual N-channel devices ► Low threshold – 2.0V max. ► High input impedance ► Low input capacitance – 125pF max. ► Fast switching speeds ► Low on-resistance ► Free from secondary breakdown ► Low input and output leakage
General Description
This low threshold, enhancement-mode (normally-off)
transistor utilizes 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 and 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.
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
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.
