VN2450 N-Channel Enhancement-Mode Vertical DMOS FETs Features General Description Free from secondary breakdown This enhancement-mode (normally-off) transistor utilizes a Low input and output leakage vertical DMOS structure and Supertexs well-proven silicon-gate Low C and fast switching speeds manufacturing process. This combination produces a device with ISS High input impedance and high gain the power handling capabilities of bipolar transistors and with the high input impedance and positive temperature coefcient inherent in MOS devices. Characteristic of all MOS structures, Applications this device is free from thermal runaway and thermally induced secondary breakdown. Motor controls Converters Supertexs vertical DMOS FETs are ideally suited to a wide range Ampliers of switching and amplifying applications where high breakdown Switches voltage, high input impedance, low input capacitance, and fast Power supply circuits switching speeds are desired.
