General Description
The VP0550 low-threshold, Enhancement-mode
(normally-off) transistor uses a vertical DMOS structure
and a 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.
Microchip’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.
