General Description

The Supertex VN0550 is an enhancement-mode (normallyoff) transistor that 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 coeffi cient inherent in MOS devices. Characteristic of all MOS structures, this device is free from thermal runaway and thermally-induced secondary breakdown.
