Characteristics
DESCRIPTION
The attached spice model describes the typical electrical
characteristics of the n-channel vertical DMOS. The subcircuit
mode is extracted and optimized over the 55 to 125°C temperature
ranges under the pulsed 0-to-10V gate drive. The saturated output
impedance is best fit at the gate bias near the threshold voltage.
A novel gate-to-drain feedback capacitance network is used to
model the gate charge characteristics while avoiding convergence
difficulties of the switched Cgd model. All model parameter values
are optimized to provide a best fit to the measured electrical data
and are not intended as an exact physical interpretation of the
device.
