Model the Gate Charge, Transient, and Diode Reverse Recovery
Characteristics
DESCRIPTION
The attached spice model describes the typical electrical
characteristics of the p-channel vertical DMOS. The subcircuit
model is extracted and optimized over the
−55
to 125°C
temperature ranges under the pulsed 0-V to 5-V 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 C
gd
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.
SUBCIRCUIT MODEL SCHEMATIC
This document is intended as a SPICE modeling guideline and does not constitute a commercial product data sheet. Designers should refer to the appropriate
data sheet of the same number for guaranteed specification limits.
