• N-Channel Vertical DMOS
• Macro Model (Subcircuit Model)
• Level 3 MOS
The attached spice model describes the typical electrical
characteristics of the n-channel vertical DMOS.
model is extracted and optimized over the −55 to 125°C
temperature ranges under the pulsed 0-V to 4.5-V gate drive. The
saturated output impedance is best fit at the gate bias near the
threshold voltage.

SPICE Device Model Si1970DH
• Apply for both Linear and Switching Application
• Accurate over the −55 to 125°C Temperature Range
• Model the Gate Charge, Transient, and Diode Reverse Recovery
A novel gate-to-drain feedback capacitance network is used to model
the gate charge characteristics while avoiding convergence difficulties
of the switched C
to provide a best fit to the measured electrical data and are not
intended as an exact physical interpretation of the device.
