SPICE Device Model Si2343CDS
Vishay Siliconix
P-Channel 30 V (D-S) MOSFET
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 °C
to + 125 °C temperature ranges under the pulsed 0 V to 10 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.
CHARACTERISTICS
• P-Channel Vertical DMOS
• Macro Model (Subcircuit Model)
• Level 3 MOS
• Apply for both Linear and Switching Application
• Accurate over the - 55 °C to + 125 °C Temperature Range
• Model the Gate Charge, Transient, and Diode Reverse
Recovery Characteristics
