SPICE Device Model SUM110P04-05 Vishay Siliconix P-Channel 40-V (D-S) MOSFET CHARACTERISTICS • P-Channel Vertical DMOS • Macro Model (Subcircuit Model) • Level 3 MOS • 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 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 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 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.
