| SPICE Device Model SUP/SUB70N03-09P Vishay Siliconix N-Channel 30-V (D-S), 175C MOSFET PWM Optimized CHARACTERISTICS * N-Channel Vertical DMOS * Macro Model (Model Subcircuit Schematic) * Level 3 MOS * Apply for both Linear and Switching Application * Accurate over the -55 to 125C Temperature Range * Model the Gate Charge, Transient, and Diode Reverse Recovery Characteristics DESCRIPTION The attached spice model describes the typical electrical characteristics of the n-channel vertical DMOS. The subcircuit model schematic is extracted and optimized over the -55 to 125C temperature ranges under the pulsed 0-to-5V 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. 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.
