| SPICE Device Model SI8904EDB Vishay Siliconix Bi-Directional N-Channel 30-V (D-S) MOSFET CHARACTERISTICS * N-Channel Vertical DMOS * Macro Model (Subcircuit Model) * 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 is extracted and optimized over the -55 to 125C 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 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. Document Number: 72971 S-60075Rev.
