SPICE Device Model Si2324DS Vishay Siliconix N-Channel 100 V (D-S) MOSFET DESCRIPTION CHARACTERISTICS 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 °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 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. • N-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 SUBCIRCUIT MODEL SCHEMATIC D CGD R1 3 M2 Gy G RG – + ETCV Gx CGS DBD M1 S Note • This document is intended as a SPICE modeling guideline and does not constitute a commercial product datasheet. Designers should refer to the appropriate datasheet of the same number for guaranteed specification limits. Document Number: 63245 S11-1189-Rev.
