N-Channel 250 V (D-S) 175 °C MOSFET

SPICE Device Model SUD17N25-165

Vishay Siliconix

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 °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

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

• 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
