SIMPLORER 6.0 — Manual 163
>>Basics>Circuit>Spice-Compatible Models>Field-Effect Transistors
The Spice-compatible MESFET N-channel and MESFET P-channel models simulate the electrical
and thermal behavior of a JFET using SPICE3 parameters and equations. Electrical
characteristics and the temperature dependence of MESFET behavior are calculated according
to user-defined device parameters.

� «Value»
Click the «Value» field of the corresponding parameter to define a value. Common parameter
types. Enter a numerical value, a variable, or an expression. The parameters can be set only
at the beginning of a simulation.
Look the parameter meaning up in the info lines of the parameter table (online help).
«Name»«Default»«Unit»«Description»
Displays the parameter names and their corresponding unit, default value, and description.
You cannot make changes in these fields. If you want to add user-specific information to a
parameter, use the «Info» field in the component output dialog.
