Examples:

Q50A 11 26 4 20 MOD1

nc,** nb**, and ne are the collector, base, and emitter nodes, respectively. ns is the (optional) substrate node. When unspecified, ground is used. mname is the model name, area, areab, areac are the area factors (emitter, base and collector respectively), and off indicates an (optional) initial condition on the device for the dc analysis. If the area factor is omitted, a value of 1.0 is assumed.

The (optional) initial condition specification using ic=vbe,vce is intended for use with the uic option on a .tran control line, when a transient analysis is desired to start from other than the quiescent operating point. See the .ic control line description for a better way to set transient initial conditions. The (optional) temp value is the temperature where this device is to operate, and overrides the temperature specification on the .option control line. Using the dtemp option one can specify the instance's temperature relative to the circuit temperature.
