Default Is it right the Spice model of MJE182?

In all Spice models of MJE182 that i have download from On Semi site (PSpice, Saber, Spice2, Spice3) its parameter "Saturation Current" is given as "IS = 1e-17". When i put this value in the corresponding box of parameter table of the EDSpice Simulator (EDWinXP of Visionics) that i use, is translated automatically (and correctly) in IS = 0.01 femto Amperes. This value in my eyes (i am not so expertized in Spice Simulation) seems to be very small for a transistor with Ic=3A. For example, similar NPN transistors like BD137 with Ic=1.5A has IS = 48.15 femto Amperes. And the complementary PNP MJE172 has IS = 53.76 femto Amperes.
Can you help me please?
