BC549C Spice Model

Did you look for models of BC546 through BC549? For example, my spice library only has six of the 10 possibilities in the series. Also, a raft of other manufacturers make these parts.

The SPICE I use has the BC546B as an alias for the BC549, here is the model:

*From Philips SC04 "Small signal transistors 1991"

• Base spreading parameters (RB,IRB,RBM) estimated. TR derived using BCY58 data .model BC546B npn ( IS=7.59E-15 VAF=73.4 BF=480 IKF=0.0962 NE=1.2665

• ISE=3.278E-15 IKR=0.03 ISC=2.00E-13 NC=1.2 NR=1 BR=5 RC=0.25 CJC=6.33E-12

** Groper alert !!

** The BC549C differs from other BC549s only in that particular devices have been selected so the Hfe is within the range of 420 to 800.
