If transistors with max. 4 mm lead length are fixed on PCBs with a min. 10 mm x 10 mm large copper area for the collector terminal, RthJA = 125 K/W and thus Ptot max = 1 W at TA = 25 C. Mounted on Al heat sink 15 mm x 25 mm x 0.5 mm. Semiconductor Group 1 5.91 BC 875 ... BC 879 Electrical Characteristics at TA = 25 C, unless otherwise specified. Parameter Symbol min.
