Eplbase power darlington transistors (62.5W)
BO 643, BD 645, BD 647, and BD 649 are monolithic NPN Silicon epibase power darlington
transistors with diode and resistors in a TO 220 AB plastic package (TOP-66). The collectors
of the two transistors are electrically connected to the metallic mounting area. These
darlington transistors for AF applications are outstanding for particularly high current
gain. Together with BD 644, BO 646, BD 648, and BD 650, they are particularly suitable
for use as complementary AF push-pull output stages.
