1791 PNP Silicon Epibase Transistors SIEMENS AKTIENGESELLSCHAF 8 Power transistors for complementary AF stages The transistors BD 434, BD 436, BD 438, BD 440 and BD 442 are PNP silicon epibase power transistors in a TO 126 plastic package (12 A 3 DIN 41869, sheet 4). The collector is electrically connected to the metallic mounting area. The transistors are particularly suitable for use in push-pull output stages, driver stages and for general AF applications. Their complementary types are the NPN transistors BD 433, BD 435, BD 437, BD 439, - 25C ) MM 4235605 0004368 3 MMSIEG 8236320 SIEMENS/ SPCL.
