SEMICONDS T3349 PNP Silicon Epibase Transistors BD 434 an joa BD 436 SIEMENS AKTIENGESELLSCHAF BD 438 BD 440 BD 442 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 436, BD 437, BD 439, and BD 441, Type Ordering code ae — BD 434 62702-0202 c = fe] Z BD 434/8D 433 paired | 062702-D217 S=S—— BD 436 62702-0204 ee onal BD 436/BD 436 paired | 062702-D218 4 8D 438 62702-0213 3 BD 4380BD 437 paired | 062702-0219 Ey BD 440 062702-D281 BD 440/BD 439 paired | 62702-0284 a8 en BD 441 paired eecheaee Approx. weight 0.6 g Dimensions in mm pair P Mica washer 062902-862 Iau mens" washer or Sng Spring wesher A3 DIN1371 Q62802-B63 WIil'a 80" fea washor (ungrased) ts used, the thermal resistence increases by 8 K/W and in case of a greased one by 4 KW.
