Philips Semiconductors. Product speciﬁcation. NPN general purpose ...Philips customers using or selling these products for use in such applications do so at their own risk and agree to fully indemnify Philips for any damages resulting from such improper use or sale. Data Sheet Status Objective speciﬁcation This data sheet contains target or goal speciﬁcations for product development.Thus the BC548 (or BC546 to 550) is a valid substitute in any circuit designed for the older BC108 (or BC148), which includes many Mullard and Philips published designs.  As of 2016, the BC548 is principally produced by ON Semiconductor and Fairchild Semiconductor. Pinout and specifications VBEsat decreases by about 1.7 mV/K with increasing temperature. datasheet search, datasheets, Datasheet search site for Electronic Components and Semiconductors, integrated circuits, diodes and other semiconductors.
