BF257
BF258-BF259
HIGH VOLTAGE VIDEO AMPLIFIERS
DESCRIPTION
The BF257, BF258 and BF259 are silicon planar
epitaxial NPN transistors in Jedec TO-39 metal
case. They are particularly designed for videooutput
stages in CTV and MTV sets, class A audio output
stages and drivers for horizontal deflection circuits.
