2 DESCRIPTION PINNING NPN transistor encapsulated in a 4 lead SOTA envelope with a ceramic cap. All leads are isolated from the stud. It is primarily intended for driver and final stages in MATV system amplifiers. It is also suitable for use in low power band IV and V equipment. Diffused emitter-ballasting resistors and the application of gold sandwich metallization ensure an optimum temperature profile and excellent reliability properties. The device also features high output voltage capabilities. PIN DESCRIPTION Code: / collector emitter 3 base 4 emitter lfpage 4 3 Top view MBK87 Fig. SOTA.
