DESCRIPTION

N-P-N silicon planar epitaxial transistor primarily intended for use in linear u.h.f. amplifiers for television transmitters and transposers.

The excellent d.c. dissipation properties for class-A operation are obtained by means of diffused emitter ballasting resistors and a multi-base structure, providing an optimum temperature profile on the crystal area. The combination of optimum thermal design and the application of gold sandwich metallization realizes excellent reliability properties.

The transistor has a 1⁄4 capstan envelope with ceramic cap.
