DESCRIPTION
The SD1391 is a gold metallized NPN planar tran-
sistor using diffused emitter ballast resistors for
reliability and ruggedness.
The SD1391 is specifically designed as a low
power, high gain driver and can be operated in               1. Collector         3. Emitter
Class A, B or C.                                             2. Base
