PDF datasheet covering the 2N5194 transistor, 213 KB, with an RE suffix in the name that may denote a reissued or alternate vendor copy. Part of the 2N5191 to 2N5195 medium-power family, it should detail polarity, collector ratings, safe operating area, gain and thermal resistance. Technicians use these figures when replacing a failed output stage, sizing a substitute or checking that heatsinking is adequate. Verify the pin order and tab connection against the board layout before installing a new part.
