can anyone identify this transistor? Marked H 669A. Its in a To 126 size all plastic package but a fair bit thicker, one I have not seen before. (why?) Its an NPN with lead out BCE. Its directly on the heatsink of a power amp in series with a thermistor, so is either part of the bias circuitry or temperature sense. Datasheet pdf search engine - www.datasheetcatalog.com .

This group of graphs illustrates the relationship between hfe and other “h” parameters for this series of transistors. To obtain these curves, a high−gain and a low−gain unit were selected from the 2N4401 lines, and the same units were used to develop the correspondingly numbered curves on each graph. Figure 11.
