h PARAMETERS

VCE = 10 Vdc, f = 1.0 kHz, TA = 25°C

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.
