) and load resistance (R
L
) in a typical emitter follower (Test
circuit 2) having a greater load resistance (5 k
).

As shown in Graph 2, the turn-off time for load resistance of 5 k
is about 100
μ
s. Similarly, the turn-off time for load resistance
of 100 k
is 1 to 2 ms. This is also true when the load resistance is connected to the collector of the phototransistor.
Graph 3 shows the relationship between response speed (t
on
, t
off
) and load resistance (R
L
) in a typical circuit (Test circuit 3)
having collector load resistance (5 k
) with the emitter grounded.
