Bicolour LEDs (3-lead types)
3-lead bicolour LEDs are available in
common cathode and common anode
varieties. The DCA Pro supports both types.
In the same way as the 2-lead bicolour LED analysis,
each internal LED is detailed separately on the DCA Pro
screen.
The type of bicolour LED is shown
here, in this example we have a
common cathode variety.
The pinout and V
F
specs for each
internal LED are then shown.
It can be seen here that our example has
its common cathode terminal connected
to the Green test clip.
Typical values of forward voltage for LED colours are shown here:
(LED types/manufacturers will vary significantly)
