- a unique ability
to offer very little resistance
to current flow
the forward-bias direction but maximum resistance to current flow when
reverse biased. For this reason, the PN junction is commonly used as a diode to
convert AC to DC.
PN JUNCTION'S APPLICATION - expands many different areas (from a simple
voltage protection device to an amplifying diode). Two of the most commonly
used applications for the PN junction are the SIGNAL DIODE (mixing,
detecting, and switching signals) and the RECTIFYING DIODE (converting
AC to DC).
