In the forward-bias region the diode current increases exponentially with increase in voltage across the diode. The direction of conduction for a Zener diode is opposite to that of the arrow in the symbol, and the Zener voltage has a polarity opposite to that of a forward-biased diode. The maximum power dissipation level of a diode is equal to the product of the diode voltage and current. Light emitting diodes (LEDs) emit light under reverse-bias conditions but require 2 V to 4 V for good emission.
