Glossary of Terms {Definition of Diode Types}
A diode is a two terminal device using a PN junction. Diodes may be made
from Silicon, Germanium, Selenium, or Gallium Arsenide. Most diodes will
be made of Silicon. Normally a forward voltage drop of 0.7 volts will be
seen with Silicon Diodes, and a forward voltage drop of 0.3 volts will be
seen with Germanium Diodes. Diode types:
Rectifier Diode: Heavy duty [high current] used to convert AC to
DC
Tunnel Diode: Has a negative resistance region. The current
through the diode increases up to a certain voltage, than with increasing
voltage the current decreases until a voltage point is reached and the
current begins to increase again
Zener Diode: Designed to conduct in the reverse [bias] direction:
with a precise breakdown voltage [Vz]
Varactor Diode: 'Varicap' or 'VVC', Voltage [dependent] variable
capacitor [varies in picofarads]
Schottky Diode: A Schottky Diode is designed with a rapid turn on and off once the
threshold voltage is reached
Light Emitting Diode: 'LED', Gives off light when energized
[forward biased]
Photodiode: Operated in reverse-bias, reverse current increases
'almost' linearly with increase in incident light
Varistor: Resistance [flow of current] changes as a function of
applied voltage voltage. A varistor may also be called a VDR [Voltage
Dependent Resistor]. Varistors will have a negative voltage coefficient
[high resistance at low voltages and a low resistance at high
voltages].
Metal Oxide Varistor: [MOV] See listing above. MOV devices are
used in parallel with the load as protection.
Transient Voltage Suppressor: 'TVS', Designed to absorb a
transient over-voltage. The device may be designed as Uni-Polar device
protecting in one direction or a Bi-Polar device protecting the circuit
in both directions. TVS manufacturers are listed on the Transient Voltage
Suppressor page [Nonlinear Resistor Manufacturers]. TVS devices are
used in parallel with the load.
Definitions by application, include:
Clamping Diode: A diode used to limit the peak voltage on a line
to a pre-determined maximum voltage.
Welding Diode: A diode with a very large forward current rating.
