Glossary of Terms
Anode- An SCR terminal, positive in respect to the gate and thecathode when conducting.
Cathode-An SCR terminal, negative in respect to the anode whenconducting.
Discrete Device- An individual electrical component packaged orunpackaged, such as a resistor, capacitor, transistor, diode, etc.
Diode-A two terminal semiconductor which allows electric current
to flow easily in one direction but not in the other.
Heat sink- A material with good heat conducting or dissipatingproperties.

Rectifier - Same as diode. Also used to describe equipment thatconverts AC to DC.
Trigger - To turn on an SCR by utilizing its gate terminal.
Thyristor -A term for the general class of semiconductor deviceswhich includes SCRs, triacs, alternistors, etc.
SCR - Silicon Controlled Rectifier. A three terminalsemiconductor manufactured from silicon that blocks current flow
in one direction, can be switched from blocking to conduction inthe other direction.
