Switching Thyristor Voltage Suppressors
for Circuit Protection

A Thyristor is any semiconductor switch with a bi-stable action depending on p-n-p-n regenerative feedback. Thyristors are normally two- or three-terminal devices for either unidirectional or bi-directional circuit configurations.

Thyristors can have many forms, but they all have certain commonalities:
They are solid state switches that are normally open circuits (very high impedance)
They are capable of withstanding rated blocking/off-state voltage until triggered to on state
When triggered to on state, they become a low-impedance current path until principle current either stops or drops below a minimum holding level
After a Thyristor is triggered to on-state condition, the trigger current can be removed without turning off the device
Thyristors are used to control the flow of electrical currents in applications including:
Home appliances - lighting, heating, temperature control, alarm activation, fan speed
Electrical tools - for controlled actions such as motor speed, stapling event, battery charging
Outdoor equipment - water sprinklers, gas engine ignition, electronic displays, area lighting, sports equipment, physical fitness
