What is a Protection Thyristor?
A thyristor is a solid-state component used to switch and control electric current flow. Thyristors are often used in high current flow applications due to their robustness. A thyristor starts to conduct current when it receives a certain voltage on its gate terminal and continues to conduct current after that voltage is removed from the gate terminal. Because of this characteristic and a wide protection rating range, thyristors are used as current controllers. Protection thyristors are used for overvoltage protection.
Types of Protection Thyristors
There are many different kinds of protection thyristors. At Future Electronics we stock many of the most common types categorized by On State Current, Off-State Current, On-State Voltage, Off-State Voltage, Maximum Gate Trigger Current, Packaging Type and Hold Current. The parametric filters on our website can help refine your search results depending on the required specifications.
The most common values for On-State Voltage are 4 V and 8 V. We also carry protection thyristors with On-State Voltage as high as 350 V. Off-State Voltage can be between 6 V and 600 V, with 6 V, 25 V, 58 V and 275 V being the most common values.
