What is a Power Thyristor?
A thyristor, or silicon controlled rectifier (SCR), is a solid-state component which is used in order to switch and control electric current flow. Due to the robustness of thyristors, they are often used in high current flow applications. A thyristors will start to conduct current when it receives a certain voltage on its gate terminal and continue to conduct current even after that voltage is removed from the gate terminal. Thyristors are therefore used as current controllers due to these characteristics as well as a wide power rating range.
Types of Power Thyristors
There are many different kinds of power thyristors. At Future Electronics we stock many of the most common types categorized by On-State Voltage, Off-State Voltage, On State Current, Off-State Current, Maximum Gate Trigger Current, Packaging Type and Maximum On-state RMS 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 1.55 V and 1.6 V. We also carry power thyristors with On-State Voltage as high as 1.75 kV. Off-State Voltage can be between 30 V and 2200 V, with 600 V being the most common value.
