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.

Power Thyristors from Future Electronics

Future Electronics has a full power thyristor selection from several manufacturers when looking for high power thyristors for a triac thyristor circuit or for any circuits or applications that may require a power thyristor. Simply choose from the power thyristor technical attributes below and your search results will quickly be narrowed in order to match your specific power thyristor application needs.

If you have a preferred brand, we deal with several manufacturers such as Littelfuse, ON Semiconductor and STMicroelectronics, among other manufacturers.

Applications for Power Thyristors:

Power thyristors are used in applications where high voltages and currents are present. They are generally used in order to control alternating currents. Power thyristors can also be used as the control elements for phase fired controllers.

Choosing the Right Power Thyristor:

When you are looking for the right power thyristors, with the FutureElectronics.com parametric search, you can filter the results by various attributes: by On-State Voltage (800 mV, 1.55 V, 1.6 V), Off-State Voltage (30 V, 400 V, 600 V, 800 V,…) and Maximum Gate Trigger Current (from 1 µA to 150 A) to name a few.

You will be able to find the right high power thyristors for your triac thyristor circuits or for applications requiring a power thyristor circuit.

Power Thyristors in Production Ready Packaging or R&D Quantities

If the quantity of power thyristors that you require is less than a full reel, we offer customers many of our power thyristor products in tube or individual quantities that will help you avoid unneeded surplus.

In addition, Future Electronics offers clients a unique bonded inventory program that is designed to eliminate potential problems that could arise from an unpredictable supply of products containing raw metals and products with long or erratic lead times. Talk with your nearest Future Electronics branch and find out more on how you can avoid possible shortages.
