Information close
Products that are marked "On Order" in the "Available Quantity" column are usually not in stock. Such products are available for purchase, however, due to their limited customer base, they usually have higher minimum quantities. DACPOL offers products that are not in stock for the following reasons: DACPOL currently has a large number of electronic components in stock and adds new products every day, however, tens of thousands of additional components and their various variants are available from our suppliers. Even though it is unreasonable to have all these products in stock due to the limited sales, we believe that it is in the best interest of our customers to make them available. Our goal is to inform customers about the maximum number of products available and enable them to make decisions based on specifications, prices, availability, required minimums and our technical advice. Please note that selecting the "In Stock" checkbox may limit the display to only products available for delivery straight from the shelf.

A thyristor is a controllable semiconductor device, which from the blocking state goes into the conduction state after giving a short control pulse to the gate of the thyristor.

Our offer includes:
  • standard thyristors
  • fast thyristors
  • asymmetric thyristors
Standard thyristors are suitable for the construction of converters operating at the frequency of 50 Hz power networks. They can be used for the construction of controlled rectifiers and power regulators as well as soft-starters.

Fast Thyristors
Fast thyristors, also called impulse thyristors, are characterized by a short switching time, high resistance to the steepness of conduction current rise, and short time of switching off. Can be used in current inverters and voltage inverters, as well as in DC drive converters and induction heating.

Asymmetric Thyristors
Asymmetric thyristors are characterized by low backward and comparable voltage, with other types of thyristors, blocking voltage. They are used primarily in traction converters of drive systems.

Thyristors – Protection
Thyristors require protection against the effects of short circuits and switching overvoltages. Only quick fuses specially designed to protect diodes and thyristors can be used for short circuit protection. To protect the thyristors against overvoltages, an RC muffler, varistors, and special semiconductor elements switched between the gate and the anode, e.g. BOD type, are used.
