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.

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

DACPOL offers following type of thyristors:

    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 steepness of conduction current rise and short time of switching off.

Thyristors are 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 are offered in two types of housing: screw-fit and capsule shaped of various sizes. They are mounted on heat sinks adapted to the losses generated in the SCR during electric conduction. When installing thyristors, apply a thin layer of thermally conductive paste to their casing, which improves heat transfer properties to the heat sink.

Thyristors in a screw-fit casing should be screwed to the radiator so that their terminals adhere to the whole surface. Pulse thyristors are cooled by radiators adjacent to the pellet. The appropriate pressure of the radiators to the pellet is provided by a special construction buckle equipped with a pointer to control the clamping force.

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, a RC muffler, varistors and special semiconductor elements switched between the gate and the anode, e.g. BOD type, are used.
