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 diode is an unsteady semiconductor device in which the conduction or valve state depends on the bias voltage between the anode and the cathode.

Our offer includes: rectifier diodes, fast diodes, ultra-fast diodes, Schottky diodes, avalanche diodes, diodes against overvoltage, high-voltage diodes.

The diodes used in power electronics systems require protection against the effects of short circuits and overvoltages.

Only quick fuses should be used for short-circuit protection of diodes. These are specially designed fuses with current values adapted to the current size of the diodes and burning out in a very short time after the occurrence of a short circuit. To protect diodes against commutation overvoltages, RC surge suppressors should be used. The parameters of the surge suppressor elements are selected so that the overvoltage occurring at the diode is limited to its safe value.
