Thyristors in Harare Zimbabwe

We supply quality and durable Thyristors in Harare Zimbabwe. A thyristor is a solid-state semiconductor device with four layers of alternating P- and N-type materials. It acts exclusively as a bistable switch, conducting when the gate receives a current trigger, and continuing to conduct until the voltage across the device is reversed biased, or until the voltage is removed (by some other means).

There are two designs, differing in what triggers the conducting state. In a three-lead thyristor, a small current on its Gate lead controls the larger current of the Anode to Cathode path. In a two-lead thyristor, conduction begins when the potential difference between the Anode and Cathode themselves is sufficiently large (breakdown voltage).

Thyristors or silicon controlled rectifiers are sometimes known to be unusual electronics components in many ways, but they are particularly useful for controlling power circuits. As such these electronics components can be used for many power control applications where current and voltage levels are relatively high. Thyristors may also be used in lower power applications i.e. light control, as well as for power supply protection and many other applications. Thyristors are simple to use and cheap to buy, making them an ideal option for many circuits.
