Phase Control Thyristors, Littelfuse
Excellent uni-directional switches for phase control applications such as heating and motor speed controls. Sensitive gate SCRs are easily triggered with microamperes of current. Standard phase control SCRs are triggered with few milliamperes of current at less than 1.5V potential.
Thyristors - Littelfuse
A Thyristor is a solid-state semiconductor device with four layers of alternating N and P-type material. They act as bistable switches, conducting when their gate receives a current trigger, and continue to conduct while they are forward biased. Thyristors are synonymous to Silicon-Controlled Rectifier (SCR).

Transient Voltage Suppressors (Modules,Industrial)
Voltage surges, often referred to as spikes or transient overvoltages are typically caused by switching of fluorescent lights, fuses blowing or nearby lightning activity. The worst voltage surges are usually caused by lightning activity and can reach up to 6000V, with current surges of up to 3000A. The maximum size of the voltage and current surges depends on the location within the buildings wiring system. BS6651:1999 Annex C which was replaced in August 2008 by BS EN 62305-4:2006 is complemented by BS EN 61643-11/12 and covers location categories and provides guidance on protection of electronic equipment. For mains power systems, Types I, II and III are used. Surge protection devices not designed to fit into these...
