A silicon-controlled switch (SCS) behaves nearly the same way as an SCR; but there are a few differences. Unlike an SCR, an SCS switches off when a positive voltage/input current is applied to another anode gate lead. Unlike an SCR, an SCS can be triggered into conduction when a negative voltage/output current is applied to that same lead.
The TO-66 package is made entirely of metal and is commonly used by silicon controlled rectifiers and power transistors. [2] In Europe, a similar package with slightly different dimensions (SOT-9) was popularly used, e.g., by the complementary germanium power transistors AD161/AD162.
Both selenium and copper oxide rectifiers have somewhat better tolerance of momentary voltage transients than silicon rectifiers. Typically these rectifiers were made up of stacks of metal plates or washers, held together by a central bolt, with the number of stacks determined by voltage; each cell was rated for about 20 V.
The first letter represents the semiconductor material used for the component (A = germanium and B = silicon) and the second letter represents the general function of the part (for diodes, A = low-power/signal, B = variable capacitance, X = multiplier, Y = rectifier and Z = voltage reference); for example:
Up to 3000 amperes and 5000 volts in a single silicon device. High voltage requires multiple series silicon devices. Silicon-controlled rectifier (SCR) This semi-controlled device turns on when a gate pulse is present and the anode is positive compared to the cathode. When a gate pulse is present, the device operates like a standard diode.

Gregory Peck played beloved father Atticus Finch in To Kill a Mockingbird, and according to his children, the Oscar-winning actor wasn’t too far off the mark in real life. “Of all the children ...
A thyristor (/ θ aɪ ˈ r ɪ s t ər /, from a combination of Greek language θύρα, meaning "door" or "valve", and transistor [1]) is a solid-state semiconductor device which can be thought of as being a highly robust and switchable diode, allowing the passage of current in one direction but not the other, often under control of a gate electrode, that is used in high power applications ...
