To turn on a thyristor, a low voltage, short duration pulse is applied to the gate (typically 4V, 100µs). Once the thyristor is turned-on, the gate loses control and the thyristor will only turn off when the load current falls virtually to zero, or the thyristor is reverse biased.

Thyristor to turn-“ON” we need to inject a small trigger pulse of current (not a continuous current) into the Gate, (G) terminal when the thyristor is in its forward direction, that is the Anode, (A) is positive with respect to the Cathode, (K), for regenerative latching to occur.

When An SCR conducts appreciable current?
And SCR will conduct appreciable current when it is gated "on" and thus "told" to conduct. A silicon controlled rectifier(SCR) is an electronically controlled DC switch, and the gate is the terminal to which the control voltage is applied. Use the link below to learn more.
How do you use a thyristor as a diode?
A thyristor, also known as a silicon controlled rectifier, is a diode that can be turned on by application of a small gate voltage.
What are the advantages of a silicon-controlled rectifier?
SILICON CONTROLLED RECTIFIER APPLICATIONS i) Speed control for motors ii) Temperature control for electric hot plate iii) Dimmer switch for domestic lighting iv) Dimmer control for stage lighting.
Is BT169 a npn or pnp transistor?
BT169 is neither an NPN nor a PNP transistor. BT169 is a thyristor, otherwise known as a silicon controlled rectifier.
The conclusion of a silicon controlled rectifier?

What is SCR in drilling rig?
It is a silicon-controlled rectifier, converting AC to DC for use in drawworks, mud pumps, etc.:silicon-controlled-rectifier
Why Silicon Controlled Rectifier is called current controlled device?
Because it is controlled by the gate current
Why it is named silicon controlled rectifier?
i got no idea mate
On a silicon-controlled rectifier which wire is the anode and which the cathode?
Anode is positive, cathode is negative
Difference between silicon-controlled rectifier and diode?
silicon controlled rectifier is a 3 terminal 4 layer device which has 2 consecutive P N junctions here the three terminals called anode, cathode and gate gate controls the conduction of the scr but diode just conducts in forward bias and blocks in reverse bias
When an SCR turns on it acts like n?
An SCR (Silicon Controlled Rectifier) acts like a switch when turned on. It can also be used as a rectifier.
What is the cost of silicon controlled rectifier?
A: A hockey pack package $300 a TO18 package $0.10
Why silicon controlled rectifier doesn't work in reverse biased condition?
Because when reverse biased it behaves like any other rectifier/diode.
Is a silicon controlled rectifier used for computers?
I have seen them used, yes. However it is rather rare now.
What is designed to use a small current to control a large current?
A silicon controlled rectifier falls into this category.
What is a silicon-controlled rectifier?
A silicon-controlled rectifier is a semiconductor device that is used as a switch in an electrical circuit. It's a solid state direct current (DC) electronic switch. There is a ton of information including a detailed description of the SCR and a list of applications at the Wikipedia article. A link is posted below.
