what will happen when a SCR is heated.will it turn on the SCR at a value much lower than breakdown voltage?

An SCR or Silicon Controlled Rectifier is a type of semiconductor device used for controlling high-power electrical circuits.
When a small current is applied to the gate terminal of an SCR, it allows a larger current to flow from the anode to the cathode, similar to a switch. The SCR will continue to conduct until the current falls below a certain threshold.
When an SCR is heated, its electrical resistance decreases, allowing more current to flow through it. This can cause the SCR to heat up even further, creating a positive feedback loop and potentially damaging the device.
Yes, an SCR can be damaged by overheating. If the SCR is not properly cooled or if it experiences a surge in current, it can overheat and lead to failure of the device.
To prevent overheating, proper heat dissipation techniques should be used, such as attaching a heat sink or using a fan. It is also important to ensure that the SCR is not exposed to excessive currents or voltage spikes.
