📝 Component Overview
The BUT135A is likely a thyristor component used for controlling high currents and voltages in various applications. Thyristors are semiconductor devices that can be used as switches or rectifiers. They have three layers and can be triggered into conduction by a small signal. Once triggered, the device will continue to conduct until the current through it drops below a certain threshold. Thyristors are commonly used in power supplies, motor control circuits, and lighting systems.
