Thyristor BT151S-650R with reverse voltage 650 V, direct current 7.5 A, 2 mA gate current and DPAK housing.

The thyristor is a major electronic component in high-voltage electrical engineering. It is a semiconductor element with a non-linear volt-ampere characteristic with two stable states of low and high conductivity. Due to the absence of switching parts, the triosters have high performance and long life and are therefore widely used as a substitute for various contactors and relays in starting circuits, regulators, rectifiers, inverters, automatic devices and more.
