the G pole is connected with the positive pole of a diode D1, and the negative pole of the diode D1 is connected with the B pole of a triode T2;
the C electrode of the triode T1 is respectively connected with the anode of the diode D2 and one end of the resistor R4; the other end of the resistor R4 is connected with the K pole;
the cathode of the diode D2 is connected to the B pole of the transistor T2.
Preferably, the resistor R1 is further included, one end of the resistor R1 is connected with the cathode of the diode D1, and the other end of the resistor R1 is connected with the K pole.
Preferably, the transistor T1 is PNP type and the transistor T2 is NPN type.
Wherein, the A pole is the anode of the device, the K pole is the cathode of the device, and the G pole is the control pole of the device. The functions of the A pole, the K pole and the G pole correspond to the functions of the A pole, the K pole and the G pole of the existing silicon controlled rectifier.
The utility model adopts triode T1 and triode T2 to combine to realize the controllable silicon. For example, a high-brightness light-emitting diode can keep brightness by a current of a few microamps, and the power-saving function can be realized by using the silicon controlled rectifier simulation device, and a small battery can be used for a plurality of years.
When the device is used, the G pole is electrified, then current flows through the diode D1, and then the current is divided into two paths, one path passes through the triode T2 and the resistor R3 to the K pole, and the other path passes through the resistor R1 to the K pole. Meanwhile, the pole A is conducted, the current is divided into two paths from the pole A through the triode T1, and one path passes through the resistor R2, the triode T2 and the resistor R3 to the pole K; the second path is divided into two paths, wherein one current enters the resistor R1 and the triode T2 through the diode D2, the current passing through the resistor R1 enters the K pole, the current passing through the triode T2 passes through the resistor R3 to the K pole, and the second current passes through the resistor R4 to the K pole. After the G pole is turned off, the A pole is not turned off and is still in a conducting state,
the resistance value of the resistor R1 is larger, when larger interference exists in the outside, the triode T2 is easily conducted, at the moment, current passes through the resistor R1 to the K pole, the voltage at two ends of the resistor R1 is smaller, and the triode T2 cannot be conducted. The resistance value of the resistor R1 is not particularly limited, so long as the function of the resistor R1 can be realized.
Resistor R2 serves to limit the magnitude of the current in the branch. Resistor R4 functions to control the magnitude of the current flowing through transistor T2.
