ABB 5SHY3545L0005 Asymmetric Integrated Gate Commutation Thyristor

ABB 5SHY3545L0005 is an Integrated Gate-Commutated Thyristor (IGCT) product and an outstanding achievement of ABB in the field of power electronics. It skillfully integrates the fast turn-off characteristic of transistors with the advantages of thyristors in withstanding high voltage and large current, and is elaborately designed for medium-high voltage, high-power power electronic application scenarios. This product can operate stably in complex and harsh power environments, providing core support for the efficient and reliable operation of power systems. It is widely used in key systems such as medium-high voltage frequency converters, static var compensators, and high-voltage direct current transmission. In fields like industrial production and power transmission, it helps achieve precise power conversion and control, strongly promoting the development of related industries towards intelligence and high efficiency.

In the forward blocking state, 5SHY3545L0005 withstands a forward anode voltage. Since no trigger signal is received at the gate, the thyristor is in the off state with only a weak leakage current. When a suitable forward trigger pulse is applied to the gate, the injection of gate current causes the internal PNP and NPN transistors of the thyristor to interact and enter a positive feedback state, enabling the device to turn on rapidly, with current flowing from the anode to the cathode. After turning on, as long as the anode current remains above the holding current, the thyristor will stay on even if the gate trigger signal is removed. When the anode current drops below the holding current or a reverse anode voltage is applied, the thyristor returns to the blocking state, thereby achieving precise control of the current in the circuit and meeting the operational requirements of different power systems.
