Thyristor module MT3-115-36-F

Used to convert DC and AC currents up to 115 ampere, with a frequency of up to 500 Hz on circuits with voltages up to 3600 volt (36 class). Thyristor modules MT3-115-36-F are in a standard package F: base dimensions 34x94 mm, housing height – 30 mm, weight – 0.35 kg. Two-position module is a monolithic construction of two semiconductor thyristors: type thyristor-thyristor. Module connection diagram MT3-115-36-F – half-bridge. Series (ratings) of thyristor modules: MT3-115-30-F (115A 3000V), MT3-115-32-F (115A 3200V), MT3-115-34-F (115A 3400V), MT3-115-36-F (115A 3600V). Main terminals are at the top of the case and are numbered 1, 2, 3; Control terminals are marked on the diagram as G1, G2; Additional cathodes are marked on the diagram as K1, K2; High thermal cyclic resistance and reliable operation of low-frequency thyristor modules MT3-115-36-F when switching high currents is achieved due to their design features and stable parameters of galvanic isolation. The MT3-115-36-F thyristor modules have a clamp-on design that provides easy mounting and good contact with the cooler for heat dissipation. Several modules can be mounted on one cooler without additional insulation, which significantly reduces the overall dimensions of the assembly. Between the module and the heat sink (heat sink) it is recommended to use a thermally conductive substrate lubricated with thermal paste. The two-position modules have different wiring diagrams (electrical circuit diagrams): MT3 – half-bridge; MT4 – common cathode circuit; MT5 – common anode circuit.
