Thyristor Diode Module MD/T4-800-18-D AS ENERGITM in an international standard package, 800A 1800V.

Used to convert DC and AC currents up to 800 ampere, with a frequency of up to 500 Hz on circuits with voltages up to 1800 volt (18 class).

Thyristor Diode Module MD/T4-800-18-D are in a standard package D: base dimensions 77x150 mm, housing height – 84 mm, weight – 4.1 kg. Two-position module is a monolithic construction of two semiconductors thyristor and diode: type thyristor-diode.

The range of module ratings: MD/T4-800-14-D, MD/T4-800-16-D, MD/T4-800-18-D.

High thermal cyclic resistance and reliable operation of low-frequency thyristor-diode modules MD/T4-800-18-D when switching high currents is achieved due to their design features and stable parameters of galvanic isolation.

The MD/T4-800-18-D thyristor-diode module 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.

Our modules are offered in several dual and single device topologies for almost all phase control or rectifier applications.

Our company provides a quality guarantee for thyristor / diode modules of 2 years from the date of purchase. When supplying thyristor / diode modules, if necessary, we provide technical passport and certificate of conformity.
