Series (ratings) of diode modules: MD5-470-38-A2 (470A 3800V), MD5-470-40-A2 (470A 4000V), MD5-470-42-A2 (470A 4200V), MD5-470-44-A2 (470A 4400V).
- Main terminals are at the top of the case and are numbered 1, 2, 3;
High thermal cyclic resistance and reliable operation of low-frequency diode modules MD5-470-44-A2 when switching high currents is achieved due to their design features and stable parameters of galvanic isolation.
The MD5-470-44-A2 diode 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.
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.
The final price for thyristor / diode modules depends on the class, quantity, delivery terms, manufacturer, country of origin and form of payment.
