Нeatsinks 

Heatsinks for disc and stud diodes and thyristors from Proton-Electrotex. The heatsink is installed using bolts and threaded holes in the heatsink baseplate. To ensure optimal heat dissipation values it is necessary to maintain even pressure through the entire surface of the heatsink with specified force.

Proton-Electrotex designs and manufactures own heatsinks for its semiconductors, allowing the company to offer efficient solutions for reliable heat removal.

Proton-Electrotex is able to select suitable heatsink model for specific operation modes on customer’s request. It is also possible to order complete, ready-to-use power semiconductors in assembly with the heatsink.
