The photo gallery shows many different semiconductor devices, semiconductor chips and SCRs produced by AS ENERGITM, examples of test reports.


Heat sinks for power disc thyristors:

Heat sinks (radiators) are used for single- and double-sided cooling of power semiconductor devices in disc design.

Heat sinks of coolers are made of aluminum radiator profiles and do not require additional protective coating when used in various climatic conditions.

Air and water heat sinks for thyristor cooling are also available to order.

See for more information about heatsinks: "Air-cooled heatsinks O series for disc devices", "Air heatsink SF series", "Water heatsink SS series".
