Phase Control Thyristor T163-1000 AS ENERGITM is general purpose disc thyristor, also known as Silicon Controlled Rectifier (SCR). This is a power thyristor designed for converting and control DC and AC currents up to 1000A with frequency up to 500Hz in circuits with voltages up to 3400V – 4400V (voltage class from 34 to 44). Thyristor dimensions ØDxØdxH – 87x60x26 mm (outer case diameter X contact surface diameter X case height), weight – 700 g.

Thyristor ratings: T163-1000-34 (1000A 3400V), T163-1000-36 (1000A 3600V), T163-1000-38 (1000A 3800V), T163-1000-40 (1000A 4000V), T163-1000-42 (1000A 4200V), T163-1000-44 (1000A 4400V).

The anode and cathode of the thyristor (polarity) are determined by the symbol on the case. Thyristors are in a press pack disc (capsule, tablet) housing. This SCR thyristor can be an alternative product, replacement, analog, equivalent for other types thyristors 850A, 900A, 950A, 990A, 1000 amp in a disk package.

For cooling during the operation of power thyristors they are mounted with coolers (heat sinks). Depending on the amount of heat generated and the working conditions of the semiconductors, either natural air flow cooling or forced cooling can be used.

When assembling, the necessary clamping force Fm specific for each type of thyristor case (indicated in the parameter table) must be provided.

Thyristors SCR disc type are used in power equipment – power and control units, power regulators, converters (e.g. melting furnaces), controllers where fast switching and control of currents is necessary.

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.

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