Rectifier Diode D243-1000 AS ENERGITM is general purpose disc diode. This is a power p-n junction diode designed for converting DC and AC currents up to 1000A with frequency up to 500Hz in circuits with voltages up to 2000V – 2600V (voltage class from 20 to 26). Diode dimensions ØDxØdxH – 60x37x20 mm (outer case diameter X contact surface diameter X case height), weight – 240 g.

The anode and cathode of the diode (polarity) are determined by the symbol on the case. Diodes are in a industry-standard ceramic press pack disc (capsule, tablet) housing. This rectifier diode can be an alternative product, replacement, analog, equivalent for other types diodes 850A, 900A, 950A, 990A, 1000 amp in a disk type package.

For cooling during the operation of power semiconductor diodes 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 diode case (indicated in the parameter table) must be provided.

Semiconductor diodes 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 diodes:

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 coolers: "Water Heatsink SS series", "Air Heatsink SF series", and also "Air-heatsink" and "Water-heatsink".
