Rectifier Diode D373-1250 AS ENERGITM is general purpose disc diode. This is a power p-n junction diode designed for converting DC and AC currents up to 1250A with frequency up to 500Hz in circuits with voltages up to 9000V – 100V (voltage class from 90 to 1). Diode dimensions ØDxØdxH – 107x75x35 mm (outer case diameter X contact surface diameter X case height), weight – 1300 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 1100A, 1150A, 1200A, 1250 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.

High Power Semiconductors AS ENERGITM

Our company is engaged in the manufacturer and sale of wide range of power semiconductors (power thyristors, modules, rectifier diodes, rotor and welding diodes, triacs etc.) currents up to 15000A and voltages to 9000V, and air and water heatsinks to them. You can buy semiconductors in any volumes, and when ordering large lots, the price will be lower.
We have earned the trust of customers and cooperate with companies from neighboring countries.

For questions regarding the acquisition of Power Thyristors, Diodes, Modules send an email request to:

office@asenergi.com

And we will provide you a commercial offer for delivery.
For a large number, we will provide an individual price!!!

We are open to manufacture products at our production facilities
according to your requests and technical task.


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 "Air-heatsink" and "Water-heatsink".
