Rectifier Diode 1500A, 1600A, type D373-1600 (7000V – 8000V)
|Average forward current, IFAV||1600A|
|Voltage code, VRRM / 100||70 – 80|
Rectifier Diode D373-1600 AS ENERGITM is general purpose disc diode. This is a power p-n junction diode designed for converting DC and AC currents up to 1600A with frequency up to 500Hz in circuits with voltages up to 7000V – 8000V (voltage class from 70 to 80). 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 1450A, 1500A, 1600 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.
