Power Rectifier Diodes 100A – 500A Stud Type

Power Rectifier Diodes AS ENERGITM, also known as stud mount rectifier diodes, in stud design are general-purpose diodes, converting DC and AC currents to 500A at frequencies to 500 Hz in circuits with voltages to 3000V (depending on series).

Disc Type Rectifier Diodes have the following types (current): 100 A, 125 A, 160 A, 200 A, 250 A, 320 A, 400 A, 500 Ampere.

Polarity of diodes:

  • forward polarity diode: threaded base - Anode, flexible power lead - Cathode
  • reverse polarity diode: threaded base - Cathode, flexible power lead - Anode

Polarity of the diode is marked by a polarity symbol on the case. Reverse polarity diodes are indicated by an "X" in the code, e.g. "D161-320X-16". On this page are schematic diagrams and circuits of diodes with Anode and Cathode. The technical specifications, part numbering guide, polarity, dimensions and recommended coolers for diodes are listed below.

Rectifying diodes are one of the most widespread types of power switches. The diode has an industry-standard housing making it easy to integrate the device into existing equipment. The devices have a sealed ceramic housing insulating the semiconductor element from environment.

Air and water heat sinks are used to cool the thyristors. To provide reliable thermal and electrical contact with the heatsink a tightening torque Md must be observed during assembly. For better heat dissipation of thyristor during assembly, heat conducting paste is used.

Rectifier Diodes from AS Energi Global LLC have the following features: low static and dynamic losses, high values of VRRM, extensive experience of using the devices in various industries, range of voltages from 300 to 4400 V and amperages from 100 to 500 A, high resistance to thermal and electric cycling, natural or forced air cooling.

Our company provides a quality guarantee for diodes of 2 years from the date of purchase. When supplying diodes, if necessary, we provide technical passport and certificate of conformity.

Installation recommendations for stud type power rectifier diodes:

Assembling stud diode with a heatsink

The reliability of heat transfer and electrical contact between the mating surfaces of the diode and the cooler over the entire temperature range is ensured by appropriate torque.

Before assembly you should perform visual inspection (1) contact surfaces for mechanical damages and wipe (2), soaked with alcohol (toluene, gasoline, acetone).

To improve the parameters of heat transfer it is recommended to lubricate (3) a thin layer of silicone thermal conductive paste before the assembly, which is not a mandatory condition for installation.

After installation, the fasteners (nuts and washers) must be additionally secured against corrosion.


Tips and recommendations for power diodes:

The power diodes should not be operated for long periods of time at their limit load for all parameters. In this case, the safety factor is determined by the required degree of reliability of the device.

Replace a failed power diode with a diode that matches the parameters of the one being replaced.

Supercooling must be provided when operating in an environment with an elevated ambient temperature.

Periodic cleaning of power diodes and coolers to remove dust and contaminants is recommended to ensure proper heat dissipation.

Inductive current dividers (often twisted toroidal wire) should be used to equalize currents between power diodes connected in parallel. The most popular connection methods are closed circuit, common coil circuit, or power diode. The efficiency of current dividers in this case is determined by the cross section of the magnetic wire.

Prevention of voltage unbalance when power diodes are connected in series is achieved by using shunt resistors connected in parallel with each diode. Voltage equalization in transient conditions is provided by connecting capacitors in parallel to each diode.

Device under voltage

It is strictly forbidden to touch power diodes under high voltage during operation.
