"Air-cooled heatsinks O series for stud devices", for diode cooling are also available to order.

Fast Recovery Diodes ASDS AS ENERGITM are a replacement, analog, alternative semiconductor devices for Fast Recovery Diodes Stud Type Vishay Semiconductors.

Features: optimised for line frequency; low on-state losses; low reverse recovery time; high switching speed; high reverse voltage and high current handling capabilities.

The fast recovery diodes converting DC and AC currents up to 85A in circuits with voltages up to 1000V. Their main applications are for DC-DC converters and inverters, high-frequency rectifiers, switching power supplies.

The peculiarity of diodes is their fast recovery (short reverse recovery time trr and small recovery charge) and application at high frequencies. Diodes have a high current-carrying capacity at high frequencies.

The diode has an industry standard stud design making it easy to integrate the device into existing equipment. The polarity of the diode (anode, cathode) is determined by the icon on the case. The technical specifications, part numbering guide, datashets for diodes are listed below.

Rectifier Diodes AS ENERGITM have the following features: low static and dynamic losses, high values of VRSM/VRRM, extensive experience of using the devices in various industries, range of voltages from 100 to 9000 V and amperages from 100 to 15000 A, high resistance to thermal and electric cycling.

Our company provides a quality guarantee for rectifier 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.
