Avalanche Diode DL161-200X-16AS ENERGITM is general purpose stud diode, also known as DA161-200X-16. Average forward current IF(AV)200 ampere, repetitive peak forward and reverse blocking voltage VDRM/VRRM1600V. Stud avalanche are designed to convert and control DC and AC currents. "Air-cooled heatsinks O series for stud devices" for avalanche diodes cooling are also available to order.

Polarity of the diode is determined by the symbol on the body. In forward polarity, the diode base is the anode, the flexible long lead is the cathode; in reverse polarity (symbol "X" in the marking), the flexible lead is the anode, the base is the cathode.

The peculiarity of avalanche diodes in comparison with power rectifier diodes is that they withstand significant overvoltages and restore their parameters after the voltage is removed.

Air and water heatsinks are used to cool the avalanche diodes. To provide reliable thermal and electrical contact with the heatsink a tightening torque Md must be observed during assembly. For better heat dissipation of diode during assembly, heat conducting paste is used (this is a recommendation and is not a prerequisite for installation).

Features: diodes are supplied in stud with flexible lead design. Avalanche diodes are used: as rectifier and demagnetizing diodes; to prevent the damaging effects of switching overvoltages; in low voltage rectifiers for welding and electroplating equipment; in uncontrolled or semi-controlled rectifier bridges; in industrial and transport generators

Avalanche Diodes AS ENERGITM have the following features: low static and dynamic losses, wide values of VDRM/VRRM, extensive experience of using the devices in various industries, range of voltages from 100 to 9000 V and amperages from 10 to 15000 A, high resistance to thermal and electric cycling, natural or forced air cooling.

Heat sinks for power stud diodes:

Heat sinks (radiators) are used for cooling of power semiconductor devices in stud 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 heatsinks: "Air-cooled heatsinks for stud devices".


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.

Is It need to apply vaselin or thermal past at Thyristor surfaces then attach to radiator/current leading parts?

When assembling thyristors, diodes with heat sinks, it is recommended to lubricate the contact surfaces with a thin layer of heat conducting paste to improve the heat transfer parameters. But this is not a prerequisite for assembly.
