Stud Avalanche Thyristor TL271-320-10AS ENERGITM is general purpose stud thyristor, also known as TA271-320-10. Average forward current ITAV320 ampere, repetitive peak forward and reverse blocking voltage VDRM/VRRM1000V. Stud thyristors are designed to convert and control DC and AC currents. "Air-cooled heatsinks O series for stud devices" for thyristor cooling are also available to order.

Air heat sinks are used to cool the avalanche 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 (this is a recommendation and is not a prerequisite for installation).

The polarity of the thyristor is determined by the icon on the case. The base of the thyristor is the Anode, the flexible power lead is the Cathode, the flexible wire exiting the base of the power lead is the auxiliary cathode, the flexible wire exiting the case is the control electrode (Gate). The technical specifications, part numbering guide, polarity, dimensions and recommended coolers for thyristors are listed below.

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.

Avalanche Thyristors 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 thyristors:

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 power stud mount thyristors:

Assembling stud thyristor with a heatsink

The reliability of heat transfer and electrical contact between the mating surfaces of the thyristor 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 thyristors:

The power thyristors 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 thyristor with a thyristor 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 thyristors 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 thyristors connected in parallel. The most popular connection methods are closed circuit, common coil circuit, or power thyristor. The efficiency of current dividers in this case is determined by the cross section of the magnetic wire.

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

Device under voltage

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