Thyristor Suppliers in Kolkata, West Bengal

Thyristor in Kolkata, West Bengal, are critical for supporting industries that require reliable power switching and automation. These semiconductor devices are widely applied in rectifiers, voltage regulators, and motor drives, enabling factories and plants to maintain efficiency and system stability. Industrial hubs in Howrah, Dankuni, and Kharagpur also depend on thyristors to power their heavy engineering, process industries, and energy systems.

In Kolkata, Thyristors are used across multiple industries including steel, power generation, and automation. Power plants integrate them into rectifiers and voltage regulators. Electronics and testing facilities adopt fast-switching variants for precision circuits. Heavy industries use them for motor drives, welding systems, and furnace controls, ensuring long-term durability and stable performance.

Several categories of Thyristors are available to meet industrial requirements. Phase-controlled devices are commonly applied in rectifiers and motor drives. Gate turn-off thyristors are suitable for automation circuits where controlled switching is required. Light-triggered types are preferred in sensitive electronics where precise contactless activation is needed. This variety allows industries in Kolkata to select devices tailored to their applications.

Leading global brands supply Thyristors to Kolkata’s industries. Manufacturers such as Siemens, ABB, Fuji Electric, Toshiba, Infineon, Mitsubishi Electric, Vishay, STMicroelectronics, Hitachi, Autonics, General Electric (GE), and Semikron provide modules designed with higher current ratings, advanced heat management, and durable packaging for modern industrial conditions.

When sourcing a Thyristor, industries in Kolkata consider specifications that determine efficiency and reliability. Key parameters include:

• Repetitive Peak Off-State Voltage (V_DRM, V_RRM): Blocking capacity from 400V to 6.5kV, depending on application.
• Average On-State Current (I_T(AV)): Continuous current capacity from a few amps to several kiloamperes.
• Surge Current (I_TSM): Tolerance for short surges, often 10–20 times the rated current.
• Gate Trigger Current & Voltage: Minimum input required for activation, usually in the milliamp range.
• Holding & Latching Current: Defines the current required to maintain conduction once triggered.
• Turn-Off Time (t_q): Recovery period before the thyristor regains blocking capability.
• Thermal Limits: Junction temperature up to 150°C with optimized resistance for effective heat dissipation.

A typical industrial Thyristor module used in Kolkata may feature a blocking voltage of 1800V, continuous current rating of 500A, surge capacity up to 10kA, and a junction temperature rating of 140°C. These parameters make it suitable for demanding environments such as rectifiers, high-power motor drives, and furnace control systems.

Applications of Thyristors in Kolkata cover a wide range of sectors. Heavy engineering in Howrah uses them in motor drives and power systems. Manufacturing facilities in Dankuni apply them in rectifiers and process automation. Electronics and testing facilities in Kharagpur use fast-switching thyristors for advanced automation systems.
