Are you looking for reliable and efficient components for managing high power in industrial applications? Thyristors (SCR - Silicon Controlled Rectifiers) from the company NAINA Semiconductor LTD are solutions designed for the highest quality, durability, and stability. As one of the leading power semiconductor manufacturers in India, NAINA provides components that are the heart of advanced control systems in electronics worldwide.

In our offer, you will find a full range of NAINA thyristors – from single screw-mount components to advanced modules, ready to operate in the most demanding conditions.

Why Choose NAINA Thyristors?

NAINA thyristors stand out with key technical features that translate into the reliability and optimal efficiency of your equipment:

• Improved Glass Passivation: This ensures high reliability and exceptional stability at high temperatures (up to 125°C).
• High Surge and Rate Immunity: Thyristors feature high di/dt and dv/dt capabilities (critical rate of rise of on-state current and off-state voltage). This is crucial for device protection in dynamic operating conditions.
• Low Thermal Resistance (Rth(JC)): Low junction-to-case thermal resistance allows for more efficient heat dissipation, which directly affects longevity and operating stability.
• Durable Construction: Devices are assembled in highly reliable, hermetically sealed packages, ensuring stability even in harsh environmental conditions.

Types of NAINA Thyristors in Our Offer

We offer various thyristor configurations to meet the specific needs of every application:

1. Stud Type Thyristors (SCR with a threaded base)

Ideal for applications where mechanical strength and solid mounting are essential. They are characterized by a high capability to operate in high currents and voltages and have excellent surge protection capabilities. They are available with Metric and UNF threads.

• Current range: from 25 A to 170 A (e.g., 25NT20, 70NT160)
• Voltage range: up to 1600 V

2. Thyristor Modules (Power Modules)

They provide a compact and isolated solution that significantly simplifies the construction of more complex circuits. Modules are available in several configurations:

• Thyristor-Thyristor Modules (TT): Two thyristors in a single isolated package (e.g., 160NTT).
• Thyristor-Diode Modules (TD): A combination of a thyristor (SCR) and a diode, available in series, common anode, or common cathode configurations.
• Phase Control Capsule Type: Capsule (disk) components for use in high-power phase control systems.

Where Are NAINA Thyristors Used?

Thanks to their durability and reliability, NAINA thyristors are key components in a wide spectrum of industrial and power applications:

• Motor Control: DC and AC motor drives, systems Soft Starter (smooth starting).
• Power Electronics: Inverters (online/offline), bridge rectifiers (fully and half-controlled), battery charger circuits, and impulse power supplies.
• Welding and Heating: Industrial welders, induction heating, heat and temperature control circuits.
• Automation and Transport: Applications in vehicles, telecommunications, and as AC switches.

By choosing NAINA Semiconductor LTD thyristors, you are opting for the highest quality, stability, and advanced technical solutions. Whether you need a simple SCR component for mounting or an advanced thyristor-diode module, in our store you will find products that ensure reliable and precise power control in your devices.
