NAINA Semiconductor

Power Devices from India

NAINA Dioden

Naina Semiconductor Ltd. (NSL) is one of the leading manufacturers of power semiconductors in India. The agile company started in 1988 in Noida, Uttar Pradesh with plastic devices such as standard recovery & fast recovery diodes in packages of DO-41, DO-27 & R-6 for various applications, especially in the field of telecom, the company has grown to new heights. Since then, the company has continuously developed into a powerful supplier of other electrical components such as power diodes, silicon controlled rectifier (SCR), Schottky diodes (hot-carrier diode), Z diodes (Zener diodes), self-rectifiers, solar diodes, triacs, power modules, fast recovery power converters, bridge rectifiers, rectifier stacks and other custom products.
