The 11V Zener Diode is a semiconductor device designed to maintain a stable voltage of 11 volts across its terminals when reverse-biased. Commonly used as a voltage regulator, reference, and over-voltage protector, it ensures reliable operation in power supply circuits, embedded systems, IoT devices, robotics controllers, automotive electronics, and industrial instrumentation. With its precise 11V breakdown voltage, the diode helps stabilize DC outputs, clamp voltages, and protect sensitive components from surges. Available in through-hole (DO-41) and SMD (SOD-123, SOD-323, SMA) packages, 11V Zener diodes come in different power ratings (0.25W to 5W), depending on circuit requirements. NeoGiga India provides genuine, RoHS-compliant 11V Zener diodes with bulk packs, institutional pricing, and fast nationwide delivery, serving engineers, startups, and universities.
