The 12V Zener Diode is a semiconductor device that maintains a stable 12-volt reference voltage when reverse biased. It is widely used in shunt regulators, over-voltage protection circuits, voltage reference circuits, and signal clipping applications. With a breakdown voltage of 12V, this Zener ensures safe operation of microcontrollers, sensors, LED drivers, battery chargers, and industrial power systems. Available in DO-35 / DO-41 axial packages as well as SMD versions, 12V Zener diodes are reliable, cost-effective, and easy to integrate into circuits. NeoGiga India supplies genuine, RoHS-compliant 12V Zener diodes in bulk packs, assortment kits, and institutional supply, trusted by students, startups, OEMs, and industries across India.
