    Description

    The 12V Zener Diode is a stable and reliable voltage regulation diode designed to maintain a constant 12V reference in electronic circuits. It protects sensitive components from over-voltage and is ideal for low-power regulation, signal conditioning, and clamping applications.
    Widely used in power supplies, battery chargers, DIY electronics, and microcontroller protection circuits.

    Applications

    • 12V voltage regulation

    • Over-voltage and reverse polarity protection

    • Power supply stabilizing

    • Arduino, ESP32 & sensor protection

    • Signal clamping circuits

    • DIY electronics projects

    • Battery charging circuits
