Description

BZX55C12 – 12V 0.5W Zener Diode DO-35 Axial

The BZX55C12 is a 12V, 0.5W Zener diode in a DO-35 axial package, designed for stable voltage regulation and protection. With low reverse leakage, high stability, and excellent temperature coefficient, it’s ideal for general-purpose electronics, power supplies, and reference voltage circuits.

Applications

• Voltage stabilization in low power circuits
• Over-voltage protection
• Reference voltage generation
• General electronics and hobbyist designs

How to Use

1. Connect the cathode (banded end) to the positive rail where 12V regulation is desired.
2. Connect the anode to ground or lower potential.
3. Ensure reverse bias operation — use this diode in reverse mode to regulate voltage.
4. Use a series resistor to limit current and prevent exceeding the 0.5 W rating.
5. Mount securely on the PCB; allow for heat dissipation as needed.

Why Choose BZX55C12?

The BZX55C12 offers robust performance, widely trusted construction, low leakage current, and reliable regulation. With its DO-35 axial form and 0.5 W rating, it’s well-suited for designs needing a stable 12V reference or protection without large physical size.
