BZX84C/2BZX84C SMD Planar Zener Diodes

Diotec Semiconductor BZX84C and 2BZX84C SMD Planar Zener Diodes are silicon planar devices designed for surface‑mount, low‑power voltage control applications. Housed in a compact SOT‑23 package, the diodes are optimized for high‑density PCB layouts and automated assembly processes. The BZX84C and 2BZX84C devices offer a wide range of Zener voltages (2.2V to 50V) with a standard E24 tolerance of about ±5%, enabling flexible selection for various voltage regulation requirements. A sharp Zener breakdown characteristic ensures precise and stable voltage clamping, while low reverse leakage current supports efficient and reliable operation in sensitive electronic circuits.
