Diotec Semiconductor 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.
These Diotec Semiconductor diodes are rated for approximately 300mW total power dissipation and can operate over a wide temperature range up to +150°C, making these components suitable for consumer and industrial environments. The BZX84C is provided as a single Zener diode. At the same time, the 2BZX84C integrates two Zener diodes in a common‑anode configuration, allowing designers to reduce component count and save board space in compact designs. With features such as low dynamic resistance, high reliability, and compliance with modern environmental standards (RoHS/REACH), the BZX84C and 2BZX84C devices serve as a dependable solution for voltage stabilization, regulation, and protection in modern SMD electronics.
