The SMF47**A series Zener diodes adopt a compact SOD-123FL package and offer 1W power dissipation with Zener voltage ranging from 3.3V to 100V. Designed for high-precision voltage regulation and protection, this series features low leakage current (IR), high surge capability (IZM), and excellent thermal stability (Tj: -55℃ to +150℃), making it ideal for applications such as portable devices, power modules, charging systems, and communication terminals.
