MMSZ52x SMD Planar Zener Diodes

Diotec Semiconductor MMSZ52x SMD Planar Zener Diodes are capable of delivering sharp Zener voltage breakdown. These diodes offer low leakage current and 500mW power dissipation. The MMSZ52x Zener diodes are available in low-profile packages that are built with UL 94V-0 case materials and are compliant with RoHS, REACH, and conflict minerals. Typical applications include voltage stabilization and regulation, and commercial grade.
