MMSZ5225-V to MMSZ5267-V are Silicon Planar Power Zener Diodes produced by Vishay Semiconductors. Standard Zener voltage tolerance is ± 5 % with a “B” suffix (e.g.: MMSZ5225B-V), suffix “C” is ± 2 % tolerance
The Vishay MMSZ5225‑V to MMSZ5267‑V series are small‑signal Zener diodes offered in several case styles, including SOD123, MiniMELF, DO‑35 and SOT‑23. The devices are lead‑free, RoHS compliant, and provide standard Zener voltage tolerances of ±5 % (B suffix) or ±2 % (C suffix).
Key electrical characteristics include a maximum power dissipation of 500 mW at 75 °C, a thermal resistance of 340 K/W, and a maximum junction temperature of 150 °C. Mechanical data list a plastic SOD123 case weighing approximately 9.3 mg, with various packaging options.
