The document describes the features and characteristics of the MMSZ4681 to MMSZ4717 series of Zener diodes. They are silicon planar Zener diodes with a standard Zener voltage tolerance of ±5%, with other tolerances available upon request. These diodes are guaranteed for high temperature soldering at 250°C/10 seconds. They are available in SOD-123 plastic case with a weight of approximately 0.01 grams. The document also provides the dimensions and electrical characteristics of each diode model.
