The MM1Z56B with Zener Diodes SOD-123 RoHS is a rectifier diode manufactured by Jingdao. It is designed to work with 6.2 V to 75 V inputs and features a low reverse power consumption of 500 mW, making it suitable for applications where efficiency is a concern. The diode is also RoHS compliant, meaning it is free of hazardous substances such as lead, mercury, and cadmium. It is housed in a low-profile, SOD-123 package that is lead-free, halogen-free, and available in a variety of colors. This makes the device a great choice for consumer electronics that require minimal size and environmental friendliness.
