The ONSEMI BZX84B18LT1G series of Zener diodes provides voltage regulation in a compact SOT-23 surface mount package. These diodes are ideal for applications requiring minimal space, such as cellular phones, portable devices, and high-density printed circuit boards. They are characterized by their small package size, ease of automated board assembly, and ESD rating of Class 3 (> 16 kV). The series offers a range of Zener breakdown voltages from 2.4V to 75V, with options for tight tolerance and automotive-grade qualification.
