ROHM offers a wide lineup of Zener diodes designed to meet various application requirements and needs. Power ratings range from 100mW to 1W. Zener Diodes are available in many different voltages and package sizes, including one of the smallest on the market (GDZ series). In addition, ultra-low-capacitance models as low as 0.3pF are available for use as ESD surge protection devices in automotive systems and high-speed signal lines, such as USB 2.0. Additionally, the popular RSB series offers bidirectional (positive and negative) surge protection in a single package which is ideal for high-density applications where space saving is key.
