The MM1Z20 with Zener Diodes SOD-123 RoHS manufactured by Jingdao is a surface mount device (SMD) that provides a high reliability, low voltage SOD-123 package. Specifically, it is a dual zener diode with a zener voltage of 2.4V and 4.3V, respectively, and a power dissipation rating of 500mW. The MM1Z20 has a glass passivated junction, RoHS compliance, and an electrically isolating package in both single and dual bipolar configurations. This allows for a wide variety of applications such as low voltage protection, testing, or voltage clamping in a variety of consumer and industrial equipment, including computers and home appliances.
