Diodes - Zener - Single coverage a wide range of products including the SZMM5Z4V7ST1G. This part is a ‘mini’ Zener diode array, featuring two series 5.4 V Zener diodes within a single SOT-23 package. Diodes are used to control the voltage and current in electronic circuits. The SZMM5Z4V7ST1G is designed for a wide range of applications. It offers protection of sensitive components against voltage fluctuations in sensitive circuit applications, and helps to stabilize and reduce the ripple of DC power-supplies.The SZMM5Z4V7ST1G includes two Zener diodes connected in series, with each diode offering a Zener voltage of about 5.4 V, with a tight tolerance of ±5%. The rated power dissipation for the SZMM5Z4V7ST1G is typically 500 mW (1.0 W maximum). The maximum reverse current of the two diodes is specified at 50 μA minimum, at the rated Zener voltage. The maximum forward current (IF) of the diode is typically 200 mA (1.0 A maximum).The SZMM5Z4V7ST1G offers several advantages over other types of Zener diodes. First, the smaller SOT-23 form factor allows for a smaller and more compact design, which helps reduce the board space needed in a given application. Second, the dual Zener diodes reduce the number of components compared to using two traditional single Zener diodes, and can also reduce the overall cost of the design. Third, the tighter tolerance of ±5% offered by the dual Zener diodes helps ensure a more consistent and reliable operation.The working principle of a Zener diode is similar to that of a conventional diode, except that it has an additional breakdown voltage. This breakdown voltage is created by a larger doping concentration in a special p-n junction. When a reverse bias voltage is applied to the diode, the electric field within the junction region increases, causing the diode to conduct a substantial current. When Zener voltage is exceeded, the electric field becomes high enough to cause additional carriers to be generated within the junction region, and the current through the diode increases rapidly.The SZMM5Z4V7ST1G Zener diode array is an ideal solution for providing protection against voltage overshoot and providing a more consistent and reliable power supply in applications such as automated test equipment, communications networks, and industrial process control systems. The tight tolerance of the diodes provides a more consistent voltage, and the dual-diode design makes it easy to reduce part complexity and cost. This makes the SZMM5Z4V7ST1G a great solution for a wide range of applications.
