The 1SMA4750A with Zener Diodes SMA RoHS manufactured by Jingdao is a small, surface-mount device that is designed for overvoltage protection in portable electronic devices and other sensitive equipment. It features a Zener diode array composed of two Silicon Zener diodes in series, in a standard small outline package with RoHS compliant lead (Pb)-free terminals. It is designed to protect against voltage spikes up to 50V that can be caused by electrostatic discharge or other transient events. In addition to its protection capabilities, it also features a low forward voltage drop, low reverse current leakage, and fast recovery time. The 1SMA4750A has excellent heat resistance and is designed to withstand a reflow soldering process up to 260°C without exhibiting any connection failure.
