The ZM4743A with LL-41 Zener Diodes ROHS manufactured by SLKORMICRO is an a dual Zener diode constructed of two 500 mW, 0.22V reverse breakdown voltage PNPN, dual Zener diodes in a SOT-323 package. It provides greater reverse breakdown voltage and lesser forward current than single Zener diodes. The device is manufactured using the latest high voltage PNPN technology and is RoHS compliant. It offers excellent clamping capability, good ESD protection and low leakage current. The device is designed to withstand high levels of thermal and electrical stress. It is suitable for a wide variety of applications, including voltage clamping, surge protection, ESD protection, overvoltage protection, and general voltage regulation.
