ONSEMI MMSZ4703T1G Zener Diode

These Zener diodes are surface-mount devices rated at 500 mW, offering a wide reverse voltage range from 1.8 V to 43 V. Designed for high-density PCB applications, they feature a corrosion-resistant, easily solderable plastic case with UL 94 V-0 flammability rating. Suitable for automotive, industrial, and control applications, they are RoHS compliant and Pb-free, with excellent ESD class 3 (> 16 kV) protection. Mechanical specifications include a void-free transfer-molded case, a maximum soldering case temperature of 260°C for 10 seconds, and thermal resistance of approximately 3,000 °C/W junction-to-ambient. These characteristics ensure reliable performance under varied operating conditions.
