SZMM5Z4V3T1G Description

Short technical summary and product information.

The SZMM5Z4V3T1G is a Zener voltage regulator diode from ON Semiconductor, part of the SZMM5ZxxxT1G series. It provides a nominal Zener voltage of 4.3V with a tolerance of ±7%. The device is rated for a maximum power dissipation of 500mW at 25°C ambient temperature on an FR-4 board, with derating above 25°C at 4.0mW/°C. It features a maximum Zener impedance of 90Ω and a typical forward voltage of 900mV at 10mA. The reverse leakage current is a maximum of 3µA at 1V reverse voltage.

 

The diode is packaged in a SOD-523 surface mount case, which measures 1.20mm x 0.80mm with a low body height of 0.7mm. It is designed for space-constrained applications such as cellular phones, handheld portables, and high-density PC boards. The device is qualified to AEC-Q101 for automotive applications and has an ESD rating of Class 3 (>16kV) per Human Body Model. It is Pb-free and RoHS compliant, with a maximum reflow temperature of 260°C and MSL Level 1 rating.
