SZMMBZ5252BLT1G Description

Short technical summary and product information.

The SZMMBZ5252BLT1G is a 24V Zener diode from onsemi's MMBZ52xxBLT1G series, offered in a surface mount SOT-23-3 package. It provides voltage regulation with a nominal Zener voltage of 24V and a tolerance of ±5%. The device is rated for 225 mW power dissipation on FR-5 board and 300 mW on alumina substrate, making it suitable for low-power applications.

 

Key electrical characteristics include a maximum Zener impedance of 33 Ω, a reverse leakage current of 100 nA at 18 V, and a forward voltage of 900 mV at 10 mA. The diode is ESD rated Class 3 (>16 kV) per the Human Body Model, enhancing robustness in handling and operation.

 

The SOT-23-3 package is designed for automated assembly and high-density PCB layouts. The device is AEC-Q101 qualified for automotive applications, Pb-free, halogen-free/BFR-free, and RoHS compliant. Typical applications include voltage regulation in cellular phones, handheld portables, and other portable electronics.
