SZMMBZ5231BLT1G Description

Short technical summary and product information.

The On Semiconductor SZMMBZ5231BLT1G is a Zener voltage regulator diode from the MMBZ52xxBLT1G series. It provides a nominal Zener voltage of 5.1V with a tolerance of ±5% and a maximum power dissipation of 225mW on an FR-5 board. This device is designed for voltage regulation in space-constrained applications.

 

Key electrical characteristics include a maximum impedance (Zzt) of 17 Ω, a maximum reverse leakage current of 5 µA at 2V, and a typical forward voltage of 900mV at 10mA. The device is rated for an operating temperature range of -65°C to 150°C and features an ESD rating of Class 3 (>16 kV) per the Human Body Model.

 

The SZMMBZ5231BLT1G is housed in a surface mount SOT-23-3 (TO-236) package, suitable for automated assembly. It is AEC-Q101 qualified for automotive applications and is Pb-Free, Halogen Free/BFR Free, and RoHS compliant.
