SZMMBZ5231BLT3G Description

Short technical summary and product information.

The SZMMBZ5231BLT3G is a Zener voltage regulator diode from On Semiconductor, part of the MMBZ52xx series. It provides a nominal Zener voltage of 5.1V with ±5% tolerance, suitable for voltage regulation in low-power circuits.

 

This device is rated for a maximum power dissipation of 225mW on FR-4 or FR-5 boards. It features a low maximum impedance of 17 Ohms (Zzt) and a reverse leakage current of 5µA at 2V. The forward voltage is 900mV at 10mA. The operating temperature range is -65°C to 150°C.

 

The diode is housed in a surface mount SOT-23-3 package (also known as TO-236-3 or SC-59), making it ideal for high-density PCB designs. It is designed for automated assembly and is suitable for applications such as cellular phones, handheld portables, and other space-constrained electronics.

 

The SZMMBZ5231BLT3G is qualified for automotive applications (AEC-Q101) and has an ESD rating of Class 3 (>16kV) per Human Body Model. It is Pb-Free, Halogen Free/BFR Free, and RoHS compliant. The flammability rating is UL 94 V-0.
