MMSZ5237BT1G Description

Short technical summary and product information.

The MMSZ5237BT1G is a 8.2V Zener diode from onsemi's MMSZ52xxxT1G series, designed for voltage regulation in surface mount applications. It offers a nominal Zener voltage of 8.2V with ±5% tolerance and a maximum power dissipation of 500mW on FR-4 or FR-5 boards. Key electrical characteristics include a maximum impedance of 8Ω, forward voltage of 900mV at 10mA, and reverse leakage current of 3µA at 6.5V.

 

This device is housed in a compact SOD-123 package, suitable for automated assembly and high-density designs. It features an ESD rating of Class 3 (>16 kV) per Human Body Model and is rated for operating temperatures from -55°C to 150°C. The package is Pb-Free and has a flammability rating of UL 94 V-0.

 

Typical applications include voltage regulation, overvoltage protection, and reference voltage generation in low-power circuits. The part is supplied in tape and reel packaging with 3,000 units per reel.
