MMSZ5231BT3G Description

Short technical summary and product information.

The MMSZ5231BT3G is a 5.1V Zener diode from On Semiconductor, designed for voltage regulation and general purpose applications. It offers a nominal Zener voltage of 5.1V with ±5% tolerance and a maximum power dissipation of 500mW on FR-4 or FR-5 boards. The device features a maximum impedance of 17Ω at the Zener test current, reverse leakage current of 5µA at 2V, and a typical forward voltage of 900mV at 10mA.

 

This Zener diode is housed in a surface mount SOD-123 package, optimized for automated assembly and high-density PCB designs. It operates over a junction temperature range of -55°C to 150°C and has thermal resistance of 340°C/W junction-to-ambient and 150°C/W junction-to-lead. The device is ESD rated Class 3 (>16 kV) per Human Body Model and meets UL 94 V-0 flammability rating.

 

The MMSZ5231BT3G is supplied in tape and reel packaging with a standard quantity of 10,000 pieces. It is Pb-Free and RoHS3 compliant (unverified). This part is suitable for voltage clamping, overvoltage protection, and reference voltage generation in low-power circuits.
