SZMMSZ5231BT1G Description

Short technical summary and product information.

The SZMMSZ5231BT1G is a 5.1V Zener diode from ON Semiconductor's SZMMSZ52xxxT1G series. It features a maximum power dissipation of 500mW on FR-4 or FR-5 board at 75°C lead temperature, with a derating factor of 6.7 mW/°C above 75°C. The device has a tolerance of ±5%, a maximum impedance of 17Ω, and a reverse leakage current of 5µA at 2V. Forward voltage is 900mV at 10mA. It is designed for general-purpose voltage regulation and overvoltage protection in low-power circuits. The operating temperature range is -55°C to +150°C. The SOD-123 package is surface mountable and designed for automated assembly. The device is AEC-Q101 qualified for automotive applications, has an ESD rating of >16kV (Human Body Model), and is Pb-Free with UL 94 V-0 flammability rating.
