MMSZ5245CT1G

The MMSZ5245CT1G is a Zener voltage regulator diode from On Semiconductor's MMSZ52xxxT1G series. It provides a nominal Zener voltage of 15V with a tolerance of ±2% and a maximum power dissipation of 500mW on FR-4 or FR-5 board. Key electrical characteristics include a typical forward voltage of 900mV at 10mA, a maximum Zener impedance of 16Ω at the test current, and a reverse leakage current of 100nA maximum at 11V. The device is rated for operating junction temperatures from -55°C to 150°C, with a junction-to-ambient thermal resistance of 340°C/W and junction-to-lead thermal resistance of 150°C/W.

The diode is housed in a standard SOD-123 surface mount package, designed for automated board assembly. It features an ESD rating of Class 3 (>16kV) per the Human Body Model and a UL 94 V-0 flammability rating. The part is Pb-free and designed for general purpose, medium current voltage regulation applications.

This Zener diode is suitable for use in voltage reference, overvoltage protection, and clamping circuits where a stable 15V reference is required with moderate power handling in a compact footprint. The SOD-123 package allows for high-density placement on printed circuit boards.
