onsemi MMSZ5255BT1G Zener Diode is a high-quality discrete semiconductor designed for use as a voltage regulator. This single diode configuration provides a nominal zener voltage of 28 V with a ±5% tolerance, suitable for protecting circuits and stabilizing voltage in various industrial and electronic applications.
Its compact surface mount SOD-123 package with 2 pins ensures easy integration into densely packed printed circuit boards. The diode is capable of dissipating up to 500 mW power, making it ideal for low to moderate power electronic and semiconductor equipment.
The device operates reliably over a wide temperature range from -55°C to 150°C, supporting applications in automotive-grade environments and industrial electronics where temperature extremes are common. Maximum reverse leakage current is extremely low at 100 nA, reducing unnecessary power loss and increasing circuit efficiency.
This diode has a test current of 4.5 mA and a maximum zener impedance of 44 ohms, which ensures stable voltage regulation performance for sensitive electronics. The height of 1.35 mm and length of 3.86 mm facilitate precise surface mounting on PCBs.
