The ON Semiconductor MMSZ5248BT1 is a Zener voltage regulator diode designed for general-purpose, medium-current applications. It is housed in a compact SOD-123 surface mount package, suitable for high-density board designs and automated assembly.
This device offers a power dissipation rating of 500 mW on an FR-5 board at 75°C, with power derating above this temperature. The Zener voltage is nominally 18V with a ±5% tolerance, and it exhibits a low reverse leakage current of 100 nA at 14V. The operating temperature range spans from -55°C to 150°C, ensuring reliability in various environmental conditions.
The MMSZ5248BT1 series is Pb-Free and features a flammability rating of UL 94 V-0. Its ESD rating is Class 3 (> 16 kV) per the Human Body Model. The device is designed for optimal automated board assembly and provides a convenient alternative to leadless package styles.
Key electrical characteristics include a Zener impedance of 21 Ω (maximum). The wide Zener reverse voltage range for the series is 2.4V to 110V at thermal equilibrium.
