MMBZ5250BLT1G

The MMBZ5250BLT1G is a 20V Zener diode from On Semiconductor, part of the MMBZ52xxBLT1G series. It is designed for voltage regulation in space-constrained applications, offering a nominal Zener voltage of 20V with ±5% tolerance. The device features a maximum power dissipation of 225mW on FR-5 board, with a derating factor of 1.8 mW/°C above 25°C. It has a maximum impedance of 25Ω at the Zener test point, and a low reverse leakage current of 100nA at 15V reverse voltage. The forward voltage is 900mV maximum at 10mA forward current.

This Zener diode is housed in a surface mount SOT-23-3 package, ideal for high-density PCB designs. It supports an operating temperature range of -65°C to 150°C, and offers thermal resistance of 556°C/W (junction-to-ambient on FR-5 board) and 417°C/W on alumina substrate. The device is ESD rated Class 3 (>16 kV) per Human Body Model, providing robust protection in handling and operation.

The MMBZ5250BLT1G is compliant with RoHS3, Pb-Free, and Halogen Free/BFR Free standards, and has a UL 94 V-0 flammability rating. It is suitable for a variety of applications including cellular phones, handheld portables, and other portable electronics requiring efficient voltage regulation in a compact footprint.
