MMSZ5222BT1G Description

Short technical summary and product information.

The MMSZ5222BT1G is a Zener voltage regulator diode from On Semiconductor, part of the MMSZ52xxxT1G series. It provides a nominal Zener voltage of 2.5V with a tolerance of ±5% and a maximum power dissipation of 500mW when mounted on FR-4 or FR-5 boards.

 

This device features a maximum impedance (Zzt) of 30Ω and a typical forward voltage of 900mV at 10mA. The maximum reverse leakage current is 100µA at 1V. It is designed for general-purpose voltage regulation and clamping applications requiring medium current.

 

The MMSZ5222BT1G is housed in a void-free, transfer-molded SOD-123 surface-mount package. It supports an operating temperature range of -55°C to 150°C and has a junction-to-ambient thermal resistance of 340°C/W. The device is Pb-free and has an ESD rating of Class 3 (>16 kV) per the Human Body Model.
