MMSZ5251BT1G Description

Short technical summary and product information.

The MMSZ5251BT1G is a 22V Zener diode from On Semiconductor's MMSZ52xxxT1G series. It provides a nominal Zener voltage of 22V with a tolerance of ±5% and a maximum power dissipation of 500mW on FR-4 or FR-5 boards. The device features a maximum impedance of 29Ω at the Zener voltage and a reverse leakage current of 100nA at 17V. Forward voltage is specified at 900mV at 10mA.

 

This Zener diode is designed for general-purpose voltage regulation and protection applications. It offers an ESD rating of Class 3 (>16 kV) per the Human Body Model and is rated for operation from -55°C to 150°C. The package is a surface-mount SOD-123 (JEDEC) with a flammability rating of UL 94 V-0. The device is Pb-free and RoHS compliant.

 

The MMSZ5251BT1G is supplied in tape and reel packaging with a standard quantity of 3000 units per reel, suitable for automated assembly. Its small footprint allows for high-density board designs.
