MMSZ5253BT1G Description

Short technical summary and product information.

The MMSZ5253BT1G is a Zener voltage regulator diode from the MMSZ52xxxT1G series by On Semiconductor. It provides a nominal Zener voltage of 25V 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 35Ω and a reverse leakage current of 100nA at 19V. Forward voltage is 900mV at 10mA.

 

This Zener diode is designed for general-purpose voltage regulation and protection in surface mount applications. It is housed in a compact SOD-123 package, suitable for high-density automated assembly. The operating temperature range spans -55°C to 150°C, with a junction-to-ambient thermal resistance of 340°C/W.

 

The part is Pb-free and has an ESD rating of Class 3 (>16kV) per the Human Body Model. The flammability rating is UL 94 V-0. Standard packaging is tape and reel with 3000 units per reel.
