MMSZ3V3T1G Description

Short technical summary and product information.

The MMSZ3V3T1G is a 3.3V Zener diode from the MMSZxxxT1G series by onsemi. It offers a nominal Zener voltage of 3.3V with ±5% tolerance and a maximum Zener impedance of 95Ω at 20mA test current. Forward voltage is typically 900mV at 10mA, and reverse leakage current is 5µA maximum at 1V. The device is rated for 500mW total power dissipation on FR-5 board, derated above 75°C at 6.7mW/°C. Operating temperature range is -55°C to 150°C. It features an ESD rating of Class 3 (>16kV) per Human Body Model and flammability rating UL 94 V-0. Thermal resistance is 340°C/W junction-to-ambient and 150°C/W junction-to-lead. The SOD-123 surface mount package is void-free, transfer-molded plastic with corrosion-resistant finish and cathode polarity band. Supplied in tape and reel packaging with 3000 pieces per reel.
