SZBZX84C3V9LT1G Description

Short technical summary and product information.

The SZBZX84C3V9LT1G is a 3.9V Zener diode from onsemi designed for voltage regulation in space-constrained applications. It offers a nominal Zener voltage of 3.9V with ±5% tolerance and a maximum power dissipation of 225mW (250mW on FR-5 board). The device features low reverse leakage current of 3µA at 1V and a typical forward voltage of 900mV at 10mA.

 

This Zener diode is housed in a compact SOT-23-3 surface mount package, ideal for high-density PCB designs. It supports an operating temperature range of -65°C to 150°C and is rated for ESD Class 3 (>16 kV) per Human Body Model, providing robust protection in portable electronics.

 

Typical applications include voltage regulation in cellular phones, handheld portables, and other battery-powered devices. The part is RoHS compliant and Pb-free, with a flammability rating of UL 94 V-0. Supplied in tape and reel packaging with 3000 pieces per reel.
