BZX84C3V9LT1G Description

Short technical summary and product information.

The BZX84C3V9LT1G from On Semiconductor is a Zener voltage regulator diode designed for voltage regulation in space-constrained applications. This device features a nominal Zener voltage of 3.9V with a tolerance of ±5%, making it suitable for precision voltage reference and clamping circuits.

 

The diode is rated for a maximum power dissipation of 250mW when mounted on FR-4 or FR-5 board at 25°C ambient temperature. It offers a maximum Zener impedance of 90 Ω at the Zzt test current and a low leakage current of 3 µA maximum at a reverse voltage of 1V. The forward voltage is specified at 900 mV maximum at a forward current of 10 mA.

 

The BZX84C3V9LT1G is housed in a surface mount SOT-23 package, also known as TO-236-3 or SC-59, and is supplied in tape and reel packaging with a standard quantity of 3000 pieces. It supports an operating temperature range of -65°C to 150°C junction temperature and has an ESD rating of Class 3 (>16 kV) per the Human Body Model.

 

This Zener diode is RoHS compliant and Pb-Free, meeting environmental requirements for lead-free soldering. The package flammability rating is UL 94 V-0.
