BZX84C5V1ET3G Description

Short technical summary and product information.

The BZX84C5V1ET3G is a Zener voltage regulator diode from onsemi, offering a nominal Zener voltage of 5.1V with a tolerance of ±6%. It is designed for surface mount applications and dissipates up to 250mW on FR-5 board, with a peak power rating of 225W for 8x20 µs pulses. The device features a low maximum impedance of 60Ω at the Zener test point and a reverse leakage current of 2µA at 2V. Forward voltage drop is 900mV at 10mA.

 

Housed in a compact SOT-23-3 (TO-236) package, the diode is suitable for high density PCB designs. It supports an operating temperature range of -65°C to 150°C and has a thermal resistance of 500°C/W junction-to-ambient on FR-5 board. The device is ESD rated Class 3 (>16 kV) per the Human Body Model, ensuring robust protection in handling and operation.

 

Common applications include voltage regulation in cellular phones, handheld portables, and other battery-powered devices requiring efficient space utilization. The BZX84C5V1ET3G is RoHS compliant and Pb-free, with a flammability rating of UL 94 V-0. Available in tape and reel packaging with 10,000 pieces per reel.
