BZX84C18LT1G Description

Short technical summary and product information.

The BZX84C18LT1G is a 18V Zener diode from onsemi's BZX84C series, designed for voltage regulation in space-constrained applications. It features a nominal zener voltage of 18V with ±6% tolerance and a maximum power dissipation of 250mW on FR-4 or FR-5 boards. The device offers a low reverse leakage current of 50 nA at 12.6V and a forward voltage of 900mV at 10mA.

 

This Zener diode is housed in a standard SOT-23-3 surface mount package (also known as TO-236 or SC-59), making it suitable for automated assembly. It includes a high ESD rating of Class 3 (>16 kV) per the Human Body Model, enhancing robustness in handling and operation. The operating junction temperature range spans -65°C to 150°C.

 

Typical applications include voltage regulation in cellular phones, handheld portables, and high-density PC boards. The device is Pb-free and RoHS compliant, meeting environmental requirements for lead-free soldering. The maximum soldering temperature is 260°C for 10 seconds, with a flammability rating of UL 94 V-0.
