BZX84C18LT1 Description

Short technical summary and product information.

The BZX84C18LT1 is a Zener voltage regulator diode from On Semiconductor, part of the BZX84C2V4LT1 series. It provides a nominal Zener voltage of 18V with a tolerance of ±6%, making it suitable for voltage regulation and clamping applications in compact electronic designs.

 

This diode is rated for a maximum power dissipation of 225mW on an FR-5 board at 25°C, with a derating factor of 1.8 mW/°C above 25°C. It features a maximum forward voltage of 900mV at 10mA and a reverse leakage current of 50nA at 12.6V. The device offers an ESD rating of Class 3 (>16 kV) per the Human Body Model, enhancing its robustness in handling.

 

The BZX84C18LT1 is housed in a SOT-23-3 surface mount package, also known as TO-236-3 or SC-59. It is designed for automated board assembly and is well-suited for high-density PCBs. The device is supplied in tape and reel packaging for efficient manufacturing.
