The Vishay BZX84C18-E3-18 is a silicon planar Zener diode with a nominal Zener voltage of 18V and a tolerance of ±5%. It is part of the BZX84 series, designed for general purpose voltage regulation and protection applications. The diode offers a maximum power dissipation of 300mW on an FR-4 board (500mW total) and operates over a temperature range of -55°C to 150°C.
This device is housed in a compact SOT-23-3 surface mount package, suitable for automated assembly. It features a low maximum impedance of 45Ω at the test current and a reverse leakage current of 50nA at 12.6V. The diode is ESD rated to >8kV HBM and >800V MM, making it robust for handling in manufacturing.
Typical applications include voltage clamping, overvoltage protection, and reference voltage generation in consumer, industrial, and automotive electronics (AEC-Q101 qualified variants available). The package is RoHS3 compliant and MSL level 1, compatible with lead-free soldering processes up to 260°C peak temperature.
