VOLTAGE REGULATORManufacturer: Microchip Technology
Categories: Single Zener Diodes
Quality Control: Learn More
Microchip Technology's 1N2818BU3 is a 20V Zener diode with a significant 50W power rating and a ±5% voltage tolerance. Designed for surface mount applications, this component utilizes the U3 (SMD-0.5) package for efficient thermal management. Key electrical characteristics include a maximum impedance of 2.4 Ohms at its Zener voltage and a low reverse leakage current of 10 µA at 15.2V. The diode exhibits a forward voltage of 1.5V at 10A. Operating across a wide temperature range of -65°C to 175°C (TJ), the 1N2818BU3 is a robust solution for voltage regulation and protection circuits in demanding applications such as industrial power supplies and high-reliability systems.
