1N2818B
DIODE ZENER 20V 50W TO204ADManufacturer: Microchip Technology
Categories: Single Zener Diodes
Quality Control: Learn More
Microchip Technology's 1N2818B is a 20V Zener diode with a 50W power rating, housed in a TO-204AD (TO-3) package for through-hole mounting. This component offers a ±5% voltage tolerance, with a nominal Zener voltage (Vz) of 20V. It exhibits a maximum Zener impedance (Zzt) of 2.4 Ohms at its specified test current, and a maximum forward voltage (Vf) of 1.5V at 10A. The device maintains a low reverse leakage current of 10 µA at 15.2V. Operating across a wide temperature range from -65°C to 175°C, the 1N2818B is suitable for applications requiring stable voltage regulation in demanding environments, including industrial power supplies and automotive systems.
