The 3EZ20D5 is a 20V, 3W Zener diode manufactured by EIC discrete Semiconductors. Zener diodes are semiconductor devices that allow current to flow in either forward or reverse direction. The diode consists of a specially doped p-n junction designed to conduct in the reverse direction when a certain voltage is reached. This voltage is known as the Zener voltage. They are commonly used to regulate voltage in circuits.
