The 2EZ51D5 Zener Diode with DO-41 RoHS by SUNMATE is a standard component used in power circuitry and other applications to provide a pulsed voltage regulator and/or voltage reference. It features a single-diode push-pull configuration made with a single, axial-leaded, planar-style Zener diode housed in a DO-41 ROHS package. This diode offers a robust, user-friendly design with low reverse leakage current, a wide adjustable voltage range, and superior temperature stability. When reverse voltage is applied, the diode begins to conduct until the breakdown voltage is reached, at which point the current flow is limited. Ultimately, this diode is used to regulate voltages in various applications and ensure a stable and consistent power system.
