1N4114UR/TR

Single Zener Diodes Overview

The Microchip Technology 1N4114UR/TR is a glass surface mount Zener voltage regulator with a nominal voltage of 20 V. It operates within a temperature range of -65°C to +175°C and dissipates up to 0.5 W at an end cap temperature below 100°C. The device features a maximum reverse leakage current of 10 nA, a Zener impedance of 150 Ohms, and a test current of 250 µA. Packaged in the DO-213AA (SOD80/MLL34) MELF style, it utilizes tape and reel packaging for automated assembly.
