1N6018UR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N6018UR-1/TR is a surface mount Zener diode in the 1N5985BUR-1 through 1N6031BUR-1 series. It features a hermetically sealed glass DO-213AA (MELF) package with tin-lead or matte-tin end caps. The device provides a nominal Zener voltage of 56V at a test current of 2.0mA, with a maximum dynamic impedance of 200 Ohms and a typical temperature coefficient of +0.096%/°C. It supports a power dissipation of 0.5 Watts and operates within a junction temperature range of -65°C to +175°C.
