82 V Zener in a hermetically sealed DO-213AA package
The 1N6022UR/TR is an 82 V Zener diode rated for 500 mW continuous power dissipation in the DO-213AA surface-mount package — a hermetically sealed glass body suited for applications where the board sees wide temperature swings or corrosive atmospheres.
Package and temperature grade
DO-213AA (MELF-style) is a two-terminal cylindrical package with metallised end caps — the body is glass, not moulded epoxy, so it resists moisture absorption and does not require bake-out before reflow. The -65 °C to 175 °C rating means this diode can be used in a circuit that must survive -55 °C storage and 150 °C continuous junction temperature with margin; the glass seal prevents parameter drift under thermal cycling.
