That ±5% window is standard for a general-purpose zener and sets the regulation accuracy for the rail or reference it clamps. ## 500 mW power — the thermal ceiling in a hermetic package Rated for 500 mW maximum power dissipation. The -65°C to 175°C junction temperature range covers military/aerospace and downhole environments where standard plastic-packaged zeners would fail.","metaTitle":"Microchip 1N6318US/TR Zener Diode, 5.6 V, 500 mW, SQ-MELF","metaDescription":"Microchip 1N6318US/TR active-production zener diode, 5.6 V ±5%, 500 mW, SQ-MELF B package, -65°C to 175°C.
