The ±1% tolerance is tighter than the standard ±5% you see on most Zeners in this voltage class — useful if you need a stable reference or clamp threshold without trimming. ## 180 V Zener — where the 500 mW rating matters At 180 V nominal, the 500 mW power limit means the diode can handle about 2.8 mA continuous before you exceed the dissipation budget (Pmax / Vz). If your circuit needs to sink more current — say for a shunt regulator — you either parallel devices or move to a higher-power package. The 1.7 kOhms Zzt impedance at that current tells you the regulation slope: a 1 mA change in current shifts the Zener voltage by roughly 1.7 V. Reverse leakage is specified at 100 nA maximum with 137 V across the junction — that is 76% of the nominal Zener voltage. For a precision clamp or reference, this low leakage means the diode does not load the node until it reaches the breakdown knee. The -65°C to 175°C operating temperature range covers military and industrial extremes — avionics, downhole tools, or engine-bay electronics where the ambient can hit 125°C and self-heating adds another 50°C margin. ## DO-35 axial package — board-fit reality The DO-35 (DO-204AH) glass body is 0.166 inches long with 0.020-inch diameter leads. Through-hole mounting means the leads need forming for PCB insertion — the glass body is brittle, so bend radius matters to avoid cracking the seal. The 1N6030D ships in Bulk packaging, so you get loose parts, not tape-and-reel. Forward voltage is 1.1 V maximum at 200 mA — that is the conduction drop when the diode is forward-biased. For reverse-polarity protection or clamping, the 200 mA surge rating gives you a rough idea of the non-repetitive peak current the junction can survive before the 500 mW steady-state limit kicks in.","metaTitle":"Microchip 1N6030D Zener Diode, 180 V, ±1%, 500 mW, DO-35","metaDescription":"1N6030D from Microchip Technology: 180 V Zener diode in DO-35 axial package, ±1% tolerance, 500 mW power dissipation.

This is tighter than the typical ±5% or ±10% you see on general-purpose Zeners. For a voltage reference or precision clamp, the ±1% grade eliminates the need for a trim pot or a separate reference IC — the diode itself holds the threshold within 1.8 V of 180 V across the operating temperature range."},{"question":"What package does the 1N6030D come in?","answer":"The 1N6030D is supplied in a DO-35 (DO-204AH) axial-lead glass package, through-hole mount.
