With a ±1% tolerance on the nominal voltage, this part suits precision voltage-reference or clamping applications where the setpoint must stay tight across the operating range. ## Leakage and impedance at the test point Reverse leakage is specified at 100 nA maximum when the applied voltage is 152 V — 76% of the nominal zener voltage — so the diode stays well below its breakdown knee in the blocking state. Maximum zener impedance (Zzt) is 2 kOhms at the test current, a figure that governs the regulation slope: a 1 mA change in bias current shifts the output voltage by up to 2 V. The junction operates from -65°C to 175°C, covering military-temperature applications — avionics, downhole instrumentation, or satellite power rails where the ambient floor is well below -40°C. Housed in a DO-35 (DO-204AH) axial-lead glass package, it mounts through-hole on a PCB or terminal strip; the glass body is hermetic and resists moisture ingress better than molded epoxy in high-humidity storage.","metaTitle":"1N6031D Zener Diode, 200 V, 500 mW, DO-35, Microchip","metaDescription":"1N6031D Zener diode, 200 V nominal, 500 mW, ±1% tolerance, DO-35 axial.
