The ±1% tolerance on the nominal voltage means the Zener voltage stays within 55.44 V to 56.56 V across the operating range — tighter than the standard 5% grade, which matters when the reference rail sets an ADC's full-scale or a comparator's trip point. ## DO-35 axial package and thermal range Housed in a DO-204AH (DO-35) axial-lead package, the 1N6018D mounts through-hole on a PCB or terminal strip. The body is rated for -65°C to +175°C junction temperature — a military-grade thermal envelope that suits avionics, downhole instrumentation, or engine-bay electronics where the ambient regularly exceeds 125°C. ## Leakage and forward characteristics Reverse leakage is specified at 100 nA maximum when biased at 43 V — well below the Zener knee, so the diode draws negligible current in standby circuits. Forward voltage is 1.1 V maximum at 200 mA, consistent with a standard silicon junction. Maximum Zener impedance (Zzt) is 200 Ohms, which sets the dynamic resistance at the test current.","metaTitle":"Microchip 1N6018D Zener Diode, 56 V, 500 mW, ±1%, DO-35","metaDescription":"1N6018D Zener diode from Microchip Technology: 56 V nominal, 500 mW, ±1% tolerance, DO-35 axial.
