Maximum zener impedance is 150 Ohms at the test current — the dynamic resistance shifts the output voltage slightly with load current, so for the tightest regulation the bias current should stay near the test point specified in the full datasheet. ## 500 mW in a DO-35 — thermal budget for the board Rated at 500 mW maximum power dissipation in the DO-204AH / DO-35 axial-lead package. At 43 V that works out to about 11.6 mA continuous — above that current the junction temperature climbs past the derating limit unless the leads are heat-sunk to the board copper. The junction handles extreme thermal cycling without parametric drift, which matters for avionics, downhole tools, or engine-bay electronics where the ambient sees both deep cold and sustained heat. ## Reverse leakage and forward drop — the real-world limits Maximum reverse leakage is 100 nA at 33 V reverse voltage — for a 43 V zener this means the shunt current drawn before breakdown is negligible, so it won't load a high-impedance bias node or discharge a timing capacitor prematurely. Forward voltage is 1.1 V maximum at 200 mA forward current — the diode conducts as a standard signal diode in the forward quadrant, useful if the same part doubles as a protection clamp in both polarities.","metaTitle":"Microchip 1N6015D Zener Diode, 43 V, ±1%, 500 mW, DO-35","metaDescription":"Microchip Technology 1N6015D zener diode, 43 V nominal at ±1% tolerance, 500 mW power dissipation, DO-35 axial package.
