This is an active-production part — no end-of-life or NRND notice to track, so it remains a standard BOM line for voltage regulation, clamping, and reference circuits. ## Wide temperature range and low leakage Reverse leakage is specified at 100 nA maximum at 25 V reverse voltage — 8 V below the zener knee — so the diode draws negligible current in the off state, important for battery-powered bias networks and precision voltage references. Maximum zener impedance (Zzt) is 88 Ohms at the test current. This impedance affects the regulation slope: at lower bias currents the dynamic resistance rises, so the output voltage shifts more with current variation. For the tightest regulation, bias the diode at or above the manufacturer's test current. ## DO-35 axial package — through-hole board integration The DO-204AH (DO-35) axial leaded package is the standard through-hole footprint for 500 mW zeners. The glass body and tin-plated copper leads handle wave soldering and manual rework without issue. Bulk packaging means the diodes ship loose in a bag or tube — no tape-and-reel, so pick-and-place requires hand insertion or a tube feeder.","metaTitle":"1N6012D Zener Diode, 33 V, ±1%, 500 mW, DO-35, Active","metaDescription":"Microchip Technology 1N6012D 33 V zener diode, ±1% tolerance, 500 mW, DO-35 axial.
