Active production — BOM-fit for 39 V rails
The 1N6014D: Rated 500 mW continuous power dissipation in the DO-35 axial package, the 39 V clamp voltage is held to ±1% tolerance, which matters when the regulation window on a 39 V rail is tight.
Temperature grade and reverse leakage
Operating range -65°C to 175°C covers military/aerospace cold-soak and high-side heat near a power device — the 100 nA max reverse leakage at 30 V reverse voltage stays low across the band, so the diode does not load the rail when it is supposed to be off. Forward voltage is 1.1 V max at 200 mA forward current — the diode conducts cleanly when forward-biased, with a predictable drop for clamping or protection circuits.
DO-204AH (DO-35) axial-lead package — the 0.020-inch diameter leads insert into standard 0.035-inch plated through-holes. The body length is about 0.165 inches, so it fits between two adjacent 0.100-inch pitch holes on a perfboard or PCB without lead forming. Supplied in Bulk — no tape-and-reel handling; suited for bench prototypes, repair kits, or low-volume production where pick-and-place is not required.
