Its forward voltage is 450 mV maximum at 10 mA, keeping conduction loss low in signal-level circuits, while reverse leakage is 5 µA at 75 V. ## Through-hole DO-35 — rework-friendly, but plan the assembly The BAT46 comes in a DO-204AH (DO-35) axial-lead package, which is straightforward to hand-solder or wave-solder but requires through-hole board real estate. The cathode band is clearly marked on the body; orientation is unambiguous, which helps during manual rework and inspection.","metaTitle":"BAT46 Schottky Diode, 100 V, 150 mA, DO-35","metaDescription":"STMicroelectronics BAT46 Schottky diode, 100 V reverse, 150 mA forward, 450 mV Vf at 10 mA, DO-35 through-hole package.
