Available in Tape & Reel (TR) for automated pick-and-place or Cut Tape (CT) for prototype and low-volume builds — the reel quantity is the standard 7-inch reel count for this body size. Single-phase bridge topology — four diodes in a full-wave configuration inside one package, so the PCB layout needs only four pads (two AC inputs, DC+ and DC-) instead of four discrete diodes and their routing.","metaTitle":"Vishay DF04SA-E3/77 Bridge Rectifier, 400V, 1A, DFS","metaDescription":"Vishay DF04SA-E3/77 single-phase bridge rectifier, 400V peak reverse, 1A average, DFS SMD package.
