It uses standard silicon technology and comes in the 4-SMD gull-wing DFS package, which sits low on the board and suits automated pick-and-place assembly. The 800 V peak reverse rating covers 240 VAC mains with margin — a universal-input offline supply rectifying 85–265 VAC sees peak voltages around 375 V, so this part stays well inside its blocking capability. At 1 A average rectified output, the forward drop is 1.1 V max at 1 A — that is 1.1 W conduction loss at full load, which the DFS package dissipates through the board copper without needing a heatsink in most designs. ## Active production and compliance It is ROHS3 compliant, meaning no restricted substances above the threshold limits — no exemption expiry to track for EU-market builds.","metaTitle":"Vishay DF08S-E3/77 Bridge Rectifier, 800V 1A, DFS","metaDescription":"Vishay DF08S-E3/77 single-phase bridge rectifier, 800V peak reverse, 1A average.
