That 800 V rating gives comfortable margin on a 240 VAC line — typical peak is 340 V, so you have over 2× headroom for mains transients without avalanche stress. ## Forward drop and thermal budget in a small SMD body Forward voltage is 1.1 V maximum at 1.5 A. In the DFS package with gull-wing leads, the heat path is through the copper pads. Vishay lists the DF1508S-/77 as Active with ROHS3 compliance. ## Rework and footprint notes The DFS package has gull-wing leads — the leads are visible and probe-able, which makes post-reflow inspection straightforward.","metaTitle":"Vishay DF1508S-E3/77 Bridge Rectifier, 800 V, 1.5 A, DFS","metaDescription":"Vishay DF1508S-E3/77 single-phase bridge rectifier, 800 V peak reverse, 1.5 A average, 1.1 Vf at rated current.
