The 1 kV PIV means this bridge handles 240 VAC mains with a 1.4× peak factor plus margin for line transients — common in off-line power supplies and AC-DC front ends where the rectifier sees the full peak of the sine wave. The 3.5 A average rating, at a 1.05 V forward drop at 10 A surge, keeps conduction losses under 3.7 W in continuous duty, which the isoCINK+ package can dissipate with basic airflow or a heatsink tab. ## isoCINK+ BU — through-hole package and board integration The 4-SIP BU package (isoCINK+™) is a through-hole, single-in-line footprint with four leads — two for the AC input, two for the DC output. Supplied in Bulk (tube or tray), the package suits hand-insertion or wave-solder assembly on standard 2.54 mm pitch boards. The through-hole leads provide mechanical robustness in high-vibration environments compared to surface-mount bridges of similar rating. Reverse leakage is specified at 5 µA at 1000 V reverse — a low figure that confirms the die passivation and junction termination are clean, important for high-impedance loads where leakage current can upset bias networks. ## Active production and compliance Manufactured by Vishay, a Tier-1 discrete semiconductor house, the part carries the full datasheet with SOA curves, thermal impedance, and surge ratings. The suffix denotes RoHS-compliant lead-free plating on the leads.","metaTitle":"Vishay BU2010-E3/51 Bridge Rectifier, 1 kV, 3.5 A","metaDescription":"Vishay BU2010-E3/51 single-phase bridge rectifier, 1 kV PIV, 3.5 A Io, 1.05 Vf, isoCINK+ BU package, active production, ROHS3 compliant.
