Product details

400 V peak reverse, 1.9 A average — the rectifier for low-power AC-DC rails

The VS-2KBB40R is a Vishay single-phase bridge rectifier in a through-hole 4-SIP (2KBB) package, rated for 400 V peak reverse voltage and 1.9 A average rectified output current (Io).

Active production, ROHS3 — no end-of-life risk for new BOMs

The 4-SIP (2KBB) package is a standard Vishay bridge-rectifier footprint, shared across the 2KBB family; board layouts for this package are well-established, and the through-hole leads simplify hand-assembly or wave-solder rework.
