The RMB2S-E3/80: The Vishay RMB2S-/80 is a single-phase bridge rectifier in a surface-mount TO-269AA (MBS) package, designed for full-wave rectification of AC line voltages up to 200 V peak reverse. Rated for 500 mA average rectified output current (Io) with a forward voltage drop of 1.25 V max at 400 mA — the Vf figure sets the conduction loss budget in the BOM thermal calculation.
The supplier device package is designated TO-269AA (MBS) — the same mechanical outline as the industry-standard MBS package, so existing PCB layouts for that footprint accept this part without a board spin.
