Product details

What this 30 V, 100 mA common-anode Schottky does for a BOM

The RB557WMTL: The 490 mV forward drop at 100 mA keeps conduction loss low enough for battery-operated protection or OR-ing strings. In a common-anode pair, the two cathodes are independent — the part clamps two separate rails to a shared positive bus, or serves as the upper half of a dual-rail polarity-protection bridge.

Housed in the SC-89 (SOT-490) package, supplier device code EMD3F, this is a surface-mount part with a typical footprint around 1.6×1.6 mm. It suits compact portable or handheld designs where board area is tight. Available on tape and reel or cut tape — the reel option supports automated pick-and-place for volume builds.
