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. ## Lifecycle and compliance Listed as Active with ROHS3 compliance — no end-of-life notice, no RoHS transition risk.","metaTitle":"RB557WMTL ROHM Schottky Diode, 30V, 100mA, Common Anode","metaDescription":"ROHM RB557WMTL Schottky barrier diode, 30 V reverse, 100 mA average, common-anode pair.
