SMF15CA

SMF15CA is a bidirectional transient-voltage suppressor diode from Zhuhai HongJiaCheng in SOD-123FL, package marking IM, verified against the maker’s SMF SERIES manual, revision 2.2. Verified figures for this row: a 15 V reverse standoff, breakdown between 16.7 V and 18.5 V at 1 mA, maximum clamping of 24.4 V at an 8.2 A peak pulse current, reverse leakage of 1 µA maximum, and 200 W peak pulse power. The leakage line is deliberately the plain table figure: the manual’s doubling footnote applies only to bidirectional parts at a standoff of 10 V or below, and at 15 V this code does not qualify — a distinction that matters when this page is read next to the 5 V and 6.5 V SMF rows in this catalog, whose ceilings are the doubled ones. Selection advice: the 15 V standoff suits 12 V-class rails with charging headroom; confirm the 24.4 V clamp still clears the downstream absolute maximum before adopting the code. Note on attribution: the candidate pool labelled this line R+O (HongJiaCheng); the figures here are HongJiaCheng’s own, from its SMF SERIES manual — the R+O brand attribution is flagged for confirmation at review. Parameters verified against the HongJiaCheng SMF SERIES datasheet, revision 2.2.
