SMF5.0A

SMF5.0A is a unidirectional transient-voltage suppressor diode from Zhuhai HongJiaCheng in SOD-123FL, verified against the maker’s SMF SERIES manual, revision 2.2. The code decodes in the manual’s own part-numbering: the A suffix is the 5 % tolerance grade, the absent C marks the unidirectional form, and the package marking is AE. Verified figures for this row: a 5 V reverse standoff, breakdown between 6.4 V and 7.0 V at 10 mA, maximum clamping of 9.2 V at a 21.7 A peak pulse current, reverse leakage of 400 µA maximum and 200 W peak pulse power. The selection point is single-polarity clamping for a DC 5 V rail in the small SOD-123FL body — where the line never swings negative, the unidirectional form is the direct fit, and the bidirectional SMF5.0CA in this catalog is the form for lines that do. Selection advice: do not read the bidirectional leakage footnote onto this code — the doubling note in the manual applies to the CA parts only, and this page carries the table limit as printed. 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.
