SMF3.3A

SMF3.3A is the unidirectional row of the DOWO SMF transient-voltage suppressor series in SOD-123FL, verified against the parameter table on the maker’s own product page, where the row is printed as the pair SMF3.3A/SMF3.3CA — the A code is the unidirectional device and the CA code its bidirectional sibling in the same package. Verified figures for this row: a reverse standoff of 3.3 V, breakdown of 5.20 V minimum and 6.50 V maximum at a 10 mA test current, reverse leakage of 500 µA maximum, and maximum clamping of 8.8 V at a 22.7 A peak pulse current, in a series rated at 200 W peak pulse power. The selection point is a low-standoff suppressor for 3.3 V rails in the flat SOD-123FL body. Selection advice: the SMF designation is used by more than one maker — this catalog also lists HongJiaCheng SMF rows such as SMF5.0CA from that maker’s own manual — and the makers’ tables are not interchangeable, so state the maker in the RFQ.
