SMBJ12CA

SMBJ12CA is the bidirectional row of the Littelfuse SMBJ transient-voltage suppressor series in DO-214AA (SMB), package marking BE, verified against the maker’s own series datasheet hosted on littelfuse.com; the bare code is the maker’s base order code, ordered without a packing suffix. Verified figures for this row: a reverse standoff of 12.0 V, breakdown of 13.30 V minimum and 14.70 V maximum at a 1 mA test current, maximum clamping of 19.9 V at a 30.2 A peak pulse current, reverse leakage of 1 µA maximum, and the series peak pulse power of 600 W on the 10/1000 µs waveform. The selection point is a 600 W bidirectional suppressor for 12 V rails in vehicles, industrial controls and power supplies. Selection advice: this catalog’s Littelfuse SMBJ12A is the unidirectional sibling — a different device, not a packing variant — and the SMBJ12CA designation is also documented by Ruilon and by Brightking (Junyao) in their own SMBJ manuals; the makers’ tables are not interchangeable, so state the maker in the RFQ. Parameters verified against the Littelfuse SMBJ series datasheet.
