Jiangsu Changjing Electronics (CJ) · Schottky rectifier · SOD-123
CJ 1 A, 40 V Schottky barrier rectifier in SOD-123, marked SL. LCSC lists it as "B5819W SL" (part number plus marking code). Typical uses: OR-ing power inputs, reverse-polarity and freewheel protection.
Verification
A person checks each page against its datasheet and signs it off here; the badge turns amber if a checked file changes.
