B5819W

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.

Loads on click. Unloads only if this page sits in the background.

Pinout

Pin Name Type Function
1 K passive Cathode, the end with the marking bar (datasheet p.1).
