Description
SBAT54CWT1G is a dual Schottky barrier diode in a RoHS-compliant SMT package. The “C” typically indicates a common-cathode arrangement (two diodes share the cathode). It offers fast switching and a low forward voltage drop, making it suitable for high-efficiency power supplies, rectification, and polarity protection in compact boards. Typical ratings (per diode) are around 30 V reverse voltage and a few hundred milliamps forward current, with forward voltage about 0.2–0.4 V at rated current and very low leakage at normal temperatures. For exact values (VR, IF, VF, leakage, pinout, and package details), see the manufacturer’s datasheet for SBAT54CWT1G.
