(Pack of 10) SS54 SMB 40V 5A Schottky Diode SMD Package DO 214AC

(Pack of 10) SS54 SMB 40V 5A Schottky Diode SMD Package DO 214AC

The SS54 is a 5A, 40V Schottky barrier rectifier diode available in the SMB (DO-214AC) surface-mount package. Known for its very low forward voltage drop and fast switching characteristics, it is widely used in high-efficiency power supplies, DC-DC converters, and reverse polarity protection circuits.

Compared to the SMC package version, the SMB package is smaller, making it suitable for compact and medium-power SMD designs while still offering excellent thermal performance and reliability.
