The SS54L with Schottky Barrier Diodes (SBD) SMB RoHS is a type of diode manufactured by LG Electronics Inc. It is a low-reverse recovery time rectifier with significantly lower forward voltage drop compared to traditional diodes. This type of diode uses a Schottky Barrier structure which is a P-N junction formed between a metal and a semiconductor material, resulting in a low forward voltage drop and, thus, low power consumption. It has an operating temperature range of -55°C to +150°C and a wide instantaneous forward current range of 0.02A to 0.5A. The SMB version of the SS54L diode is RoHS compliant, which means it conforms to regional regulations around the materials used in the device manufacturing.
