4-4 Schottky Barrier Diodes (SBD)
¢ Overview
This series of 3 A to 5 A Schottky barrier diodes use a newly developed thin package and are ideal for on-board power
supplies or secondary-side rectifiers. The TMP package uses our company’s original wireless structure, providing high surge
withstand levels. The lineup that we have developed, can meet a wide range of needs and includes products with low VF,
products with low IR, and balanced type products with both low VF and low IR.
