Motorola Small–Signal Transistors, FETs and Diodes Device Data is a document about Motorola's small-signal transistors, FETs, and diodes. The document describes the features and characteristics of these miniature surface mount MOSFETs, including low rDS(on) value, high efficiency, and energy conservation. It is ideal for use in small power management circuits, such as dc-dc converters, portable and battery-powered products, etc.
