ST’s power Schottky diodes combine low voltage-drop characteristics with negligible or zero recovery. They range from 15 to 200 V and from 1 to 240 A, so covering all application needs from OR-ing and 48 V converters, to battery chargers and welding equipment. They are avalanche specified for improved ruggedness.

The latest devices are 60 V, 80 V, 120 V medium VF and IR , and 200 V power Schottky diodes.

They feature a broad package offer, with through-hole and surface mount industry standard outlines, as well as the new PowerFLAT™ package, which is a step further in power density for 30 V and 45 V bypass diodes designed for solar panel junction boxes. The last package introduction from ST is the narrow-leaded TO-220AB package, particularly suited for use in semi-slim or slim-type notebook adapters. Thanks to its narrower lead shoulders, this package can be completely inserted inside the PCB. Power Schottky rectifiers rated at 60 V, 80 V, 100 V and 120 V are already available in this package, and more diodes are to come.

Only 1-mm thick, new Schottky diodes for lighter and slimmer power modules

Housed in the SOD123Flat and SOD128Flat packages – 1 mm thick only (12 and 26 mg) – ST’s 40, 60 and 100 V power Schottky rectifiers are tailored for miniature LED lighting, battery-powered equipment, power converters, motor drives and equipment installed in harsh industrial environments thanks to a T range from –40 to 175 °C.

Almost 60% thinner than the standard SMA package – while fully footprint compatible – designers can create lighter and slimmer modules or use these as replacements in existing designs, choosing to increase their application efficiency with the ‘L’ series featuring a low forward voltage drop, or pushing the limit of thermal runaway risk with the high-temperature ‘H’ series.
