Power Schottky

ST power Schottky diodes combine low voltage-drop characteristics with negligible or zero recovery. Their voltage range spans 15 to 200 V and 1 to 240 A currents, and covers applications from low voltage OR-ing and 48 V converters, to higher voltage battery chargers and welding equipment.

Power Schottky high temperature
ST high-temperature power Schottky diodes like the STPS20H100 offer a junction temperature of 175°C and a voltage range of 60 to 170 V. These diodes offer the lowest leakage current and the best guard banding against thermal runaway, providing greater design headroom in terms of case temperature and leakage current. They’re ideal for applications such as compact 12/24 V converters that require high-voltage performance. All diodes in this product range have a maximum operating temperature of 175°C and are designated with an "H".

Power Schottky low VF
ST low VF power Schottky diodes are designed for applications requiring higher efficiency and are available from 15 to 120 V. These diodes offer the lowest forward voltage drop (VF) and are specified with a 150°C max. junction temperature. They excel in low voltage SMPS rectification with their 20-60 V range, and are ideal for applications such as OR-ing diodes in server applications, rectification in notebook adaptors, and freewheeling in desktop or industrial SMPS.

Main Schottky range:

ST Schottky diodes offer flexible package options in various through-hole and surface mount outlines. The new PowerFLAT package enables higher power density for 30 and 45 V bypass diodes, and is ideal for solar panel junction boxes. Power Schottky rectifiers rated at 60, 80, 100, and 120 V are now available in the narrow-lead TO-220AB through-hole package, which enables flush placement on a PCB and is ideal for slim-design notebook adapters.

The SOD123Flat, SOD128Flat, and PSMC packages are tailored for power Schottky rectifiers in slim equipment designs. These flat surface-mount packages are compatible with reflow soldering processes. They can be used in LED lighting, battery-powered equipment, consumer, and power converters in harsh industrial environments.

An excellent example is the STPS3170 with a 100-mV reduction in voltage drop and lower switching losses, which no bipolar diode can achieve. These features render this new 3 A 170 V SMA Flat Schottky diode ideal for high frequency and hot operating conditions, such as LED lighting.

Ultra Low Vf 100V Power Schottky Trench diodes

These 100V trench diodes are designed for both industrial and automotive applications. The package offer from SOD123Flat to DPAK provides flexible solutions while supporting higher power density designs and improve overall application performance. The product range includes AEC-Q101 qualified devices. Wide Tj operating range from -40°C to 175°C is fully compatible with the Automotive applications requirements. All packages achieves ECOPACK compliance.

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

Housed in the SOD123Flat, SOD128Flat – 1 mm thick only (12 and 26 mg) – ST’s 40, 60, 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 Tj range from –40 to 175 °C.
Almost 60% thinner than the standard SMA package – while 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.

In addition,  ST’s 40, 60, 100 V and 200V power Schottky rectifiers are now available in the new SMA Flat and SMB Flat packages providing even more power density in 1 mm thick only. They are fully compatible with SMA and SMB PCB footprints and even with SOD128 footprint.
