New Littelfuse 1700 V SiC Schottky Barrier Diodes Offer Faster Switching, Higher Efficiency

August 16, 2021

Littelfuse, Inc., an industrial technology manufacturing company empowering a sustainable, connected, and safer world, recently announced the expansion of its silicon carbide (SiC) diodes portfolio to include the 1700 V-class. View the video.

The LSIC2SD170Bxx Series SiC Schottky Diodes are available in the TO-247-2L package with a choice of current ratings (10A, 25A, or 50A). They offer power electronics system designers a variety of performance advantages, including close-to-zero reverse recovery current, high surge capability, and a maximum operating junction temperature of 175°C, so they are ideal for applications that require enhanced efficiency, reliability, and simplified thermal management.

SiC Schottky barrier diodes are ideal in a wide range of AC/DC and DC/DC power converters for industry, energy generation, and energy distribution/storage, including:

- Industrial switch-mode power supplies,
- Uninterruptable power supplies,
- Battery chargers,
- Solar inverters,
- Industrial motor drives, and
- High speed rectifiers.

"Using SiC diodes in power designs instead of diodes based on legacy silicon-based technology helps designers develop more energy efficient power converters, saving energy and reducing costs related to cooling the power electronics," said Francois Perraud, Product Marketing Manager, SiC Products at Littelfuse. "They enable the design of faster switching power electronics in the converters which can then be made more compact at the same output power or pack more power in the same volume."

The LSIC2SD170Bxx SiC Schottky diodes offer these key benefits:

- Positive temperature coefficient of the forward voltage for safe operation and ease of paralleling
- Extremely fast, temperature-independent switching
- Dramatically reduced switching losses compared to Si bipolar diodes
- Optimized overall system efficiency

Availability

The LSIC2SD170Bxx SiC Schottky Diodes are available in the TO-247-2L package, in tube, with a minimum order quantity of 450 devices. Sample requests can be placed through authorized Littelfuse distributors worldwide.

Put to the Ultimate Test – Part 1: Torsion Tests by HELUKABEL

DCS Put to the Ultimate Test Part 1 Torsion Tests by HELUKABEL 1 400x275

Cables and wires in industrial robots and other moving machine parts are often required to withstand extreme stresses caused by torsion. Constant repetitive movements put materials under considerable strain. At the same time, operators expect components to function perfectly and reliably throughout their entire service life to avoid disruptions, outages and safety hazards.

For this reason, at HELUKABEL, we simulate intensive and continuous torsion stresses under realistic conditions with our high-tech testing equipment in Windsbach. We have several types of apparatus for doing this because some of our customers, for example those in the automotive industry, have very precise specifications for how a torsion test is carried out. The tests show that our cables and wires withstand speeds up to 1,000°/s, accelerations up to 2,000°/s² and torsion angles up to 720°. Hence, we make sure that each product always meets our customers’ high standards, and that they receive the impeccable quality they rightly expect from us as a leading supplier of cables, wires and accessories for more than 40 years.
