Littlefuse Introduces New 1200V SiC Schottky Diodes

Littelfuse, Inc. added 1200V Schottky Diodes to its portfolio of silicon carbide (SiC) power semiconductor devices. Specifically, the company introduced five new GEN2 Series 1200 V, 3L TO-247 Schottky Diodes and three GEN2 Series 1200 V, 2L TO-263 Schottky Diodes.

The company says that when compared with silicon devices, GEN2 SiC Schottky Diodes drastically lessen switching losses and allow for a considerable increase in the efficiency and robustness of power electronics systems. Littlefuse introduced the new products during the PCIM 2018 Europe exhibition in Nuremberg.

The company points out that SiC power electronics offer higher efficiency than silicon devices and provides multiple advantages when designers use them in electric vehicle chargers, renewable energy systems, and data center power supplies. Also, the company notes that because the GEN2 SiC Schottky Diodes dissipate less energy and can operate at higher junction temperatures than many alternative solutions, they require smaller heat sinks. Smaller heatsinks can translate to a smaller system footprint.

Over, Littlefuse says that end-users will benefit from more compact, energy-efficient systems and a potential lower total cost of ownership.

Typical Applications for 1200V SiC Schottky Diodes

Typical applications for GEN2 1200V Schottky Diode Series include power factor correction (PFC), buck/boost stages in DC-DC converters, free-wheeling diodes in inverter stages (switch-mode power supplies, solar, UPS, industrial drives), High-frequency output rectification, and electric vehicle (EV) charging stations.

“These GEN2 SiC Schottky Diodes in 3L TO-247 and 2L TO-263 packages complement the 1200 V SiC MOSFETs and other GEN2 1200 V SiC Schottky Diodes already available from Littelfuse,” said Michael Ketterer, global product marketing manager, Power Semiconductors, Semiconductor Business Unit at Littelfuse. “We continue to strengthen our broad product portfolio, which, after the acquisition of IXYS, positions Littelfuse as a Tier 1 supplier for power semiconductor devices.”

Availability

GEN2 Series SiC Schottky Diodes are available in TO-263-2L and TO-247-3L packaging in tubes in quantities of 450. Littelfuse distributors worldwide can make samples available.
