Littelfuse Introduces SiC Schottky Diodes with Negligible Reverse Recovery, Enhanced Surge Capability, and Reduced Leakage Current

Ideal for applications that demand improved efficiency, reliability, and thermal management

CHICAGO — (BUSINESS WIRE) — May 10, 2016Littelfuse, Inc., the global leader in circuit protection, will introduce the latest addition to its growing line of power semiconductor products, the LFUSCD Series of Silicon Carbide (SiC) Schottky Diodes, at the PCIM Europe (Power Conversion and Intelligent Motion) 2016 exhibition, set for May 10-12, 2016, in Hall 7, Booth 140, Nuremberg Messe, Nuremberg, Germany.

When compared to standard silicon bipolar power diodes, LFUSCD Series SiC Schottky diodes allow designers to reduce switching losses, accommodate large surge currents without thermal runaway, and operate at higher junction temperatures, all of which enable substantial increases in system efficiency and robustness.

The merged p-n Schottky (MPS) device architecture of the LFUSCD Series ensures enhanced surge capability and reduced leakage current. Available in voltage ratings of 650V and 1200V at current ratings ranging from 4A to 30A, they are well-suited for a broad range of markets, including industrial power supplies, solar inverters, industrial drives, welding and plasma cutting, and EV/HEV charging stations.

LFUSCD Series SiC Schottky Diodes improve the efficiency, reliability, and thermal management of applications, such as:

  • Power factor correction (PFC).
  • Buck or boost stages in DC-DC converters.
  • Free-wheeling diodes in inverter stages (switch-mode power supplies, solar, UPS, industrial drives.)
  • High frequency output rectification.

“As part of our growing power semiconductor portfolio, we are excited to announce our line of SiC Schottky diodes,” said Dr. Kevin Speer, business development manager for the Power Semiconductor technology line. “With best-in-class forward voltage drop and stored capacitive charge, Littelfuse SiC diodes will enable our customers to optimize the efficiency of their designs while increasing system robustness and reliability.”

LFUS Series SiC Schottky Diodes offer these key benefits:

  • Best-in-class capacitive stored charge and near-zero reverse recovery make these devices suitable for high frequency power switching, ensure negligible switching losses, and reduce stress on the opposing switch.
  • Best-in-class forward voltage drop ensures low conduction losses.
  • Maximum junction temperature of 175°C provides for a larger design margin and relaxed thermal management requirements.
  • Merged p-n Schottky (MPS) device architecture enhances surge capability and provides extremely low leakage.


LFUS Series SiC Schottky Diodes are available in tubes in TO-220 two-lead and TO-247 three-lead packages. Sample requests can be placed through authorized Littelfuse distributors worldwide. For a listing of Littelfuse distributors, please visit
