SiC Schottky diodes shrink energy costs and space requirements

SiC Schottky diodes shrink energy costs and space requirements
Littelfuse has introduced an expanded portfolio of silicon carbide (SiC) power semiconductor devices with the addition of five GEN2 Series 1200V, 3L TO-247 Schottky Diodes and three GEN2 Series 1200V, 2L TO-263 Schottky Diodes. When compared with silicon devices, GEN2 SiC Schottky Diodes reduce switching losses and allow for increases in the efficiency and robustness of power electronics systems. The product introduction was made during the PCIM 2018 Europe exhibition in Nuremberg.

Robust clip-attach package design supports mechanical durability

Robust clip-attach package design supports mechanical durability
Littelfuse has upgraded its switching thyristor line with the introduction of the SJ Series High Temperature SCR (Silicon-Controlled Rectifier) Switching Thyristors. This new series offers circuit designers blocking voltages (VDRM) up to 600V and current ratings from 4-40A to support a wide range of applications. By offering designers a wider operating margin than earlier SCRs, they make it possible to tolerate insufficient cooling and higher inrush currents at startup.

Automotive-grade TVS diode arrays ensure maximum reliability

Automotive-grade TVS diode arrays ensure maximum reliability
Littelfuse has introduced two series of AEC-Q101-qualified TVS Diode Arrays (SPA Diodes) designed to provide options for very fast acting, high performance over-voltage protection devices. The AQHV and AQHV-C series are designed to provide very fast acting, high performance over-voltage protection devices well suited for power interfaces, passenger charging interfaces, and well as LED lighting modules, and low speed I/Os.

Compact cartridge fuses save space on crowded boards

Compact cartridge fuses save space on crowded boards
Littelfuse has introduced the smallest cartridge fuse series available that’s rated at 500VAC with current ratings from 40-63A and a 2,000A at 500VAC interrupting rating. The 606 Series high current Cartridge Fuse is designed for overcurrent protection in applications such as high voltage power supply circuits rated up to 23kW. With a 10x32mm cartridge body, a single 606 fuse requires less board space than previous designs that used multiple lower current rated fuses in parallel.

Rice cooker lid lock features position sensing reed switches

Rice cooker lid lock features position sensing reed switches
Electric rice cookers are popular appliances that are used for cooking rice. These are pressure cookers that rely on a properly sealed compartment which maintains a high pressure. The pressure built up within the rice cooker compartment can be high enough to blow open the cooker lid if the lid is not properly locked in place when closed. The position sensing lid lock ensures that the lid is securely locked in place.

SiC MOSFETs feature ultra low on resistance at APEC 2018

SiC MOSFETs feature ultra low on resistance at APEC 2018
Littelfuse has added two 1,200V Silicon Carbide (SiC) n channel, enhancement-mode MOSFETs to their expanding first-generation portfolio of power semiconductor devices. These new SiC MOSFETs are the latest products of a strategic partnership that Littelfuse formed with Monolith in 2015 to develop power semiconductors for industrial and automotive markets. The announcement was made in the Littelfuse booth at the Applied Power Electronics Conference & Exposition (APEC 2018).

High power semiconductor crowbar protector for AC power lines

High power semiconductor crowbar protector for AC power lines
  AC power line disturbances are the cause of many equipment failures. The damage can be as elusive as occasional data loss or as dramatic as the destruction of a power supply, LED lightings, industrial system and consumer equipment such as ovens or refrigerators and television sets.

Protecting rechargeable Li-batteries in portable electronics

Protecting rechargeable Li-batteries in portable electronics
Littelfuse offers designers several protection devices to choose from in an array of form factors and device characteristics that meet the needs of their particular design. As sleeker designs and thinner portable consumer electronics become increasingly popular, Lithium-ion and Lithium- polymer batteries have become the 'go-to' power sources of choice in these applications.

Low resistivity PPTC to improve Li-ion polymer battery packs

Low resistivity PPTC to improve Li-ion polymer battery packs
Lithium-ion batteries (LIB) have now become part of the standard battery pack of choice used in most notebook, smartphone, e-reader, and tablet designs. The LIB chemistry produces optimal characteristics with regard to high energy density, low self-discharge, light weight, long cycle life, lack of memory effect, and low maintenance. LIBs are now gaining popularity in other market segments such as electric vehicles, power tools, and military/aerospace applications.
