Circuit protection company, Littelfuse, has introduced a new series of small-footprint TVS Diode Arrays (SPA diodes) that are optimised for protecting high-speed signal pins. The SP3422-04UTG series 0.2pF 22kV TVS Diode Array integrates four channels of ultra-low capacitance rail-to-rail diodes and an additional zener diode to provide protection for electronic equipment that may be exposed to destructive electrostatic discharges (ESD).

Littelfuse has introduced a series of high-temperature SCR (silicon-controlled rectifier) thyristors, the first circuit protection devices of their kind to offer a junction temperature of 150°C in compact surface-mount D-PAK (TO-252) packaging. These devices are also available in through-hole V-PAK (TO-251) packages. Standard SJ Series SCR Thyristors have a low gate current trigger level of 6mA or 15mA maximum at approximately 1.5V.

Littelfuse has introduced two series of High Temperature Alternistor Triacs, the latest additions to the company’s thyristors portfolio. With a maximum junction temperature of 150°C, the 16A QJxx16xHx Series and 25A QJxx25xHx Series are designed for use as AC switches, helping circuit designers address overheating challenges in AC power control applications. Their high peak, single cycle AC current pulse ratings allow them to tolerate h...

  Circuit protection company, Littelfuse, has introduced its first series of silicon carbide (SiC) MOSFETs, the latest addition to the company’s growing power semiconductor line. The LSIC1MO120E0080 series, with a voltage rating of 1,200V and ultra-low (80mΩ) on-resistance, is the first organically designed, developed, and manufactured SiC MOSFETs to be released by this partnership.

  Littelfuse has introduced multiple series of high-voltage Fuse Blocks and Fuse Holders designed for mechanical installation of fuses. Developed for applications from 400V to 600V, these new series include several fuse mounting alternatives to accommodate the mechanical design of the application.

  Rethinking wafer fabrication and converter design can make SiC devices more affordable and accessible, advocate Corey Deyalsingh, Littelfuse and Sujit Banerjee, Monolith Semiconductor

The 16A silicon-controlled rectifier (SCR) switching thyristor series from Littelfuse is optimised for electric vehicle on-board charge (EVOBC) applications. The devices are claimed to offer "excellent" AC handling capability and surge robustness for input rectifiers.

  Compact AXGD series Xtreme-Guard ESD suppressors by Littelfuse can be used in automotive antennae, RF antenna systems and infotainment. The compact, surface mount, polymer automotive-grade suppressors are capable of protecting sensitive devices from contact/air discharges as high as 30kV.

Global circuit protection company, Littelfuse, has introduced a series of Schottky Barrier Rectifiers designed to outperform conventional switching diodes in commercial, industrial and automotive applications. DST Series Schottky Barrier Rectifiers combine ultra-low forward voltage drop, high current handling, high junction temperature capability, and low leakage performance in a compact TO-277B surface mount package.

Global circuit protection company, Littelfuse, has introduced a series of 40A standard high-temperature silicon-controlled rectifier (SCR) thyristors that are suitable for use as switches for rectifier and phase control applications such as voltage regulator, heating and motor speed controls. The new SJxx40x series is the first SCR thyristor from Littelfuse capable of handling 600V, 40Arms and junction temperatures up to 150°C.

It has been announced that Littelfuse has acquired the assets of U.S. Sensor. Headquartered in Orange, California, U.S. Sensor is a manufacturer of thermistors and probe assemblies used in the most demanding temperature sensing applications. Terms of the transaction were not disclosed. Deepak Nayar, Senior Vice President and General Manager, Electronics Business Unit, said: “U.S. Sensor expands our existing sensor portfolio i...

A series of TVS diode arrays have been introduced by Littelfuse, optimised to protect DC powerlines for PoweredUSB interfaces from damaging electrostatic discharges (ESDs). SP11xx series TVS diode arrays employ Zener diodes fabricated in a proprietary silicon avalanche technology to protect each I/O pin in the interface.

  Littelfuse has introduced the first encapsulated surface mount fuse designed for intrinsic safety protection of equipment intended for use in or near hazardous locations and explosive atmospheres and certified to the UL 913 Standard.

Littelfuse bringing a legacy of strength, security, and stability in circuit protection to the Power Semiconductor space.

Littelfuse has concluded their programme for the PCIM (Power Conversion and Intelligent Motion) Europe 2017 Exhibition. The highlight of this year’s exhibition was the introduction of the GEN2 Series of 1200V SiC Schottky Diodes featuring near-zero recovery time and low forward voltage for higher system efficiency. Samples are now available upon request via links on the SiC Schottky Diodes new products page.

Littelfuse has introduced a series of UL approved high current, surface mount fuses.
