Littelfuse has introduced an ultra-low capacitance protection thyristor, the SDP Series SIDACtor Protection Thyristor in the SOT23-6 package, providing robust overvoltage protection for broadband/xDSL telecommunications equipment with minimal effects on connection speed and reach. Patent-pending silicon crowbar technology allows for 45 percent lower capacitance than clamping devices like transient voltage suppressor diodes.

Why design engineers need to think about circuit protection as part of the design process, rather than as an afterthought. Bharat Shenoy, Director of Technical Marketing, Electronics Business Unit, Littlefuse, explores this view in this article from ES Design magazine.

Littelfuse unveil that it has developed in cooperation with leading photovoltaic equipment providers a Series of 1500 VDC photovoltaic fuses designed to protect the next generation of solar installations. The SPXV and SPXN Series of fuses meet the tough requirements of 30kA interrupt ratings, 1500 VDC protection and global standards critical to solar equipment manufacturers.

Littelfuse launches SRDA3.3 Series TVS Diode Array. The SRDA3.3 Series integrates low-capacitance steering diodes with an additional zener diode to protect data lines against electrostatic discharge and high surge events. The SRDA3.3 Series devices provide 40 percent greater protection without performance degradation than other available solutions.

Littelfuse has introduced the SP3051-04HTG Transient Voltage Suppression Diode Array (SPA Diode), the latest addition to the lightning surge devices in the company’s TVS Diode Array line. It integrates low capacitance rail-to-rail diodes with an additional zener diode to protect I/O pins against ESD and lightning-induced surge events.

Littelfuse announced the SB6100 Series Industrial Shock-Block, the first and only ground fault circuit interrupter device to meet UL 943C Class C and Class D requirements. Until now, GFCI devices have not been practical in industrial settings. Thanks to higher trip level standards and advanced filtering technology, industrial workers can finally be protected against dangerous electric shock.

Littelfuse has introduced the Kxxx1GL Series Multipulse SIDAC, a thyristor power control device designed for use in 220-240V AC line installations. The thyristor, when coupled with a capacitor and transformer, generates the multiple high voltage pulses required to ignite metal-halide lamps.

Littelfuse today announced it has signed a definitive agreement to acquire Hamlin, Inc. from Key Safety Systems for $145 million in a cash transaction. Hamlin is dedicated to providing sensor technology to the automotive industry as well as the electronics and industrial markets.

Littelfuse has introduced the SR05 Series TVS Diode Array – SPA Diodes, designed to protect telecommunication and industrial equipment against electrostatic discharge and lightning-induced surge events.

Littelfuse has introduced the SRDA05 Series of TVS SPA Diode Arrays. The SRDA05 Series is designed to protect telecommunications data lines against electrostatic discharge (ESD) and high surge events, providing a 20 percent higher power and surge handling capability than competitive devices on the market.

Littelfuse, Inc has introduced the Q6008LH1LED and Q6012LH1LED Series of Alternistor Triac and Q6008LTH1LED and Q6012LTH1LED Series of QUADRAC Thyristor Power Control Devices. These devices are designed for use as the switch in a dimmer circuit to adjust the light output of Light Emitting Diode (LED) bulbs and strings. They allow designers of AC line based dimmers for LED lighting to accommodate a wide range of operating parameters without sacrif...

Littelfuse has introduced the PICO 259-UL913 Series Intrinsically Safe Fuse, the first and only Fuse to be certified under the latest revision of the UL913 Safety Standard for Intrinsically Safe Apparatus and Associated Apparatus for Use in Class I, II, and III, Division 1, Hazardous (Classified) Locations.

Littelfuse has introduced the LV UltraMOV Series of low voltage, high surge current, radial leaded varistors. They provide an ideal circuit protection solution for lower DC voltage applications by offering higher surge ratings than ever before available in such small disc sizes.

The new EL3100 Ground Fault Indication System from Littelfuse indicates the presence of ground faults on ungrounded three-phase electrical systems while protecting operators from shock hazards. Because ungrounded electrical systems continue to operate in the presence of a ground fault, they can expose personnel to dangerous electric shock.

Littelfuse today announced the launch of its recently redesigned website, www.littelfuse.com, in German and Japanese. The English and Chinese versions of the website were released in July, with a fresh new look, updated content and improved functionality.

Littelfuse has released the 450W SD05 (unidirectional) and SD05C (bidirectional) Series General-purpose TVS Diode Arrays (SPA Devices), which are designed to replace multilayer varistors for protecting electronic equipment from damage due to electrostatic discharge and other transient events.

Littelfuse, Inc has introduced the TPSMA6L Series of Transient Voltage Suppression (TVS) Diodes. This new series can provide secondary transient voltage protection from transients induced by load dump and other transient voltage events for automotive electronic control units, sensors, entertainment systems, and other applications that require high reliability. This SMA device’s low profile DO-221AC package is less than 1.1 mm high, but it o...

Littelfuse has released the 808 Series TE5 Fast Acting Subminiature Fuse. This 250VAC/450VDC-rated fuse is designed to protect components or internal circuits against overcurrent conditions, particularly in high voltage DC applications, such as DC power supplies. Its high interrupt rating/breaking capacity (up to 10kA@450VDC) ensures it will open safely under high fault currents.

Littelfuse has expanded its SP1005 and SP1007 Series General Purpose TVS Diode Arrays (SPA Devices) with two new 0402 size devices designed to offer modern integrated circuits better protection from electrostatic discharge.

Littelfuse has developed the Nano2 485 Series Fuse, a compact, surface mountable 600VDC fuse for overcurrent protection of high voltage DC circuits. The Nano2 485 Series Fuse packs a high voltage and energy protection capability in a very small footprint.
