Following investment in Monolith Semiconductor, Littelfuse has set out its roadmap for SiC and IGBT development. The company offers IGBT modules rated up to 1,700V and 600A which are suitable for industrial drives, UPS, solar inverters, EVs and welding machines.

For applications that demand efficiency, reliability and thermal management, such as solar inverters, EV/HEV charging station, industrial power supplies, industrial drives, welding and plasma cutting, Littelfuse has introduced the LFUSCD series of SiC Schottky diodes.

At PCIM Europe 2016 in Nuremberg from 10th to 12th May 2016, Littelfuse will be unveiling families of SiC Schottky diodes and silicon IGBTs in Booth 7-140. An in-booth demonstration will illustrate the capabilities of Monolith’s SiC MOSFET technology with a 5kW buck converter with 675V nominal input and 350V nominal output. The converter switches at high frequencies around 200kHz with an efficiency over 98% that cannot be achieved with sili...

William Shenberger, Field Application Engineer at Littelfuse, offers his tips for Designing LED Bulbs using transient and surge protection devices. Designers of early indoor LED light bulbs faced numerous technical hurdles, including AC to DC conversion, thermal heat sinking, constraints imposed by current bulb sizes, electrical transients, not to mention the basic challenge of driving the LEDs that produce the light.

Littelfuse has successfully completed its acquisition of the circuit protection business of TE Connectivity for $350m in cash. The circuit protection business has a prominent position in polymer-based resettable circuit protection devices, with a global presence in the automotive, battery, industrial, communications and mobile computing markets. The acquired business has operations in Menlo Park, California and manufacturing facilities in Tsukuba...

The Electronica China exhibition, held on 15th-17th March 15-17 in Shanghai, saw Littelfuse add a series of silicon Schottky devices designed for ultra-low forward voltage drop (VF) to its expanding power semiconductor portfolio.

Featuring crush ribs on the capsule that requires no attachment accessories for installation, Littelfuse has introduced the 59040 series press-fit reed sensor. This magnetically operated sensor is designed to press-fit securely into a 9.5mm (3/8”) diameter hole and offers another sensor option for the competitive reed sensor market. Its enhanced sensitivity allows for a wider air-gap between the sensor and its matching 57040 actuator.

Expanding its power semiconductor portfolio, Littelfuse has announced the MBR series Schottky barrier rectifiers (standard Schottky) and the DUR series ultrafast rectifiers. Designed to meet the general requirements of commercial and industrial applications, both series will be displayed at Electronica China, 15th to 17th March, 2016, in Shanghai, in Booth No. 3522 (E3 Hall).

Littelfuse has introduced the company’s first discrete thyristor devices capable of withstanding voltage spikes higher than 1,200V. The Littelfuse Teccor SK225xD/SK255KD/SK625xD/SK655KD series SCR switching thyristors are unidirectional switches designed to handle voltage spikes and power surges in incoming AC power mains.

Upscreened for use in aerospace, military, industrial and medical applications, two series of high reliability TVS diodes have been introduced by Littelfuse. The SMCG-HR and SMCG-HRA series devices are designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning surges and other transient voltage events.

As part of the company’s strategy to move more significantly into power semiconductors for industrial and automotive markets, Littelfuse has made an investment in Monolith Semiconductor, a start-up company developing silicon carbide technology.

Wherever sources of sparks or excess heat are present, substances such as gases, petroleum products and airborne dusts or fibres pose a serious risk of triggering an explosion and subsequent fire. To minimise these losses, regulatory bodies around the world have worked to refine standards that will mitigate the spark flash potential that can be found in these working environments. By Bharat Shenoy, Littelfuse.

Designers of today’s electronic devices have demanded more functionality with greater flexibility and higher levels of user interaction. These circumstances have helped in driving the development of nanometre chipsets along with a multitude of user interfaces or ports. The confluence of these two has made electronic devices more susceptible to ESD and required the need for a more robust solution.

Growth in demand for LED lighting is accelerating as consumers and industrial users seek more energy-efficient illumination options. Growth is also being driven by government actions designed to discourage continued usage of incandescent lamps. This means the high adoption rate of LED lighting is definitely a global phenomenon.
