Littelfuse – How to choose the ideal sensor for industrial automation applications


By Gwenn Gmeinder, Sensors Business Development Manager, Littelfuse Motion-control and automation systems for industrial use have to cope with the hazards of dirt and dust commonly found in factory settings. In addition, conveyors and pick-and-place systems can be subject to vibration and shocks which threaten the stability of the control circuit’s sensors. The sensing technology […]

Littelfuse – TVS diode arrays protect DC lines in powered USB interfaces


Littelfuse has introduced a series of TVS diode arrays which provide ESD protection for DC power lines in powered USB interfaces. The new SP11xx series employs Zener diodes fabricated in a proprietary silicon avalanche technology to protect each I/O pin in the interface. These robust devices offer high surge tolerance. In fact, surge density per […]

Littelfuse – New SiC MOSFET combines low switching losses, high efficiency and robust performance


Littelfuse has introduced its first Silicon Carbide (SiC) MOSFET. The LSIC1MO120E0080 has a voltage rating of 1,200V and offers ultra-low on-resistance of 80mΩ. Total gate charge is typically 95nC. It is optimised for high-frequency switching applications: its combination of very low switching losses and fast switching speed is far superior to the performance provided by […]

Littelfuse – Compact varistors handle peak surge currents up to 10kA


Littelfuse has expanded its LV UltraMOVTM series of varistors to provide over-voltage protection to applications with very high DC voltage and surge requirements. Voltage surges may be induced by interference from indirect lightning strikes, system switching transients, and abnormal fast transients from a power source. Littelfuse’s varistors provide a compact and dependable form of protection […]

Littelfuse – SiC Schottky barrier rectifier outperforms conventional switching diodes


Littelfuse has introduced the LFUSCD series of Silicon Carbide (SiC) Schottky diodes, which offers high efficiency, reliability and thermal performance in power-switching applications. When compared to standard silicon bipolar power diodes, the LFUSCD series diodes produce lower switching losses, accommodate larger surge currents without thermal runaway, and operate at higher junction temperatures. These features enable […]

Littelfuse – Thyristors provide surge protection to high-speed data lines


Littelfuse offers a DSLP Biased series of thyristors which provides over-voltage protection for high data-rate communications links such as HD-SDI, HD-CVBS, VDSL2, ADSL2, ADSL2+ and with a minimal effect on data signals. The innovative design of the thyristors results in a capacitive-loading characteristic which is compatible with these high-bandwidth applications. This technology provides a […]

Littelfuse – The MLA series of small multi-layer TVS devices operate over a wide temperature range


The MLA series of Transient Voltage Suppressor (TVS) devices may be used to suppress a variety of transient events, including those specified in the IEC 61000-4-2 and other standards. Benefitting from Littelfuse’s multi-layer fabrication technology, the MLA series typically protects ICs and other components at the circuit-board level, for which it suppresses inductive switching and […]

Littelfuse – SDxxC Series: Automotive-qualified 450W TVS diode arrays protect low-speed I/Os

SD series TVS diode: same footprint as 0805 MLV

Littelfuse’s uni-directional 450W SD series and bi-directional SDxxC series general-purpose diode arrays, for Transient Voltage Suppression (TVS), are designed to replace the Multi-Layer Varistors (MLVs) commonly used for ESD protection. Their compact SOD-323 package fits the footprint of an 0805 MLV, allowing manufacturers to replace them in their designs with an SD or SD-C device […]

Littelfuse – SM24CANA Series and SM24CANB Series: TVS diode arrays offer high level of over-voltage protection on CAN bus lines


Two series of diode arrays for Transient Voltage Suppression (TVS) from Littelfuse enable designers to protect automotive CAN bus lines from damage due to ESD, Electrical Fast Transients (EFTs) and other over-voltage transients. The SM24CANA and SM24CANB series diode arrays can absorb repetitive ESD strikes above the maximum level specified in the IEC 61000-4-2 standard […]
