Micro Inverters

TVS diode arrays protect electronics from damage due to transient voltage surges and electrostatic discharges (ESDs). Littelfuse offers a variety of these surge protective devices (SPDs) in SOIC, DIP, flipchip, and other designs. Our lightning SPDs direct massive voltage surges from lightning strikes on outdoor equipment to ground. Our ultra-low capacitance TVS diodes provide ESD protection to data ports and cables. We also make SPDs specifically for automotive applications. Find your solution in our Circuit Protection Products Selection Guide.

Silicon Schottky diode rectifiers produce very low forward voltage drops while serving as ac switches in power converts and switched-mode power supplies. The devices can also be used to control the flow of current to other protection diodes. Littelfuse makes almost 100 types of silicon Schottky diodes. Consult our Power Semiconductor Product Catalog to find the best solution for your application.

Cartridge fuses provide overcurrent protection in agricultural, automotive, data center, industrial, power generation, and residential settings. Available with a broad range of ampere ratings, cartridge-type fuses also come in many sizes and types. The cartridge fuses for commercial and passenger vehicles, for instance, often come housed in color-coded thermoplastic cases. Solar power system cartridge fuses, however, resemble standard glass fuses. When selecting the type of cartridge fuse for your application, check the specifications for time-delayed, medium-acting, or fast-acting performance.

Littelfuse offers advanced gate driver ICs designed to optimize the switching performance of IGBTs, MOSFETs, and SiC-MOSFETs in power electronics. Our gate driver solutions include IGBT drivers and optically isolated gate drivers engineered for fast turnoff and high-efficiency control. Ideal for use in inverters, rectifiers, and other solid-state applications, our gate drivers ensure precise, reliable operation across demanding conditions.

Varistors provide transient voltage surge suppression in consumer electronics, household appliances, telecom equipment, and computers. The overvoltage protection devices shield semiconductors and other components from damage due to lightning strikes, and electrostatic discharges. Littelfuse produces metal oxide varistors (MOVs) in surface mount, thermally protected, and radial leaded configurations. In addition to AUMOV^®, UltraMOV^®, and TMOV^® devices, we design specialty varistors to customers’ specifications.

MOSFET modules combine fast recovery diodes with metal-oxide–semiconductor field effect transistors. The resulting solid state switches boast low-resistance and excellent dv/dt ruggedness. This makes the devices well-suited to performing high-speed switching operation while generating little noise or heat. Through its IXYS subsidiary, Littelfuse offers several types of MOSFET modules in single, dual, half-bridge, phase leg, triple phase leg, six-pack, and trench configurations.

Littelfuse offers a comprehensive range of silicon and silicon carbide MOSFETs engineered for high-efficiency current conversion, switching, and power factor correction (PFC). Our portfolio includes discrete power MOSFETs and MOSFET modules suited for rectifiers, inverters, and PFC circuits. With a wide selection of MOSFET packages and configurations, we provide both off-the-shelf and custom-designed solutions to meet the unique needs of industrial and commercial power systems.

Littelfuse offers a variety of discrete negative temperature coefficient (NTC) sensors and thermistors for temperature sensing, temperature measuring, and process control applications. Our NTC sensor and thermistor portfolio includes bare chip, epoxy-coated, glass-coated chip, and surface mount devices. All boast high accuracy, long-term reliability, stability, and predictable performance in challenging environments.

Transient voltage suppressor (TVS) diodes defend against damage from overvoltage events by responding within picoseconds to shunt current to ground. The classic example of TVS diode use is protecting outdoor telecom equipment from lightning strikes. Littelfuse produces surface mount and leaded diodes and TVS diode arrays for that, as well as TVS diodes for cars, personal electronics, data cables, and household appliances.
