Custom solutions for all your needs
Explore our extensive range of Littelfuse power semiconductor and integrated circuit technologies, available in both industry-standard and innovative packaging. We provide tailored, application-specific solutions to ensure your stringent requirements are met.
Power Semiconductors
Power Modules
Our diode and thyristor modules are optimized for power control applications, featuring low thermal impedance, high overload capacity, minimal current leakage, and low forward voltage drop. They are designed for simple bolt-down installation, providing full pressure contact for enhanced efficiency. These modules are commonly used in rectifiers, AC-DC converters, and AC switches for applications like induction heaters, electric motors, and lighting controls.
IGBTs (Insulated-Gate Bipolar Transistors)
These are utilized as current converters, solid-state switches, and protection devices across numerous applications. Littelfuse, along with its IXYS subsidiary, offers the widest range of discrete IGBTs and modules, suitable for inverters, rectifiers, and various protection mechanisms.
MOSFETs (Silicon/Silicon Carbide)
These transistors manage current conversion, switching, and power factor correction, serving critical roles in a vast array of applications. We supply both standard and custom MOSFET solutions to meet specific needs in rectifier, inverter, or PFC circuits.
Power Diodes
Designed for power supply applications, our diodes are characterized by low reverse recovery times, low forward voltage drops, and minimal leakage. They are ideal for DC-DC converters, induction heaters, and ultrasonic devices, with our Schottky diodes particularly suited for electric vehicles.
Thyristors (SCR & TRIAC)
These components serve as switches and overvoltage protectors. Littelfuse provides various SCRs, TRIACs, and Quadracs, along with DIACs for gate triggering, suitable for controlling motor speed, lighting, and heaters.
Integrated Circuits
Gate Drivers
Enhance the performance of power semiconductors with our gate driver ICs, which control IGBTs, MOSFETs, and SiC-MOSFETs. Our range includes patented, optically isolated drivers for applications needing quick turnoff capabilities.
Other ICs
Our portfolio includes digital bus drivers, optocouplers, error amplifiers, high-voltage analog switches, voltage monitors, and programmable capacitors, with specific designs for telecommunications.
Solid State Relays
OptoMOS® Relays
These offer fast, reliable switching without bounce, ideal for high-load AC systems. They come in compact designs for PCB mounting with low heat sink requirements, serving as excellent alternatives to traditional relays.
Stacks, Subsystems & Assemblies
We offer integrated solutions where power semiconductors, diodes, and thyristors are combined into efficient, pre-assembled units. These stacks often function as rectifiers or inverters, equipped with cooling fans and protective fuses. We also provide various accessories to support these assemblies and offer custom design services for unique requirements.
Littelfuse products are engineered to deliver reliability and performance, ensuring your applications are powered by cutting-edge technology.
