Littelfuse Featured Products


Littelfuse SPHV & SPHV-C TVS Diodes

Littelfuse SPHV & SPHV-C Series are TVS Diodes designed to protect sensitive electronic equipment against ESD and lightning-induced surge currents. SPHV (unidirectional) and SPHV-C (bidirectional) replace 0402-sized MLVs in automotive, LED, and instrumentation applications. These TVS diodes from Littelfuse absorb repetitive ESD strikes above the maximum level of the IEC61000-4-2 international standard (Level 4, ± 8kV contact discharge), as well as dissipate up to 8A of induced surge current.

LIttelfuse SP2574NUTG TVS Diode Array SPA™

Littelfuse SP2574NUTG TVS Diode Array protects against ESD (electrostatic discharge), CDE (cable discharge events), EFT (electrical fast transients), and lightning induced surges for high-speed, differential data lines. This low capacitance device in a µDFN package can protect up to 4 channels or 2 differential pairs. The "flow-through" design minimizes signal distortion, reduces voltage overshoot, and provides a simplified PCB design. SP2574NUTG from Littelfuse is ideal for high-speed 1GbE applications such as notebooks, switches, etc.

Littelfuse SP500x TVS Diode Arrays SPA™

Littelfuse SP500x is a highly integrated Common Mode Filter (CMF) providing both ESD protection and EMI common mode noise filtering for systems using high speed differential serial interfaces, such as MIPI D-PHY or HDMI. The series can protect and filter up to three differential line pairs. SP500x from Littelfuse is available in either a TDFN-10 or TDFN-16 package.

Littelfuse 4.0SMDJ TVS Diode

Littelfuse 4.0SMDJ TVS Diode is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. The 4.0SMDJ24A, a new alternative between industrial 3kW and 5kW TVS diode, is an ideal cost effective solution for designers.

Littelfuse LSP05 & LSP10 Surge Protection Modules

Littelfuse LSP05 and LSP10 Surge Protection Modules are the industry's first series connected, 20kA capable indicating surge arrestors for outdoor lighting applications. LSP05 and LSP10 SPD Modules are self-protected devices that can be used in outdoor and commercial LED lighting fixtures for transient overvoltage protection. LSP10 can provide up to 20kA protection module maximum lighting surge current and LSP05 provides up to 10kA. These Littelfuse devices are constructed with Littelfuse thermally protected varistor technology. The built-in thermal disconnect provides additional protection against catastrophic failure/fire hazard under varistor end-of-life or sustained overvoltage conditions. The LSP product series facilitates surge immunity compliance to IEEE C62.41.2 Location Category C High Exposure, ANSI C136.2, and US Dept of Energy MSSLC Model Spec.

Littelfuse PICO® 305 Series Fuses

Littelfuse PICO® 305 Series offers a range of encapsulated fuses approved under the UL913 standard for Intrinsically Safe Electrical Equipment to operate in hazardous locations. The 305 Series Fuse is ideal for use in the oil, gas, mining, chemical, pharmaceutical, food/beverage processing industries; it was designed to limit the energy and heat generated during its operation. The fuse design and its encapsulation are suitable for use in intrinsically safe apparatus and associated apparatus for voltages not exceeding 277V.

Littelfuse Dual IGBT Silicon Modules

Littelfuse dual IGBT silicon modules are ideal for applications including motor drivers, inverters, converters, and induction heating. The MG06400D-BN1MM features high short circuit capability, ultra low loss, high ruggedness, and is positive temperature coefficient. The MG12300D-BN2/3MM & MG06400D-BN4MM feature high short circuit capability, self limiting short circuit current, low switching losses, fast switching and short tail current, and the IGBT3 CHIP with trench plus field stop technology.

Littelfuse Fuses and Accessories

Littelfuse offers a comprehensive line of fuses, fuseholders, and fuse accessories for automotive, electronic, and industrial applications.

Littelfuse SE Series Gas Discharge Tubes

Littelfuse SE series GDT offers high surge ratings in a miniature package. It’s designed for surface mounting on PCB with a small size of 3.2x1.6x1.6mm. Low insertion loss is perfectly suited to broadband equipment applications. The capacitance does not vary with voltage, and will not cause operational problems with ADSL2+, where capacitance variation across Tip and Ring is undesirable. These devices are extremely robust and are able to divert a 500A-600A pulse in a miniature package 1206 without destruction.
