Littelfuse introduced an industry first: a new series of three unidirectional TVS diode arrays in space-saving 01005 flip chip packages (0.230mm x 0.430mm). Unidirectional protection is typically preferable to bidirectional protection, particularly on logic and data lines, which typically do not transit zero volts during standard operation.

Littelfuse has introduced what it claims to be the smallest (5.0×5.0×4.2mm) squared Gas Discharge Tube (GDT) with a 5kA surge capability and a ≤0.7pF off-state capacitance value available in the market today. The SH series GDT is designed to provide high levels of protection against fast-rising transients caused by lightning disturbances.

Surge protection modules designed to meet the needs of commercial and LED lighting.

A varistor series has been introduced by Littelfuse that is designed for high power applications and can operate at ambient temperatures up to 125°C with 2,500V isolation voltage. The HMOV Varistor Series’ high operating temperature is an advance made possible through the use of a silicone coating technology.

At electronica 2016 Electronic Specifier Editor Joe Bush caught up with Dieter Roeder and Juergen Scheele, Senior Vice President and GM, and Vice President respectively, of Littelfuse’s Automotive Business Unit, about how the company’s experience in this sector is playing a key role as electronics become increasingly integral in automotive applications.

Prior to the electronica exhibition in Munich, Electronic Specifier Editor Joe Bush caught up with Dr. Boris Golubovic, Vice President of Marketing and Strategy, Electronics Business Unit, Littelfuse, to discuss the company’s focus at the show and how it is tackling the challenge of the Internet of Things (IoT).

A 600VDC ceramic body fuse has been introduced by Littlefuse - the 507 Series Cartridge Fuse has an interrupting rating of 150A at 650VDC in a 6x32mm package. Its high DC voltage rating, combined with current ratings from 1-8A, make it suitable for over-current protection in high-voltage DC power circuits. 

  A series of TVS diodes has been introduced by Littelfuse. They have been designed specifically to protect sensitive portable and compact electronics from voltage transient events. 

A high voltage, surface-mount gas discharge tube (GDT) with two squared terminals has been introduced by Littelfuse. It is capable of withstanding surge currents of 3kA@8/20μs in a small form factor. CG4 series two-terminal high voltage miniature GDTs are high voltage (800-3,000V) devices designed for over-voltage protection for high isolation applications.

A series of thermally protected surge protective devices that provide robust transient overvoltage protection for outdoor and commercial LED lighting fixtures has been introduced by Littelfuse. The LSP05GI series LED Lighting Surge Protection Module is capable of providing 10kV/5kA surge protection and is certified to IEC/EN 61643-11. 

Littelfuse introduced the MG12600WB-BR2MM Series, the latest addition to its IGBT Module Power Semiconductor portfolio. The new 1200V, 600A Half-Bridge IGBT Module Series offers designers a substantially higher current rating than the portfolio’s previous maximum current rating (450A), offering the high efficiency and fast switching speeds of modern IGBT technology in a robust and flexible format.

Littelfuse has introduced a series of SIDACtor protection thyristors in DO-214AB (surface-mount) packages. The Pxxx0S3NLRP series provides robust surge protection performance at up to 2.5kA, while maintaining much lower switching threshold and on-state voltage than traditional protection solutions like Gas Discharge Tube (GDT) technology. They also offer crowbarring power fault protection superior to typical clamping devices.

Two series of TVS Diodes designed specifically to protect sensitive electronic equipment from voltage transients induced by load dump and other transient voltage events has been introduced by Littelfuse. The AEC-Q101 qualified TP1.5KE and TP5KP series Automotive Transient Voltage Suppression (TVS) Diodes offer a choice of 1500W (TP1.5KE) or 5000W (TP5KP) peak pulse power dissipation ratings in standard DO-201 and P600 axial-lead packages respecti...

Littelfuse has entered into definitive agreements to acquire the product portfolio of Transient Voltage Suppression (TVS) diodes, switching thyristors and Insulated Gate Bipolar Transistors (IGBTs) for automotive ignition applications from ON Semiconductor for a combined purchase price of $104m. This portfolio has annualised sales of approximately $55m. The transactions are expected to close in late August, 2016.

Designed to protect electronic equipment that may experience destructive ESD, Littelfuse has introduced the SP814x series of low capacitance TVS diode arrays. The devices integrate four or six channels of ultra-low-capacitance rail-to-rail diodes and an additional zener diode to safely absorb repetitive ESD strikes above the maximum level specified in the IEC61000-4-2 international standard (±8kV contact discharge) without performance degr...

Littelfuse has introduced two series of low capacitance TVS diode arrays optimised for protecting the NFC circuits of smartphones, tablets and other portable communication products from ESD damage. The SP3118 and SP3130 series TVS diode arrays include back-to-back TVS diodes fabricated in a proprietary silicon avalanche technology that absorb repetitive ESD strikes safely up to the maximum level specified in the IEC61000-4-2 international standar...

Littelfuse has introduced two series of TVS diode arrays (SPA diodes) designed to safeguard many of the latest high-speed interfaces from damage due to ESD. The SP7538P series TVS diode arrays integrate eight channels of ultra-low capacitance rail-to-rail diodes and an additional Zener diode in a µDFN-9 package. The SP0544T series TVS diode arrays have a similar design but are smaller, with four channels of ultra-low capacitance rail-to-rai...

Littelfuse has introduced a series of AEC-Q101 qualified TVS diodes designed to protect sensitive automotive electronic equipment from voltage transients induced by load dump and other events. The TPSMF4L series diodes offer 400W of peak pulse power dissipation in a compact, surface mount, flat-lead SOD-123FL plastic package with a low profile of just 0.98mm.

Two new series of miniature surface-mount two-terminal Gas Discharge Tubes (GDTs) designed to protect sensitive electronics from low-to-medium level lightning-induced surges and other voltage transients have been introduced by Littelfuse.

Protecting sensitive electronic equipment from ESD damage, the SP1026 series 15pF 30kV bidirectional discrete TVS diode array has been unveiled by Littelfuse.These robust general-purpose diodes can safely absorb repetitive ESD strikes at ±30kV (contact discharge, IEC 61000-4-2) without performance degradation and can safely dissipate 5A of 8/20μs surge current (IEC61000-4-5) with very low clamping voltages.
