LED lighting design guide
Littelfuse has created an interactive e-book as a resource for designers of LED residential retrofit lamps and outdoor luminaires. The Guide’s interactive features enable users to quickly find the answers to LED lighting design questions and review details whenever needed.
Designing proper circuit protection for wearables
As consumers become increasingly dependent on wearables, circuit designers are tasked with incorporating advanced circuit protection technologies that safeguard the device as well as the user. Without proper protection, the device’s sensor circuits, battery-charging interfaces, buttons or data I/Os could be irreparably damaged by ESD that is often caused by close interaction with the user.
Protect against ESD in fast-charging applications
Designed to provide superior ESD protection for current-intensive applications, such as fast-charging peripherals or PoweredUSB, the SP1255P series has been announced by Littelfuse. The low capacitance ESD protection TVS diode arrays integrate three channels of ultra-low capacitance steering diodes with a low voltage TVS diode to provide maximum ESD protection of the USB data and ID pins, according to the IEC 61000-4-2 standard.
Switches feature close-differential characteristics
Close-differential switches, suitable for applications with limited space, have been introduced by Littelfuse. The MACD-14 and MASM-14, which extend the company’s reed switch product line, are capable of switching 200VDC at up to 10W. Enabling accurate performance in all operating conditions, the devices feature a sensitivity range of 10-30AT.
Protect against load dump without expanding design footprint
A TVS diode, designed specifically to protect sensitive electronic equipment from voltage transients induced by load dump and other transient voltage events, has been released by Littelfuse. The SLD series TVS diode, which is AEC-Q101 qualified, offers a 5000W (10/1000μs) or 2200W (load dump) peak pulse power dissipation rating in a standard P600 package.

IGBT expands control with module size options
Modules rated up to 1700V and 450A extend Littelfuse’s IGBT power control semiconductor offering. The company now offers half-bridge, six-pack, and PIM modules in S, D, H, W, and WB packages. As well as standard offerings, customised versions can meet exact specifications in drives and motion control, solar inverters, UPS and SMPS, and welding machines.
Littelfuse exhibit SPD modules at electronica 2014
Littelfuse will be showcasing circuit protection technology, including a complete portfolio of semiconductor products at electronica 2014, which takes place from 11th to 14th November in Munich.
Survey reveals arc-flash safety is a priority
Arc-flash safety is a priority among plant professionals and protection technologies such as arc-flash relays are rapidly growing in popularity, it has been revealed. A survey, conducted by Littelfuse, found that while arc-flash danger was not a concern 10 years ago, 85% of the 825 respondents agreed or strongly agreed that arc-flash mitigation is important today.
TVS diodes target DC line protection in aviation electronics
Expanding its offering of high-reliability Transient Voltage Suppression (TVS) diodes available with customised upscreening and sorting process flows, Littelfuse has announced the SMBJ-HR and SMBJ-HRA series. Rated for 600W of peak pulse power dissipation, the diodes are suited for DC power protection and ESD protection in avionics applications.
Protecting patients and their medical equipment
Today, patients rely on a growing number of portable medical devices such as glucose meters, blood pressure monitors or defibrillators. But even a seemingly minor electrostatic discharge could easily render a portable medical device useless. To ensure safe, reliable performance of these devices, their designers should use best practices to factor in circuit protection requirements from the earliest stages of the circuit design process. By James C...
TVS Diode Arrays replace 0402 multilayer varistors
Designed to protect sensitive equipment from damage due to electrostatic discharge (ESD) and other overvoltage transients, the SPHV (unidirectional) and SPHV-C (bidirectional) series 200W discrete TVS Diode Arrays (SPA Diodes) have been introduced by Littelfuse.
Paying for the right protection
Once aware of the danger, design engineers can easily help reduce the risk of chip damage caused by user-induced overvoltage transients, such as ESD. By Phillip Havens, Principal Engineer, Littelfuse, and Chad Marak, Director of Technical Marketing and TVS Diode Array Products, Semiconductor Business, Littelfuse.
TVS Diode Array for harsh industrial environments
AEC-Q101 qualified to ensure maximum reliability in the harshest environments, the SM712 series TVS Diode Array (SPA Diodes) has been introduced by Littelfuse. It protects RS-485 applications with asymmetrical working voltages (from -7 to +12V) from damage due to electrostatic discharge (ESD), electrical fast transients (EFT), and lightning-induced surges.
