LED strings stay illuminated when a single one fails
Expanding the company’s portfolio of PLED Open LED protection devices, Littelfuse annonuce the release of the PLEDxUx unidirectional series open LED protector. The series is suited for applications including street, subway, and tunnel lights, aircraft/runway lights, outdoor signage and headlights.
Diode bridge for universal PoE applications up to 51W
The PD70224 IdealPoE diode bridge is a dual pack of MOSFET-based full-bridge rectifiers from Microsemi. Integrating low-RDS 0.16Ohm N-channel MOSFETS for much higher overall efficiency and higher output power, this power solution is suitable for use in powered devices for PoE and PoH (Power-over-HDBaseT) applications in the communications and enterprise markets, including wireless LAN access points, small cells and small switches/routers.
Minimize power & heat loss in PoE devices with new LT4321
The LT4321, an ideal diode bridge controller that replaces two diode bridge rectifiers with low-loss N-channel MOSFET bridges, has been launched today by Linear Technology. The LT4321 increases the available power and reduces heat dissipation in a PoE PD. The space- and power-efficient LT4321 dual active bridge rectifies and smoothly combines power from both the data and spare pairs into a single, polarity-correct supply output.
Vishay unveil 50V TMBS rectifiers for smartphone chargers
Vishay has today announced the industry's first devices to combine low forward voltage drop down to 0.40 V typical at 10 A and 0.41 V typical at 15 A with optimized leakage current in the slim TO-277A (SMPC) package for smartphone and tablet charger applications. The V10PN50 and V15PN50 are two new high current density 50 V TMBS Trench MOS Barrier Schottky rectifiers.
Vishay to participate in ESA's Space Passive Component Days symposium
Vishay will be participating in the European Space Agency's Space Passive Component Days symposium, at the European Space Research and Technology Centre in Noordwijk, South Holland. A supplier of passive components to the space market for over 30 years, Vishay will be exhibiting a wide variety of its leading resistors, tantalum capacitors, and inductors at the event in booth #12.
Reduce power loss with Vishay's new TMBS rectifiers
Vishay has today announced an expansion of its TMBS Trench MOS Barrier Schottky rectifiers with the introduction of 12 new 45 V, 60 V, and 100 V devices, featuring a wide range of current ratings from 6 A to 20 A. Featuring extremely low forward voltage drop in a surface-mount TO-252 (DPAK) package, the new TMBS rectifiers are optimised for use in commercial applications.
