P-channel MOSFET offers increased power efficiency in space-critical applications
November 09, 2011 // Paul Buckley
Helping to increase battery efficiency and reduce board space, the miniature DMP1245UFCL 12V P-channel enhancement mode MOSFET from Diodes Incorporated has been introduced to meet the requirements of designers of space-starved portable products including smartphones and tablet computers.
The MOSFET is provided in the ultra compact and thermally efficient DFN1616 package and is characterized by a low RDS(on) that ensures conduction losses are kept to a minimum, thereby increasing battery life. For example, at 29 mΩ at VGS of 4.5 V the MOSFET’s on-resistance performance is 15% better than that of its closest rival, benefitting battery disconnect and general load-switching applications.
The DFN1616 has a typical off-board profile of 0.5 mm, making it 20% thinner than competitor equivalents, and occupies a PCB area of just 2.56 mm2, 55% of that occupied by alternative larger 2 mm by 2 mm packages.
DMP1245UFCL also offers users the advantage of an increase in protection against ESD. With gate protection specified at 3 kV, 50% higher than nearest equivalents, the MOSFET is highly resistant to the effects of human-borne ESD.
The miniature DMP1245UFCL 12V P-channel MOSFET from Diodes Incorporated is priced at $0.15 each in 3k quantities.

Internet of Things (IoT) manufacturer Ciseco has launched the Raspberry Pi ‘Wireless Inventors Kit’ (RasWIK), featuring 88 pieces to provide everything a Pi owner needs to follow a series of step-by-step projects or to create their own wireless devices, without the need for configuration or even writing code.
RasWIK has been designed to be highly accessible, demystifying the dark art of wireless and enabling anyone with basic computing skills to begin building wireless devices with a Raspberry Pi. You can create anything from a simple traffic light, to a battery monitor, or even a temperature gauge that sends data to the Xively IoT cloud so billions can access the data.This month, Ciseco is giving away twelve Raspberry Pi Wireless Inventors kits, worth £49.99 each for EETimes Europe's readers to win.
And the winners are...
In our previous reader offer, Farsens was giving away five kits for EEtimes Europe readers to evaluate its FenixVortex, Kineo and X1 wireless, battery free sensor tags.
Lucky winners include Mr A. Neil from the UK, Mr. E. Delvaux from Belgium, Mr Lengal from the Czech Republic, Mr H. Bijlsma from the Netherlands, and Mr G. Pfaff from Germany. All should be receiving their packages soon. Lets wish them some interesting findings with their projects.
