Diodes Incorporated Introduces Industry Smallest Bridge Rectifier for Power-Over-Ethernet Applications

DALLAS—(BUSINESS WIRE)—October 28, 2008— Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete and analog semiconductor markets, today announced the first in a series of small signal SBR® bridge rectifiers, targeting Power-over-Ethernet (PoE) and LED lighting applications. The SBR05M100BLP is the industrys smallest 0.5 Amp bridge in a 3.0mm x 3.0mm leadless package, providing high power dissipation in the smallest footprint available for end-user applications such as Internet Protocol (IP) phones, routers, and LED lighting equipment.

The SBR05M100BLP integrates four highly efficient SBR® diodes into one single package, eliminating the need to use four separate individual packages in a bridge configuration. It features a tiny footprint of 9mm2 total physical area, which is 52% smaller in total dimension area and uses 67% less board space than other standard traditional packages such as the HD-DIP case. The SBR05M100BLP also features a very low profile height of 0.6mm, making it ideal for continual reduction of thinner and more portable applications.

The SBR05M100BLP is used in applications requiring a full wave bridge rectifier to convert low voltage AC power signal to a usable DC signal for power devices. It offers a low typical forward voltage drop (VF) of 0.67V at 0.5A rated current at 25oC, providing additional power savings for todays energy efficient devices. In a standard application like a PoE device, the AC signal is directly supplied from the RJ45 Ethernet cable and is rectified through a bridge rectifier to a DC signal that can be used to power the device. This eliminates the need for bulky external power supply or adapter to power up the PoE device.

The SBR05M100BLP achieves a continuous forward current up to 0.5A with ultra-low reverse leakage and a high forward surge capability for improved reliability. The new SBR® bridge rectifier is rated from an operating temperature of 55oC to 150oC. Versions of the SBR® bridge rectifiers at 40V and 60V are currently in development and will be introduced later this year.
