Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductors system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore ( ), the underscore ( ) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore ( ). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild questions onsemi.com.

Many known Low r 80V Rated MOSFETs DS(on) bridge rectifier circuits can be configured using typical diodes. Maximizing Available Power and Voltage The conventional diode bridge has relatively high power loss that Eliminating Thermal Design Problems is undesirable in many applications. Especially, Power over IEEE802.3at Compatible Ethernet (PoE) Power Device (PD) application requires high-effi- ciency bridges because it should be operated with the limited - Meet Detection and Classification Requirement power delivered from Power Source Equipment (PSE) which is - Work with 2 and 4-pair Architecture classified by IEEE802.3at. FDMQ8205 is configured with low - Small Backfeed Voltage r dual P-ch MOSFETs and N-ch MOSFETs so that it can re- DS(on) duce the power loss caused by the voltage drop, compared to the Compact MLP 4.5x5 Package conventional diode bridge. FDMQ8205 enables the application to Applications maximize the available power and voltage and to eliminate the thermal design problems in PoE PD applications. Power over Ethernet (PoE) Power Device (PD) TM FDMQ8205 GreenBridge 2 is compatible with IEEE802.3at - IP Phones PoE standard by not compromising detection and classification - Network Cameras requirement as well as small backfeed voltage. - Wireless Access Points - Thin Clients - Microcell - Femtocell Package Marking and Ordering Information Device Marking Device Package Reel Size Tape Width Quantity FDMQ8205 FDMQ8205 MLP4.5x5 13 12 mm 3000 units 1 2016 Fairchild Semiconductor Corporation www.fairchildsemi.com FDMQ8205 Rev.1.2
