NXP launches 1006-size, 390mV Vf schottky rectifier for mobile devices
NXP Semiconductors N.V. has launched the PMEG2005BELD Schottky rectifier in an ultra-small and flat 1.0 x 0.6 x 0.37-mm plastic Surface Mount package DFN1006D-2 (SOD882D).
The 20-V, 0.5-A PMEG2005BELD Schottky barrier rectifier is claimed by NXP as the smallest in the market with a maximum forward voltage of 390 mV at 0.5-A forward current that offers increased battery life and performance. PMEG2005BELD Schottky rectifier feature a low reverse current of only 50 ľA at 10-V reverse voltage and hence can be used for backlighting displays in smartphones, MP3 players and tablet PCs.
Dr. Wolfgang Bindke, product marketing manager for diodes at NXP Semiconductors says "Board space inside today's smartphones is very limited. We designed this latest low-VF Schottky rectifier based on customer requests to put the characteristics of products two generations larger into a smaller 1006 (0402)-sized plastic package without sacrificing performance. As a result, we have set a new benchmark for low forward voltage in this small leadless package, offering 20 percent more efficiency than other products available in this size range. To achieve these excellent electrical parameters, we had to optimize the silicon wafer process and package assembly".
Key Features and Benefits as per NXP:
ˇ Robust and compact
ˇ Average forward current: IF(AV) = 0.5 A
ˇ Reverse voltage: VR = 20 V
ˇ Low forward voltage VF = 390 mV at 0.5 A forward current IF
ˇ Low reverse current IR = 50 ľA at 10 V reverse voltage VR
ˇ Qualified according to automotive standard AEC-Q101
ˇ Tin-plated, solderable side pads
ˇ Longer battery life due to reduced power consumption
ˇ High packing density onto the PCB due to form factor and excellent thermal conductivity
ˇ Permits small distance PCB stacks with high stack density, due to extremely low height of device (0.37 mm)
ˇ Allows optical inspection of solder joints due to tin-plated side pad of DFN1006D-2 (SOD882D) package
The PMEG2005BELD is currently available in mass quantities.
