## **FDC638APZ** 

## **P-Channel 2.5V PowerTrench[®] Specified MOSFET** 

## **–20V, –4.5A, 43m** Ω 

## **Features** 

Max rDS(on) = 43mΩ at VGS = –4.5V, ID = –4.5A 

Max rDS(on) = 68mΩ at VGS = –2.5V, ID = –3.8A 

Low gate charge (8nC typical). 

High performance trench technology for extremely low rDS(on). SuperSOT[TM] –6 package:small footprint (72% smaller than standard SO–8) low profile (1mm thick). 

RoHS Compliant 

## **General Description** 

This P-Channel 2.5V specified MOSFET is produced using ON Semiconductor’s advanced PowerTrench **[®]** process that has been especially tailored to minimize the on-state resistance and yet maintain low gate charge for superior switching performance 

These devices are well suited for battery power applications:load switching and power management,battery charging circuits,and DC/DC conversion. 

## **Application** 

DC - DC Conversion
