New Dual Pch MOSFETS from Toshiba Combine Two Transistors in One Package

July 19, 2011

New Series Offers Industry's Lowest On-Resistance

IRVINE, Calif., — Toshiba America Electronic Components, Inc., (TAEC)* has announced the addition of the SSM6P47NU and SSM6P49NU to its lineup of small signal MOSFETS. Ideal for charging circuits for mobile devices, these dual Pch MOSFETS feature the lowest on-resistance in the industry when compared to equivalent packages.

From mobile phones and game consoles to digital cameras, power consumption and physical size are key considerations in the design of mobile devices. Toshiba's SSM6P47NU and SSM6P49NU address these issues by combining two independent transistors into one package.

A 1.8V drive, combined with a 4A drain current and extremely low on-resistance allow the SSM6P47NU and SSM6P49NU to run at a high rate of efficiency, which enables batteries to be fully charged in less time. Available in a UDFN6 package (2.0 x 2.0mm), these dual MOSFETs are a suitable size for charging circuits and are capable of acting as a switch to control which loads are connected or disconnected from the circuit.

Features of the SSM6P47NU and SSM6P49NU include:


VDSS = -20V
VGSS = ±8V
ID = 4A
RDS (max)@(VGS =-1.5V) = 242mΩ
RDS (max)@(VGS =-1.8V) = 170mΩ
RDS (max)@(VGS =-2.5V) = 125mΩ
RDS (max)@(VGS =-4.5V) = 95mΩ
CISS (typ) = 290 pF

VDSS = -20V
VGSS = ±12V
ID = 4A
RDS(max)@(VGS=-1.8V) = 157mΩ
RDS(max)@(VGS=-2.5V) = 76mΩ
RDS(max)@(VGS=-4.5V) = 56mΩ
CISS(typ) = 480 pF


The Toshiba SSM6P47NU and SSM6P49NU dual Pch MOSFETs are available now.
