PS7241E-1A

4-PIN SOP 400 V BREAK DOWN VOLTAGE

1-ch Optical Coupled MOS FET

DESCRIPTION

The PS7241E-1A is an optically coupled element that combines a GaAs infrared LED on the input side with a

normally-open MOS FET on the output side to realize an excellent cost performance.

The small, thin package and high sensitivity of this element makes it ideal for battery-driven mobile devices, and its

small offset voltage at power-on and good linearity are also make it suitable for controlling micro analog signals.

FEATURES

• Small and thin package (4-pin SOP, Height = 2.1 mm)

• 1 channel type (1 a output)

• Designed for AC/DC switching line changer

• Low offset voltage

• Ordering number of taping product: PS7241E-1A-E3, E4, F3, F4

• UL awaiting approval

• BSI awaiting approval

APPLICATIONS

• Laptop PC, PDA

• Modem card

• Telephone, FAX

• Measurement equipment
