OCMOS FET
PS7241E-1B
4-PIN SOP 400 V BREAK DOWN VOLTAGE
NORMALLY CLOSE TYPE
1-ch Optical Coupled MOS FET
−NEPOC
Series−
DESCRIPTION
The PS7241E-1B is an optically coupled element that combines a GaAs infrared LED on the input side with a
normally close 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 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 b output)
• Low LED operating current (I
F
= 3 mA)
• Designed for AC/DC switching line changer
• Low offset voltage
• Ordering number of taping product: PS7241E-1B-E3, E4, F3, F4
• Pb-Free product
<R>
• Safety standards
• UL approved: File No. E72422
• BSI approved: File No. 8241/8242
