Solid State Relay
OCMOS FET
PS7241-2B
8-PIN SOP, 400 V BREAK DOWN VOLTAGE NORMALLY CLOSE TYPE
2-ch Optical Coupled MOS FET
DESCRIPTION
The PS7241-2B is a solid state relay containing GaAs LEDs on the light emitting side (input side) and normally
close (N.C.) contact MOS FETs on the output side.
It is suitable for analog signal control because of their low offset and high linearity.
FEATURES
• 2 channel type (1 b + 1 b output)
• Low LED operating current (I
F
= 2 mA)
• Designed for AC/DC switching line changer
• Small and thin package (8-pin SOP, Height = 2.1 mm)
• Low offset voltage
• Ordering number of taping product: PS7241-2B-F3, F4
• UL approved: File No. E72422 (S)
• BSI approved: No. 8241/8242
• CSA approved: No. CA 101391
APPLICATIONS
• Exchange equipment
• Measurement equipment
• FA/OA equipment
