Solid State Relay
OCMOS FET
PS7241-AT1, PS7241-AT5
PHOTO TRANSISTOR AND MOS FET OUTPUT TYPE
8-PIN SOP 400 V BREAK DOWN VOLTAGE
2-ch Optical Coupled MOS FET
DESCRIPTION
The PS7241-AT1 and PS7241-AT5 are solid state relays containing GaAs LEDs on the light emitting side (input
side) and MOS FETs (+ Photo transistor) on the output side.
They are suitable for analog signal control because of their low offset and high linearity.
FEATURES
• 2 channel type (OCMOS FET + Photocoupler)
• 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-AT1-F3, F4, PS7241-AT5-F3, F4
• Safety standards
• UL approved: File No. E72422 (S)
• BSI approved: No. 8190/8191
• CSA approved: No. CA 101391
APPLICATIONS
• Exchange equipment
• Measurement equipment
