4-PIN SOP 400 V BREAK DOWN VOLTAGE
1-ch Optical Coupled MOS FET
Solid State Relay
OCMOS FET
PS7241-1A
DESCRIPTION
The PS7241-1A is a solid state relay containing GaAs LEDs on the light emitting side (input side) and normally
open (N.O.) contact MOS FETs on the output side.
It is suitable for analog signal control because of its low offset and high linearity.
FEATURES
Small and thin package (4-pin SOP, Height = 2.1 mm)
1 channel type (1 a output)
Low LED operating current (I
F
= 2 mA)
Designed for AC/DC switching line changer
Low offset voltage
