MOS FET Relays SOP 4-pin, General-purpose Type
General-purpose MOS FET Relays 
in SOP 4-pin packages 
for a wide range of applications
• Load voltage: 80 V
■Application Examples
■Ordering Information
* The AC peak and DC value are given for the load voltage and continuous load current.
Note: To order tape packaging for Relays with surface-mounting terminals, add “(TR)” to the end of the model number.
■Absolute Maximum Ratings (Ta = 25°C)
* The dielectric strength between the input and output was checked by applying voltage between all pins as a group on the LED side 
and all pins as a group on the light-receiving side.
RoHS Compliant 
Note: The actual product is marked differently from the 
image shown here.
