Solid State Relay
OCMOS FET
PS7141C-2A,PS7141CL-2A
8-PIN DIP, 200 mA TYP. CURRENT LIMIT TYPE
2-ch Optical Coupled MOS FET
DESCRIPTION
The PS7141C-2A and PS7141CL-2A are solid state relays containing GaAs LEDs on the light emitting side (input
side) and MOS FETs including current control circuit on the output side. Current control circuit of OCMOS FET
protects this device from thermal breakdown and output circuit.
They are suitable for analog signal control because of their low offset and high linearity.
The PS7141CL-2A has a surface mount type lead.
FEATURES
• Limit current (I
LMT
= 170 to 250 mA)
• 2 channel type (1 a + 1 a output)
• Low LED operating current (I
F
= 2 mA)
• Designed for AC/DC switching line changer
• Small package (8-pin DIP)
• Low offset voltage
• PS7141CL-2A: Surface mount type
APPLICATIONS
• Exchange equipment
• Measurement equipment
• FA/OA equipment
