OCMOS FET
PS7122-1A,-2A,PS7122L-1A,-2A
6, 8-PIN DIP, 200 V BREAK DOWN VOLTAGE
1-ch, 2-ch Optical Coupled MOS FET
DESCRIPTION
The PS7122-1A, -2A and PS7122L-1A, -2A are solid state relays containing GaAs LEDs on the light emitting side
(input side) and MOS FETs on the output side.
They are suitable for analog signal control because of their low offset and high linearity.
The PS7122L-1A, -2A have a surface mount type lead.
FEATURES
• 1 channel type (1 a output) or 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 (6, 8-pin DIP)
• Low offset voltage
• PS7122L-1A, -2A: Surface mount type
• UL approved: File No. E72422 (S)
• BSI approved: No. 8245/8246
• CSA approved: No. CA 101391
APPLICATIONS
• Exchange equipment
• Measurement equipment
• FA/OA equipment
