DATA SHEET

Solid State Relay

PS7221-2A

8-PIN SOP 200 V BREAK DOWN VOLTAGE

2-ch Optical Coupled MOS FET

DESCRIPTION

The PS7221-2A is solid state relay containing GaAs LEDs on the light emitting side (input side) and MOS FETs on

the output side.

It is suitable for analog signal control because of their low offset and high linearity.

FEATURES

• 2 channel type (1 a + 1 a output)

• Low LED operating current (IF = 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: PS7221-2A-F3, F4

• UL approved: File No. E72422 (S)

• BSI approved: No. 8241/8242

• CSA approved: No. CA 101391

OCMOS FET

APPLICATIONS

• Exchange equipment

• Measurement equipment

• FA/OA equipment
