DATA SHEET

Solid State Relay

PS7221A-2A

8-PIN SOP, 260 V BREAK DOWN VOLTAGE

2-ch Optical Coupled MOS FET

DESCRIPTION

The PS7221A-2A is a 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 its low offset and high linearity.

FEATURES

• 2 channel type (1 a + 1 a output)

• Low LED operating current (IF = 1 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: PS7221A-2A-F3, F4

OCMOS FET

APPLICATIONS

• Exchange equipment (FAX, MODEM, OCU + SLIC, etc.)

• Measurement equipment

• FA/OA equipment
