DESCRIPTION

The PS7205B-1A is a low on-state resistance solid state relay containing a GaAs LED on the input side and MOS

FETs on the output side.

It is suitable for PLC, etc. because of its large continuous load current and low on-state resistance.

FEATURES

• Low on-state resistance (Ron = 0.9 Ω TYP.)

• Large continuous load current (I

• High-speed switching time (t

• 1 channel type (1 a output)

• Designed for AC/DC switching line changer

• Small and thin package (4-pin SOP, Height = 2.1 mm)

• High isolation voltage (BV = 1 500 Vr.m.s.)

• Low offset voltage

• Ordering number of taping product : PS7205B-1A-E3, E4: 900 pcs/reel

: PS7205B-1A-F3, F4: 3 500 pcs/reel

• Pb-Free product

APPLICATIONS

• Measurement equipment

• FA equipment
