PS7901D-1A

−NEPOC Series− (OCMOS FET)

4-PIN SMALL FLAT-LEAD, LOW OUTPUT CAPACITANCE (0.75 pF)

1-ch Optical Coupled MOS FET

DESCRIPTION

The PS7901D-1A is a low output capacitance solid state relay containing a GaAs LED on the light emitting side (input

side) and MOS FETs on the output side.

A small flat-lead package has been provided which realizes a reduction in mounting area of about 50% compared with

the PS78xx series.

It is suitable for high-frequency signal control, due to its low C

× R, low output capacitance, and low off-state leakage

current.

FEATURES

• Small flat-lead package (2.5 (L) × 2.3 (W) × 2.9 (H) mm)

• Low C × R (C × R = 9 pF • Ω)

• 1 channel type (1 a output)

• Designed for AC/DC switching line changer

• Low offset voltage

• Embossed tape product : PS7901D-1A-F3

: 3 500 pcs/reel

• Pb-Free product

APPLICATIONS

• Measurement equipment
