4-PIN ULTRA SMALL FLAT-LEAD, LOW OUTPUT CAPACITANCE (1.6 pF),
1-ch Optical Coupled MOS FET
−NEPOC
Series−
DESCRIPTION
The PS7801K-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.
An ultra small flat-lead package has been provided which realizes a reduction in mounting area of about 50%
compared with the PS72xx series.
It is suitable for high-frequency signal control, due to its low off-state leakage current and low output capacitance.
FEATURES
• Ultra small flat-lead package (4.2 (L)
