4-PIN SMALL FLAT-LEAD, LOW ON-STATE RESISTANCE
1-ch Optical Coupled MOS FET
DESCRIPTION
The PS7904-1A 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 = 29.7 pF • )
Low on-state resistance (R
on
= 1.1 TYP.)
Large continuous load current (I
L
= 400 mA)
1 channel type (1 a output)
Designed for AC/DC switching line changer
Low offset voltage
