Solid State Relay
4-PIN ULTRA SMALL FLAT-LEAD,
LOW C × R (3.4 pF • Ω)
1-ch Optical Coupled MOS FET
The PS7801M-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 C × R (3.4 pF • Ω), low output capacitance, and low off-
state leakage current.
• Ultra small flat-lead package (4.2 (L) × 2.5 (W) × 1.85 (H) mm)
• Low C × R (C × R = 3.4 pF • Ω)
• Low output capacitance (Cout = 0.95 pF TYP.)
• 1 channel type (1 a output)
• Designed for AC/DC switching line changer
• Low offset voltage
• Ordering number of taping product: PS7801M-1A-F3: 3 500 pcs/reel
• Pb-Free product
