PRELIMINARY DATA SHEET
NEC's 4-PIN ULTRA SMALL FLAT-LEAD PS7801C-1A SUPER LOW OUTPUT CAPACITANCE 1-ch OPTICAL COUPLED MOS FET
FEATURES
* * * ULTRA SMALL FLAT-LEAD PACKAGE: 4.2 (L) x 2.5 (W) x 1.85 (H) mm SUPER LOW OUTPUT CAPACITANCE: Cout = 0.5 pF TYP. LOW C x R: C x R = 6.5 pF *
DESCRIPTION
NEC's PS7801C-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 x R, super low output capacitance, and low off-state leakage current.
