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) × 2.5 (W) × 1.85 (H) mm • SUPER LOW OUTPUT CAPACITANCE: Cout = 0.5 pF TYP. • LOW C × R: C × R = 6.5 pF • Ω • 1 CHANNEL TYPE: 1 a output • DESIGN FOR AC/DC SWITCHING LINE CHANGER • LOW OFFSET VOLTAGE • ORDERING NUMBER OF TAPING PRODUCT: PS7801C-1A-F3, F4: 3 500 pcs/reel 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 × R, super low output capacitance, and low off-state leakage current.
