NEC's 4-PIN ULTRA SMALL FLAT-LEAD,
LOW OUTPUT CAPACITANCE
PS7801-1A
1-CH OPTICAL COUPLED MOSFET
FEATURES
• LOW C x R :
C x R = 12.6 pF •
Ω
• LOW OUTPUT CAPACITANCE
C
OUT
= 1.2 pF
• 1 CHANNEL TYPE:
1a output
• DESIGNED FOR AC/DC SWITCHING LINE CHANGER
• ULTRA SMALL FLAT-LEAD PACKAGE:
4.2 (L) X 2.5 (W) X 1.85 (H) mm
• LOW OFFSET VOLTAGE
• ORDERING NUMBER OF TAPING PRODUCT:
PS7801-1A-F3, F4 (3 500 pcs/reel)
It is suitable for high frequency signal control, due to its low
C x R, low on-state resistance, and low off-state leakage
current.
DESCRIPTION
NEC's PS7801-1A is a low output capacitance solid state
relay containing GaAs LEDs on the light emitting side (input
side) and MOSFETs on the output side.
An ultra small
ß
at-lead package has been provided which
realizes a reduction in mounting area about 50% compared
with the PS72xx series.
