FLAT-LEAD PHOTOCOUPLER
DESCRIPTION
The PS2911-1 is an optically coupled isolator containing a GaAs light emitting diode and an NPN silicon
phototransistor in one package for high density mounting applications.
An ultra small flat-lead package has been provided which realizes a reduction in mounting area of about 30% compared
with the PS28xx series.
FEATURES
Ultra small flat-lead package (4.6 (L) 2.5 (W) 2.1 (H) mm)
PIN CONNECTION
High current transfer ratio (CTR = 200% TYP. @ I = 1 mA, V = 5 V)
F CE
(Top View)
High isolation voltage (BV = 2 500 Vr.m.s.)
