PS2915-1
HIGH CTR, AC INPUT RESPONSE TYPE
4 PIN ULTRA SMALL PACKAGE
FLAT LEAD OPTOCOUPLER
DESCRIPTION
The PS2915-1 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.

CAUTIONS REGARDING NOISE:
Be aware that when voltage is applied suddenly between the
optocoupler's input and outout or between collector-emitters at
startup, the output side may enter the on state, even if the voltage
is within the absolute maximum ratings.
