PS2911-1
NEC's HIGH CTR
4 PIN ULTRA SMALL PACKAGE
FLAT LEAD OPTOCOUPLER
FEATURES
• SMALL AND THIN PACKAGE:
4.6 (L) x 2.5 (W) x 2.1 (H) mm
• HIGH CURRENT TRANSFER RATIO:
CTR = 200% TYP @ IF = 1 mA, VCE = 5 V

• TAPE AND REEL AVAILABLE
DESCRIPTION
NEC's 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.
APPLICATIONS
• DC/DC CONVERTER
• MODEM/PC CARD
