PS2911-1

HIGH CTR, 4-PIN ULTRA SMALL PACKAGE

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)

• High current transfer ratio (CTR = 200% TYP. @ I

• High isolation voltage (BV = 2 500 Vr.m.s.)

• Ordering number of taping product: PS2911-1-F3, F4: 3 500 pcs/reel

• Safety standards

• UL approved: File No. E72422

• BSI approved: No. 8657, 8658

• DIN EN60747-5-2 (VDE0884 Part2) approved (Option)

APPLICATIONS

• DC/DC converter

• Modem/PC card

F = 1 mA, VCE = 5 V)
