PS2702

The PS2702 is optically coupled isolators consisting of a GaAs light emitting diode and an NPN silicon darlington-con nected phototransistor.Each is mounted in a plastic SOP (Small Out-line Package) for high density applications.This package has shield effect to cut off ambient light.

Features of the PS2702 are:(1)high current transfer ratio (CTR = 2 000 % TYP.);(2)high isolation voltage (BV = 3 750 Vr.m.s.);(3)small and thin (SOP) package;(4)high-speed switching (tr, tf = 200 ms TYP.);(5)ordering number of taping product (1-ch only): PS2702-1-E3, E4, F3, F4;(6)UL approved: file No. E72422;(7)VDE0884 approved (Option).
