Flat Optocouplers/Isolators Offer CTR Selection From 50% To 600%

The high-density Mini Flat Packs integrate phototransistor optocouplers and isolators for interfacing signal transmissions between systems of different potentials and impedances. The devices are drop-in replacements for Toshiba TLP181 and 121, NEC PS2701 and Sharp PC357 parts. The IS121, IS181, IS357 and IS2701-1 Mini Flat Packs are available on tape-and-reel and consist of an infrared light emitting diode and NPN silicon photo transistor in a space-efficient package. Electrical features include various CTR selections from 50% to 600% and a 3.75 kV_RMS, 5.3 kV peak isolation voltage capability.
