TOSHIBA Photocoupler Photorelay TLP197D PC Card Modems PBX Measurement Equipment TLP197D Unit: mm The Toshiba TLP197D consists of an infrared emitting diode optically coupled to a photo-MOSFET in a SOP package.
TLP197D is housed in a compact and thin SOP package and has characteristics of high-withstanding voltage and low ON-state resistance, which enable TLP197D to be applied in hook switches, dial-pulse switches for modems and facsimiles, and switches for test circuit switching in PBXs.
