TOSHIBA TLP197G is a small outline photo relay from TOSHIBA, suitable for surface mount assembly. The TLP197G consists of a gallium arsenide infrared emitting diode optically coupled to a photo-MOS FET in a six lead 2.1mm height package, which enable TLP197G to be applied in card modems. The TLP197G is a bi-directional switch which can replace mechanical relays in fax machines and modems etc.
The TLP197G is a miniature flat photo‑relay that combines a GaAs infrared LED with a photo‑MOS FET in a 6‑lead, 2.1 mm height SOP package. It is intended for surface‑mount applications such as fax machines, modems, and other equipment where a bi‑directional switch can replace mechanical relays.
