The TOSHIBA mini flat coupler TLP137 is a small outline coupler, suitable for surface mount assembly.
TLP137 consists of a gallium arsenide infrared emitting diode, optically coupled to a photo transistor, and provides high CTR at low input current.
TLP137 base terminal is for the improvement of speed, reduction of dark current, and enable operation.
