The TLP3906(E) is an optocoupler from Toshiba comprised of a GaAAs infrared LED and a photo diode. It is a small form-factor part packaged in the outline of a 4-pin DIP to enable high mounting density in electronic circuits. The TLP3906(E) is designed to provide an electrical isolation between two circuits while transferring signals with minimal signal distortion. Its photo diode output optocoupler design along with high transfer rate, wide operating temperature range, and low power consumption makes it reliable for power supply and data communication isolation applications. Moreover, it also provides a consistent optical performance over the entire product lifetime making it suitable for environments with varying environmental conditions.
