)/TLP785
TLP785 is a 4-pin ultra-small optocoupler made by Toshiba. It contains a GaAlAs LED driving an integrated PhotoMOS FET. The device is housed in a DIL4/SOP4 type package and is ideal for space-constrained designs. The TLP785 offers high isolation voltage (4,250V), fast response (1.3ns), high isolation resistance (1012 ? at 500VDC) and low input current (2mA). It is used for signal transmission applications and helps protect susceptible circuitry from transient power spikes or surges.
