TLP108(F)

Logic Output Optoisolators Overview

The TLP108(F) is a logic output optocoupler manufactured by Toshiba Semiconductor and Storage. It features a single channel with a GaAsP light emitting diode optically coupled to a high-gain, high-speed photodetector. The device utilizes a push-pull (totem pole) output structure housed in a 6-pin MFSOP package. Key electrical specifications include an isolation voltage of 3750Vrms, a maximum DC forward current of 20 mA, and a typical forward voltage of 1.7 V. It offers a data rate of 5 Mbps, rise/fall times of 175 ns/95 ns, and a common mode transient immunity of ±10 kV/µs.
