TLP2355(V4-TPL,E(T) – High-Speed Logic-Output Optocoupler – Toshiba

The Toshiba TLP2355 is a single-channel, high-speed logic-output optocoupler in a 5-pin SO6 package, featuring 3750 Vrms isolation, a 5 Mbps data rate, and a totem-pole output for digital interface and IPM signal isolation.

The Toshiba TLP2355 is a single-channel, high-speed logic-output optocoupler that pairs a GaAlAs infrared LED with a high-gain, high-speed photodetector IC. Built in a compact 5-pin SO6 surface-mount package, it delivers a totem-pole output stage with current sourcing and sinking capability, making it well suited to digital signal isolation across high-voltage boundaries. The “V4” designation denotes the safety-approved variant aligned to IEC/EN 60747-5-5 reinforced-isolation requirements.
