Product details

The Toshiba TLP2355(TPL,E is a single-channel photocoupler in a 6-SO, 5-lead package, delivering 3750Vrms galvanic isolation between a DC input and a push-pull, totem-pole output. It is designed for industrial and automotive environments where you need to pass a logic-level signal across a safety barrier — think motor-drive feedback, PLC digital inputs, or isolated serial links.

25 kV/µs CMTI — keeps the output clean when the motor drive switches

At 25kV/µs, this part handles the edge rates you see in IGBT and SiC switching without false toggles.

250 ns propagation delay — timing budget for the signal path

Propagation delay is 250ns max. Rise and fall times are 15ns and 12ns typical.

Supply range and temperature — fits industrial rails and hot cabinets

Supply voltage spans 3V to 20V, so it works on 3.3V logic rails, 5V PLC buses, and 12V or 15V industrial supplies without a secondary regulator.
