TLP785(D4-GR,F) – Optocoupler – Toshiba

The Toshiba TLP785(D4-GR,F) is a single-channel transistor-output optocoupler in a DIP4 package with 5000 Vrms isolation and a GR-rank current transfer ratio (CTR) of 100%-300%. Available for RFQ at Pacific Component Xchange.

The Toshiba TLP785(D4-GR,F) is a single-channel, transistor-output optocoupler (photocoupler) consisting of an infrared light-emitting diode optically coupled to a silicon phototransistor in a 4-lead plastic DIP (DIP4) package with a 7.62 mm lead pitch. The D4 designation indicates the VDE-approved (EN 60747-5-5) safety-standard option, the GR suffix specifies the current transfer ratio (CTR) rank of 100%-300%, and the trailing F denotes the RoHS-compatible product designation. It delivers a guaranteed isolation voltage of 5000 Vrms (AC, 60 s, minimum), making it well suited for AC/DC line isolation, feedback, and signal-coupling applications across consumer, industrial, and power-supply designs.
