TLP785F(D4-GR,F) – Optocoupler – Toshiba

About this part

The Toshiba TLP785F(D4-GR,F) is a single-channel transistor-output photocoupler (optocoupler) consisting of an infrared emitting diode (IRED) optically coupled to a silicon phototransistor. The “F” suffix designates the lead-formed variant of the TLP785, in which the leads are shaped for a longer creepage distance and long-pitch (10.16 mm) surface mounting. The “GR” code specifies the current transfer ratio (CTR) rank, and the trailing “D4…,F” elements are Toshiba option (VDE) and tape/packing designators.

Key Features

• Single-channel (1-channel) transistor-output photocoupler
• Current transfer ratio (CTR) rank GR: 100% to 300% (IF = 5 mA, VCE = 5 V, Ta = 25°C)
• Isolation voltage: 5000 Vrms (minimum, AC, 60 s)
• Collector-emitter voltage: 80 V (minimum)
• DC input, phototransistor output
• Lead-formed DIP4 package (10.16 mm pitch) for long creepage distance and surface mounting
• UL 1577 recognized, cUL recognized, VDE-approved (Option D4), CQC and SEMKO approved
• RoHS-compatible

Applications

• Switching power supplies and AC main voltage detection
• Communication and signal-transmission interfaces between different voltage circuits
• Solid-state relays
• Office equipment and home electric appliances
• Contactless controller outputs and industrial controllers
