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.
Pacific Component Xchange is an independent distributor specializing in hard-to-find and allocated power-management ICs and optocouplers. The TLP785(D4-GR,F) GR-rank, VDE-option variant frequently sees limited authorized-distributor stock, and exact CTR-rank and option combinations can be difficult to secure. Our team sources verified, authentic Toshiba product, supports obsolete and end-of-life procurement, and ships globally with rigorous authenticity and quality screening. Request a quote (RFQ) today and our sourcing specialists will confirm availability, lead time, date codes, and pricing for your required quantity.
The clean, verified orderable code is TLP785(D4-GR,F). The TLP785 is the base device, D4 is the VDE-approved option, GR is the CTR rank, and the trailing F denotes the RoHS-compatible designation.
GR is the current transfer ratio (CTR) rank. For the TLP785, the GR rank specifies a CTR of 100% to 300% (measured at IF = 5 mA, VCE = 5 V). The device family overall spans a 50% to 600% CTR range across all ranks.
The TLP785 provides a minimum isolation voltage of 5000 Vrms (AC, 60 seconds), per the Toshiba datasheet.
The D4 option indicates the VDE-approved type qualified to the EN 60747-5-5 safety standard for optical isolators, which is required in many AC-line-isolation and power-supply applications. Toshiba notes that when a VDE-approved type is needed, the Option(D4) should be designated.
It is supplied in a 4-pin plastic dual-in-line package (DIP4) with a 7.62 mm lead pitch, a through-hole mounting format. (The TLP785F variant uses a 10.16 mm pitch lead-formed body.)
Key absolute maximum ratings are a collector-emitter voltage (VCEO) of 80 V, a collector current (IC) of 50 mA, and an LED forward current (IF) of 60 mA, per the Toshiba datasheet.
