The Toshiba TLP290(V4-GR-TPR,E) is a single-channel transistor-output photocoupler designed for AC-input applications. It pairs two GaAs infrared emitting diodes connected in inverse-parallel with a silicon phototransistor, allowing the device to be driven directly by alternating input current without an external bridge. Housed in Toshiba’s small, thin SO-4 (4-pin SOIC) package, it is well suited to high-density surface-mount designs. The V4 option designates the EN 60747-5-5 (VDE) approved reinforced-isolation variant, and the GR suffix specifies a current transfer ratio (CTR) rank of 100% to 300%.
The V4 (VDE-approved) and specific CTR-rank variants of the TLP290 frequently see limited authorized-distributor stock, making them a challenge to source on demand. Pacific Component Xchange specializes in hard-to-find and allocation-constrained power-management ICs and optocouplers. We help engineers and buyers secure the exact rank and packaging they need, verify authenticity, and ship globally. Whether you require a single reel for a prototype build or production quantities of this Toshiba isolator, submit an RFQ today and our sourcing team will respond with availability and a quote. Count on us for authenticity assurance, traceability, and reliable fulfillment of obsolete and difficult-to-locate components.
The V4 option designates the EN 60747-5-5 (VDE) approved version of the TLP290, providing certified reinforced isolation. Toshiba requires you to specify Option(V4) when an EN 60747-5-5 approved type is needed.
GR is a current transfer ratio (CTR) rank classification. For the TLP290, the GR rank specifies a CTR of 100% to 300%, measured at the rated input current.
The TLP290 provides a minimum isolation voltage of 3750 Vrms, making it suitable for high-density surface-mount designs requiring strong galvanic isolation.
It ships in Toshiba's small, thin SO-4 (4-pin SOIC) surface-mount package, supplied on tape and reel as indicated by the TPR / -E,T packaging code.
The TLP290 is an AC-input device. It uses two infrared emitting diodes connected in inverse-parallel, so it can be driven directly by AC input current (and DC of either polarity).
