The TLP290(V4GBTP,SE from Toshiba is a single-channel, AC-input, transistor-output optocoupler (photocoupler) designed for high-density surface-mount applications. Its input stage consists of two gallium-arsenide infrared emitting diodes connected in inverse-parallel, optically coupled to a silicon phototransistor, allowing the device to respond to either polarity of input current. Housed in a compact 4-pin SO (SOIC-4, 4.55 mm width) package, it delivers 3750 Vrms isolation between input and output while occupying minimal board space.
This variant carries the “GB” current-transfer-ratio rank (100% to 400% CTR at IF = 5 mA), the “V4” VDE-approved isolation option (EN 60747-5-2), and the “TP” tape-and-reel packaging designation for automated assembly. It is well suited to signal isolation in programmable controllers, AC/DC input modules, and power-conversion designs.
The TLP290(V4GBTP,SE can be difficult to obtain through authorized channels with limited stock and long lead times. Pacific Component Xchange is an independent distributor specializing in hard-to-find optocouplers and isolation components. We help engineers and buyers secure the parts they need, including scarce, allocated, and end-of-life optocouplers, with rigorous authenticity verification and global shipping.

It is a Toshiba single-channel, AC-input, transistor-output optocoupler (photocoupler) in a 4-SO surface-mount package, rated for 3750 Vrms isolation between input and output.
GB is the current-transfer-ratio rank (100% to 400% CTR at IF = 5 mA), V4 is Toshiba's VDE-approved isolation option (EN 60747-5-2), and TP indicates tape-and-reel packaging for automated assembly.
Per the Toshiba datasheet, the GB rank provides a current transfer ratio of 100% (min) to 400% (max) measured at a forward current of 5 mA and VCE = 5 V.
It is supplied in a compact 4-pin SO (SOIC-4, 4.55 mm width) surface-mount package, in tape-and-reel form for automated assembly.
The TLP290 offers 3750 Vrms input-to-output isolation and an 80 V (min) collector-emitter breakdown voltage, with a maximum RMS forward current of 50 mA.
Yes, it is listed as Active by Toshiba and authorized distributors. However, stock can be scarce, so Pacific Component Xchange offers it on an RFQ basis to secure availability and lead time.
