TLP290(V4-GR-TPR,E) – Optocoupler – Toshiba

The Toshiba TLP290 (V4-GR) is a single-channel AC-input, transistor-output photocoupler rated at 3750 Vrms isolation in a compact SO-4 surface-mount package, with the V4 option for EN 60747-5-5 (VDE) reinforced isolation approval and GR-rank CTR of 100-300%.

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%.
