The Toshiba TLP109 mini-flat coupler is a small-outline coupler suitable for surface-mount assembly. The TLP109 consists of a high-output-power GaAℓAs light emitting diode optically coupled to a high-speed photodiode-transistor chip. The TLP109 is housed in the 6-pin SO package and guarantees acreepage distance of ≥5.0 mm, a clearance of ≥5.0 mm and an insulation thickness of ≥0.4 mm. Therefore, the TLP109 meets the reinforced insulation class requirements of international safety standards.
