The Toshiba TLP3020, TLP3021, TLP3022 and TLP3023 series are GaAs infrared‑emitting diode (IRED) and photo‑triac optocouplers packaged in a six‑lead plastic DIP. They are intended for use in office machines, household equipment and as solid‑state relay/triac driver components. The devices combine a gallium arsenide LED with a photo‑triac, providing electrical isolation between input and output circuits.
Key specifications include an off‑state voltage of 400 V (min), on‑state current of 100 mA (max), isolation voltage of 5000 V (min) and compliance with UL1577, VDE and other safety standards. Mechanical data such as pin configuration, creepage distance, clearance and insulation thickness are provided for reliable PCB layout.
