TLP3051F(S),TLP3052F(S) are photocouplers produced by Toshiba. They are mainly used in office machines, household appliances, triac drivers, solid state relays and other fields.
The Toshiba TLP3051F(S) and TLP3052F(S) are photo‑triac devices optically coupled to a gallium‑arsenide infrared emitting diode in a six‑lead plastic DIP package. The document lists electrical parameters such as peak off‑state voltage, trigger LED current and on‑state current, as well as mechanical ratings like creepage distance and clearance.
The devices are UL, VDE, BSI, SEMKO and other approved, and include safety and usage restrictions. Users are advised to follow Toshiba’s handling guide and avoid use in high‑risk applications such as medical or aerospace equipment.
