The Toshiba TLP series are 12‑pin DIP solid‑state relays available in 3‑channel configurations. Each device integrates four‑pin DIP photocouplers in a single plastic package and is designed for three‑phase motor control and data interface applications.
The series includes a range of output types—AC input, transistor, Darlington, Triac, and low‑input‑current options—each with isolation voltages of 2500 V or 5000 V AC. Detailed pin configurations and electrical parameters are provided for each model, along with UL and JEDEC safety certifications.
