LTV-217-TP1-B-G
Category
The Lite-On LTV-217-TP1-B-G provides robust optoisolation with 3.75kV isolation, 80V load capability, and industrial temperature range (-55°C to +110°C). Ideal for noise-prone control systems and medical devices, it features 30mA output, 1.2V forward voltage, and 50-600% CTR. Designers should prioritize proper layout with 3mm isolation gaps, thermal management at 50°C/W, and verify compatibility with logic levels. Best suited for applications requiring stable isolation in harsh environments with voltage up to 80V.
