Littelfuse TSDB431 is a reliable and high-quality solid-state relay with a maximum load rating of 1 A steady state and 10 A inrush at 60°C. It features 0.25 in. (6.35 mm) male quick connect terminals for easy installation. With an input tolerance of ±15%, it operates at frequencies of 50/60 Hz. The relay has a humidity tolerance of 95% relative non-condensing and a repeat accuracy of ±0.5% or 20 ms. It provides insulation resistance of ≥100 and offers a setpoint vs ambient temperature and operating voltage tolerance of ≤±2%. The device is encapsulated and consumes less than 1 W of power. It has a time delay tolerance of ±1% and a reset time of ≤150 ms. The relay ensures safety with dielectric breakdown of ≥2000V from terminals to the mounting surface. It has an output voltage drop of ≅2.5 V at 1 A and an open state leakage current of ≅5 A at 230 V ac. The initiate time is ≤20 ms.
