描述

The LCA120L is a Photomos solid state relay with 1-Form A output configuration designed for AC and DC switching applications. It features a maximum switching voltage of 250V peak, with AC mode switching current of 120mA and DC mode switching current of 200mA, providing reliable performance across diverse load conditions. The relay operates with an LED input requiring 10–30mA recommended forward current and 1.1–1.4V forward voltage at 20mA. Key performance characteristics include a maximum on-resistance of 35O in AC mode and 8.75O in DC mode (at 5mA input, 50mA load), turn-on time of 5.0ms maximum, and turn-off time of 1.0ms maximum. The LCA120L is ideal for industrial control, instrumentation, and switching applications where isolation and fast response times are required.
