LCA110S Optomos SSR 1A 350V DC SMD 6-Pin MOSFET Relay IXYS 35 RDS

The LCA110S Optomos Solid State Relay is a compact high-reliability switching component designed for efficient DC load control in low-power industrial and electronic applications. Built with MOSFET-based output technology, it delivers fast, silent, and wear-free switching performance, making it ideal for modern automation and signal control systems.

With a load rating of 1A at 350V, the LCA110S is optimized for precise DC switching applications where compact size and high isolation are critical. Its low on-resistance (RDS of approximately 35 ) helps minimize power loss and heat generation, ensuring stable operation and improved energy efficiency in continuous-use environments.

This Optomos SSR is designed in a compact 6-pin SMD configuration, making it suitable for high-density PCB layouts and automated assembly processes. Its small footprint allows integration into space-constrained designs such as industrial controllers, measurement systems, telecommunications equipment, and embedded electronics.

The relay features optically isolated input-output separation, ensuring strong electrical protection between control signals and load circuits. This enhances system safety and protects sensitive electronics from voltage spikes and electrical noise.

Engineered for reliability, the LCA110S supports continuous operation with a load current capability suitable for low-to-medium power DC switching tasks. It is commonly used in applications requiring frequent switching cycles where mechanical relays would suffer from wear and reduced lifespan.

Its solid-state construction eliminates moving parts, ensuring silent operation, high switching speed, and long service life. This makes it especially suitable for precision control systems where stability and durability are essential.
