LH1540AAB Description

Short technical summary and product information.

The Siemens LH1540AAB is a robust 1 Form A solid-state relay designed for applications requiring reliable switching. It features a normally open (NO) SPST configuration, making it suitable for replacing electromechanical relays in various systems.

 

Key electrical specifications include a maximum load voltage of 350V and a maximum load current of 120mA. The relay provides a high isolation test voltage of 5300Vrms, ensuring safety and reliability. Its typical on-resistance is 20Ω, with a maximum of 25Ω. The device operates with a maximum input voltage of 1.45V and a forward current of 50mA.

 

This solid-state relay is constructed using a GaAIAs LED for actuation and a monolithic die for the switch output, fabricated in a high-voltage dielectrically isolated technology. It includes current-limiting circuitry for protection against voltage surges.

 

The LH1540AAB is available in an SMD-6 package, suitable for surface mounting on PCBs. It is also available on tape and reel for automated assembly processes. The operating temperature range is from -40°C to 85°C.
