What are the key features of LH1540AT?
- 5300 V isolation voltage providing outstanding galvanic separation for safety-critical circuits
- Low control voltage of 1.15 V and 1 mA control current for logic-level drive compatibility
- UL-approved high-reliability rating in a DIP package for industrial and medical equipment
What is LH1540AT used for?
The LH1540AT solid-state relay is ideal for medical equipment, industrial isolation barriers, and safety-critical signal switching where 5300 V galvanic isolation between control and load circuits is required. Its low 1.15 V control voltage allows direct drive from 3.3 V or 5 V logic without additional buffers. The DIP package facilitates easy through-hole PCB assembly in low-to-medium volume production.

Frequently Asked Questions
What isolation voltage does the LH1540AT provide and why does it matter for medical designs?
The LH1540AT provides 5300 V isolation voltage between the control and load sides, which is essential for medical equipment designs that must meet IEC 60601 patient isolation requirements to prevent electric shock hazards.
What control voltage and current are needed to activate the LH1540AT relay?
The LH1540AT requires a control voltage of 1.15 V and a control current of 1 mA (0.001 A), making it directly compatible with 3.3 V and 5 V digital logic outputs without requiring additional driver stages.
Is the LH1540AT suitable for replacing an electromechanical relay in a high-isolation industrial application?
Yes, the LH1540AT is a solid-state alternative offering 5300 V isolation, high-reliability UL approval, and a DIP package. Unlike electromechanical relays, it has no moving parts, supports DC input, and offers longer operational life in industrial switching applications.
