Vishay LH1540A Series Solid State Relay, 0.25 A Load Current, 350 V Load Voltage, PCB Mount, 1.5V Control

Vishay LH1540AABTR is a high-quality solid state relay designed for PCB mounting in industrial and electronic control systems. It supports a maximum load current of 0.25 A and a maximum load voltage of 350 V, enabling switching in a variety of AC and DC circuits with excellent reliability. Featuring a single-pole single-throw normally open contact configuration and MOSFET output, this relay provides low leakage current of 1μA in the off state, making it suitable for signal-level applications.

The component comes in a compact DIP-6 package with surface mount terminals, measuring 8.7 mm in length, 6.5 mm in width, and 3.8 mm in height, thus saving valuable PCB space. It operates effectively in harsh temperature conditions ranging from -40°C to 85°C, ensuring stable performance in industrial, automation, and instrumentation environments.

With a capacitance of 0.8 pF, the relay minimizes signal distortion. It is fully compliant with recognized international standards including BSI, UL 1577, FIMKO RoHS, CSA, and DIN EN 60747-5-5, assuring quality and safety in demanding applications.

Applications span industrial automation, control systems, instrumentation, and electronic switching tasks where space-saving, low power consumption, and high reliability are critical. It is especially suited for use in precise electronic control circuits requiring silent, fast switches without mechanical wear.
