Product Description
Vishay LH1546ADF is a single channel solid state relay configured as a 4-pin Surface Mount Device (SMD) optocoupler. It features a gallium aluminum arsenide (GaAlAs) LED for input actuation and MOSFET switches at the output to provide a reliable, fast, and low-noise switching solution. This solid state relay replaces electromechanical relays in various applications requiring electrical isolation and long service life.
The device offers a maximum forward LED voltage of 1.45 V with a maximum input current of 50 mA. It has a high isolation test voltage of 5300 VRMS that provides safety and prevents electrical leakage between input and output circuits. The typical rise and fall times are 0.13 ms and 0.05 ms respectively, enabling fast switching performance in telecommunications, metering, and security equipment.
This optocoupler operates efficiently in a temperature range from -40°C up to 85°C, suitable for industrial and commercial environments. The compact 4-pin SMD package facilitates automated PCB assembly and space-saving designs. The component complies with UL1577 standards ensuring reliability and safety.
Single channel SPST normally open solid state relay reduces mechanical wear. GaAlAs LED and MOSFET combination allow low switching noise and high switching speed. High isolation voltage of 5300 VRMS provides robust electrical isolation.
