Vishay Intertechnology, Inc. Solid State Relays LH1525AAB

The Vishay solid-state relay (SSR) with part number 21H0696 is designed for applications requiring a load voltage of up to 400V and a continuous load current of 125mA. It features a single-pole, single-throw (SPST) normally open configuration, making it suitable for both AC and DC load types. The relay operates with a low input current, which is advantageous for battery-powered and energy-sensitive applications. This device is constructed using a GaAIAs LED for actuation and an integrated monolithic die that includes a photodiode array and MOSFET switches. It provides high-speed operation with a turn-on time of approximately 0.22 ms and a turn-off time of around 0.6 ms. The relay also offers a high isolation voltage of 5300 V_RMS, ensuring safety in various applications. The SSR is compliant with multiple safety standards, including UL1577 and BSI certifications, and is suitable for use in industrial controls, programmable controllers, and instrumentation. Its surface mount design allows for easy integration into compact electronic systems. The device operates effectively across a temperature range of -40¬8C to +85¬8C, making it versatile for different environmental conditions.
