The PS7141E-1A and PS7141EL-1A are solid state relays with GaAs LEDs on the input side and MOS FETs on the output side. They are suitable for analog signal control due to their low offset and high linearity. The PS7141EL-1A has a surface mount lead design.
The NEC PS7141E-1A and PS7141EL-1A are solid‑state relays that combine a GaAs LED input with a MOSFET output. They are designed for AC/DC switching applications, offering a small 6‑pin DIP package and low offset voltage for precise analog signal control.
The document provides absolute maximum ratings, recommended operating conditions, electrical characteristics, and safety approvals (UL, BSI, SEMKO, DEMKO, NEMKO, FIMKO). It also includes ordering information, package dimensions, and handling instructions for the GaAs material used in the device.
