The PS7206-1A is a low on-state resistance solid state relay with large continuous load current and low on-state resistance, suitable for PLC applications.
The PS7206-1A is a low‑on‑state‑resistance solid‑state relay that uses a GaAs LED on the input side and a MOSFET on the output side. It is designed for AC/DC switching applications such as PLCs, offering a compact 4‑pin SOP package (2.1 mm height).
Key specifications include a typical on‑state resistance of 0.6 Ω, continuous load current of 600 mA, isolation voltage of 1500 V rms, and operation over –40 °C to +85 °C. The device complies with UL (File No. E72422) and BSI (No. 8241/8242) safety standards and is supplied in various tape and reel formats.
