Celduc SKD10306 DC Solid-State Relay

Celduc SKD10306 DC solid-state relay is a compact photorelay that switches DC loads with a rated 3 A current and a maximum 60 VDC load, housed in a 4‑SIP package designed for straightforward PCB mounting. The input control range is 3–30 VDC, enabling direct interfacing with standard logic signals, while the output is a DC, optically isolated switch (photocoupled) that provides electrical isolation between the control circuitry and the DC load and is listed as SPST‑NO (1 Form A) in a 4‑SIP package. The device supports a load voltage range of 2–60 VDC, a peak load voltage of 60 V, and a continuous load current rating of 3 A, with operation from -40 °C to 80 °C, which makes it suitable for both industrial and embedded environments. In board-level DC switching tasks in automation and instrumentation environments, the SKD10306 offers a solid-state alternative to mechanical relays, delivering silent operation and long life thanks to its photo‑coupled design and absence of moving parts. The 4‑SIP packaging and PCB‑mounting compatibility help keep designs compact and standard across Celduc’s SKD DC‑SSR family.
