MOS output solid-state relays (also called photorelays or MOSFET relays) use optically coupled MOSFETs to switch low-level signals and small DC loads with extremely low on-resistance and virtually unlimited mechanical life — ideal for test equipment, data acquisition systems, medical devices, and battery management systems. Our MOS output SSR inventory covers single-pole and dual-pole configurations with normally open (NO) and normally closed (NC) contacts from Panasonic (AQV/AQY series), Omron (G3VM series), Toshiba (TLP series), and IXYS/CPC — with load voltages from 20V to 600V, load currents from 10mA to 5A, and on-resistance from 0.02Ω to 10Ω.
Low-resistance (< 0.1ω) MOS output relays for battery switching and high-voltage (>400V) photorelays for industrial automation are frequently used. Welllinkchips stocks a range of MOS output SSR configurations and can source obsolete or hard-to-find photorelay types for legacy test equipment and medical device repair.
