NEC PS7241E-1A Solid State Relay Datasheet
The PS7241E-1A is an optically coupled solid‑state relay that combines a GaAs infrared LED on the input side with a normally‑open MOSFET on the output side. It is supplied in a compact 4‑pin SOP package (height 2.1 mm) and is suited for battery‑driven mobile devices, laptops, PDAs, modem cards, telephones, fax machines, and measurement equipment.
Key electrical characteristics include a 400 V breakdown voltage, 120 mA continuous load current, 1 A peak forward current, 1500 V isolation voltage, and a power dissipation of 50 mW (300 mW in AC/DC switching mode). The device meets UL (No. E72422) and BSI (No. 8241/8242) safety standards.
