Specifications: The APW221EH is the SMD-8 version of a dual-channel PhotoMOS SSR. Each of its 2 Form A (SPST-NO) channels handles 250mA at 60V AC/DC, with a 3.5惟 on-state resistance. It provides 5000Vrms isolation and switches in 100渭s/350渭s. Operating from -40掳C to 85掳C, it uses a 1.1-1.5VDC control signal. Application Scenarios: Designed for the same dual-channel switching needs as APW221E but in a surface-mount form factor. Ideal for space-constrained applications in consumer electronics, communication devices, compact industrial controllers, and automated test equipment where two isolated signal or power paths need to be controlled reliably on a high-density PCB.
