Specifications & Application Scenarios
Specifications
The APY111G3S is a compact Photo MOS SSR (1 Form A, SPST-NO) with a 3.5A load current, 40V load voltage (AC/DC), and an ultra-low 0.05Ω on-state resistance, minimizing power loss. It provides 2500Vrms isolation, operates from -40°C to 85°C, and is controlled by 1.2–1.5VDC. Switching times are 400μs (on) and 30μs (off). Housed in an SOP-4 surface-mount package with tape-and-reel packaging, it suits automated assembly.
Application Scenarios
This relay is designed for high-efficiency, isolated switching in space-constrained applications. It is ideal for:
-
Industrial Automation: PLC I/O modules, sensor interfaces, and small actuator control, where noise immunity and reliability are critical.
-
Consumer & IoT Electronics: Smart home devices, power management circuits, and battery-powered systems, benefiting from its low on-resistance and compact SOP-4 footprint.
-
Medical & Communication Equipment: Patient monitors, diagnostic tools, and network hardware, leveraging its fast switching and robust isolation for safety and performance.
Its combination of high current capability, low loss, and industrial temperature range makes it a versatile solution for modern, high-density designs requiring reliable, silent switching.
