Specifications: The APV214EH is the SMD-6 version of a high-isolation, medium-voltage PhotoMOS SSR. Rated for 120mA at 400V (AC/DC), it has a 16Ω on-state resistance and 5000Vrms isolation. Switching times are 230μs (on) and 50μs (off). It operates from -40°C to 85°C with 1.2-1.4VDC control. Application Scenarios: Provides a surface-mount solution for safe medium-voltage switching with maximum isolation. Ideal for miniaturized medical devices, high-density power supply boards, and industrial control modules that must safely interface with 400V circuits in a noisy environment.
