Specifications: The APW414E is a dual-channel, high-voltage Normally Closed (SPST-NC) PhotoMOS SSR in DIP-8. Each channel handles 120mA at 400V (AC/DC), has a 20Ω on-state resistance, and provides 5000Vrms isolation. It features fast opening (20μs) and slower closing (500μs). The device operates from -40°C to 85°C with 1.2-1.4VDC input.

Application Scenarios: Provides two high-voltage fail-safe channels. Used in high-voltage power supply safety circuits, X-ray generator interlock systems, and industrial process controls where two high-potential circuits need to be normally energized, with the ability to be rapidly disconnected for safety.
