AQY212GS Panasonic PhotoMOS Relay – GU Type, 1 Form A, 60 V, 1.0 A, SOP4
The Panasonic AQY212GS is a PhotoMOS relay from the GU series in a miniature SOP 4-pin surface-mount package. It is a 1 Form A (normally open) solid-state switch rated 60 V load voltage and 1.0 A continuous load current, and it switches both AC and DC loads. The input is a low-current LED (typically 1.1 mA to operate) and the output is a MOSFET with a typical on-resistance of just 0.34 Ω. It replaces mechanical signal relays with silent, wear-free switching and 1,500 Vrms input-to-output isolation. Typical uses include I/O boards, measurement equipment, security systems, telecom and battery-powered devices where board space and power consumption matter.
