AQV101A Photo-MOS Relay SPST-NO 40VDC 700mA SMD

The AQV101A is a compact surface-mount Photo-MOS relay designed for reliable solid-state DC switching. Featuring a SPST-NO (Form A) configuration, it supports up to 40VDC and 700mA load current, making it ideal for high-reliability electronic control applications. Using optical isolation and MOSFET output technology, the AQV101A provides silent, contactless switching without the mechanical wear associated with conventional relays. Its low maximum on-state resistance of 500m ensures efficient current flow with minimal power loss.

The relay is housed in a compact 6-SMD package with gull wing terminals for easy surface-mount PCB assembly, making it well suited for automated production environments and space-constrained electronic designs. With a low input control voltage of approximately 2.3VDC, it interfaces easily with logic circuits, microcontrollers, and PLC outputs.

Because it is a solid-state device, the AQV101A offers fast response, high durability, and excellent reliability in applications requiring frequent switching or long operational life.
