What is the AQY214EH and what does it switch?
The AQY214EH is a PhotoMOS™ AQY series solid-state relay from Panasonic Electric Works, configured as a SPST-NO (1 Form A) output that switches both AC and DC loads. It handles a load current of 120 mA across a voltage range of 0 V to 400 V, making it suitable for low-power signal switching in test equipment, instrumentation, and telecom line cards. The input side requires a 1.14 VDC drive, and the on-state resistance is a maximum of 35 Ohms — a figure that governs the voltage drop across the relay at the rated load current.
Package and board integration
Supplied in a tube; the base product number AQY214 covers the family variants, with the EH suffix denoting the specific input voltage and package option.
