Panasonic AQY210KS Photomos Relay SMD SPNO 350V

The Panasonic AQY210KS is a PhotoMOS® relay, a highly reliable solid-state solution featuring a single-pole, normally-open (SPST-NO, 1 Form A) contact configuration in a compact surface-mount (SMD) SOP-4 package. It employs a MOSFET output to control low-level analogue signals, providing precise switching for sensitive electronic circuits. A key advantage is its short-circuit protection latch mechanism, offering enhanced safety and device longevity in demanding applications.

This relay is designed to handle both AC and DC loads with a maximum load voltage of 350V and a load current of 120mA. Its construction ensures extremely low off-state leakage current, minimising power loss and signal interference in the 'off' state. The device also boasts a high 1500Vrms input/output isolation voltage, providing excellent electrical separation between control and load circuits for improved safety and noise immunity.

Ideal Applications

Its robust design and reliable performance make it suitable for a wide range of professional and industrial electronic equipment. It is commonly specified for use in modem and telephone infrastructure, precision measuring and testing instruments, security system control panels, and various types of industrial automation equipment. The wide operating ambient temperature range of -40°C to +85°C ensures dependable functionality in challenging environmental conditions.
