Panasonic has introduced the AQY217GS, a new series of high-power PhotoMOS® optically-isolated relays in a small package which maintain a low on-resistance.
The 1 Form A AQY217GS relays, which are supplied in a four-pin SOP surface-mount package measuring 4.3mm x 4.4mm x 2.1mm, are capable of handling up to 400mA at 200V. They can handle both AC and DC loads.
The relays also feature low on-resistance of 1.8Ω, helping to reduce heat dissipation while accelerating turn-on activation. Typical turn-on time is 1.2ms, and turn-off time is 0.03ms.
Panasonic’s PhotoMOS relays can sometimes be used in applications in which traditional electromechanical relays are used.
Replacing a standard electromechanical relay with a PhotoMOS device can provide additional benefits such as:
- Longer life cycle
- Better resistance to shock and vibration
- Lower on-resistance
This makes PhotoMOS relays a good solution for the test and measurement, electrical power and industrial markets.
