The latest PhotoMOS® HE relay series from Panasonic Industry Europe offers 5-kV I/O isolation and an increased clearance and creepage distance on output side, plus miniature 1-Form-A DIP5 packaging. This makes the relays particularly suitable for Battery Management Systems (BMS) switching applications in storage systems, charging stations, and numerous other high voltage measurement and infrastructure control applications.
”Industrial BMS applications demand reliability and consistent performance over the product lifespan”, says Michael Renner, Product Manager at Panasonic Industry Europe. “These new devices extend the load voltage of Panasonic’s PhotoMOS® relay family and improve ruggedness and stability.”
Rated at 1500-V/20-mA, new AQV258H5 HE series PhotoMOS® relays have a MOSFET output and enjoy an almost unlimited lifetime if used according to the specifications. On-resistance remains stable throughout the entire lifetime — and AQV258H5 HE series PhotoMOS® relays — unlike electromechanical devices — are unaffected by vibration, a significant benefit in many industrial applications.
The PhotoMOS® series AQV258H5 relays also feature a low control current and low leakage current and produce no switching noise. Devices come with 5 pins to accomodate different creepage and clearance requirements, but a 6 pin version is also available.Both types are offered with through-hole or surface-mount terminations.
PhotoMOS® relays with a MOSFET output enjoy an almost unlimited lifetime if used according to the specifications. Moreover, they are extremely reliable, unaffected by vibration, and their On-resistance remains stable throughout their entire lifetime.
Panasonic also offer a variety of other PhotoMOS® relays in including automotive grade devices, which enable the car chassis to be reliably galvanically-isolated from the high-voltage battery. Automotive PhotoMOS® relays can be used as fast electronic switches in order to detect leakage currents in an isolation-monitoring application. Other applications include battery monitoring and final processing.
