Panasonic’s PhotoMOS HE relay series offers 5kV I/O isolation and an increased clearance and creepage distance on output side, plus miniature 1-Form-A DIP5 packaging, making it a suitable switching device for Battery Management Systems (BMS) in storage systems, charging stations, and numerous other high voltage measurement and infrastructure control applications.
“These devices extend the load voltage of Panasonic’s PhotoMOS relay family and improve ruggedness and stability,” says Panasonic’s Michael Renner.
Rated at 1,500V/20mA, 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 relays have 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.
