PhotoMOS relays for passenger safety

The car chassis must be reliably galvanically-isolated from the HV battery. Automotive PhotoMOS relays can be used as fast electronic switches in order to detect leakage currents in a isolation-monitoring application.

Key Features

  • Available for high voltages up to 1500V
  • Minimal leakage current (typ. <1nA)
  • Turn-on time: max. 0.5ms - 1.0ms
  • Turn-off time: max. 0.5ms
  • Tested according to AEC-Q101
  • Input/output isolation ≤5kVrms
  • No threshold voltage
  • Stable On-resistance over entire lifetime
  • Highly resistant to shock and vibration 

Isolation monitoring

AQV PhotoMOS relay isolation monitoring

PhotoMOS© technology is used to check the isolation between high voltage (HV) and low voltage (LV) in hybrid and electronic vehicles (HEV/EV). In connection with high-ohmic resistors (shunts), the secure separation of the high voltage and low voltage sides of the electrical system can be checked.
