SMD solid state relay AQW series

PhotoMOS

Automotive grade PhotoMOS relays provide enhanced quality controls. 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 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.
