Automotive-qualified PhotoMOS®
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.
