Schottky Barrier Diode for Advanced Image Sensor Protection
ROHM Semiconductor has developed an innovative Schottky barrier diode, overcoming the conventional trade-off between VF and IR.
This diode provides high reliability protection for high-resolution image sensor applications, including ADAS cameras.
Challenges in ADAS Cameras
Modern ADAS cameras require higher pixel counts, creating a growing concern: the risk of damage caused by photovoltaic voltage generated under light exposure during power OFF.
- Low-VF SBDs are effective countermeasures.
- Low IR is vital during operation to stop thermal runaway.
Achieving low VF and IR simultaneously has been a longstanding technical challenge.
