Automotive grade semiconductors are semiconductors specifically applied to automotive electronic systems, whose performance, reliability and environmental adaptability requirements are much higher than those of ordinary semiconductors. Automotive grade semiconductors can operate stably in a wider temperature range, higher vibration and shock environment to ensure the safety and reliability of automobiles.
Characteristics of Automotive Grade Electronic Components:
High Temperature Resistance: In-vehicle temperatures can range from -40°C to 150°C, so automotive-grade electronic components must be able to withstand extreme temperatures.
Vibration and Shock Resistant: Vehicles generate strong vibration and shock during driving, so automotive-grade electronic components must be able to withstand such shocks.
Humidity: When the car is driven in rainy or humid environment, the vehicle-grade electronic components must be able to prevent moisture-induced corrosion and short-circuit.
Electromagnetic Interference: There is a lot of electromagnetic interference around the car, so the car-grade electronic components must be able to resist such interference.
High Reliability: Failure of automotive-grade electronic components can lead to serious safety issues, so they must be highly reliable.
Automotive Grade Standards
Automotive grade electronic components must meet the appropriate industry standards to be called automotive grade. Currently, the most commonly used automotive-grade standards are the AEC-Q series of standards, developed by the Automotive Electronics Council (AEC).The AEC-Q series of standards covers a wide range of types of automotive-grade electronic components, including:
AEC-Q100: Standards applicable to discrete semiconductor components
AEC-Q101: Standard for Integrated Circuits
AEC-Q102: Standard for Optoelectronic components
AEC-Q103: Standard applicable to sensors and actuators
AEC-Q200: Standard for automotive cables and connectors
Applications of Automotive Grade Electronic Components
Automotive grade electronic components are widely used in a variety of automotive systems, including:
Engine Control System: Controls the working status of the engine, such as fuel injection, ignition timing, etc.
Transmission Control System: Controls the gearshift operation of the transmission.
Braking System: control of automobile braking.
Safety Systems: such as airbags, ABS, ESP, etc..
Infotainment System: e.g. navigation, audio, entertainment system, etc.
