Semiconductors form an integral part of modern automobiles. A typical vehicle may have up to 100 electronic control units (ECU’s) embedded in systems which include those governing engine, transmission, active safety, passenger comfort and infotainment.

Diodes Incorporated has created a wide portfolio of automotive-compliant analog, discrete and timing products. These parts are clearly identified by a ‘Q’ at the end of the part number. The advantage of Automotive Diodes’ products is that they offer a wide range of solutions for various automotive applications. Our LIN transceiver and automotive Ethernet solutions enable Advanced Driver Assistance System and Infotainment and Telematics application. Diodes’ devices for body control modules help monitor the vehicle’s battery sensors, and control motor and power to analogous loads in the car.

Our Automotive P-channel and N-channel MOSFETs protect against reverse polarity connection of the battery during vehicle maintenance. They feature simple, low cost and minimal component count, minimal power losses, and pulse ruggedness to ISO7637. Diodes’ range of Hall Effect Switch ICs offer contactless sensing of any moving part, including rotation sensing, allowing lateral and rotational position detection and measurement.

Diodes fully automotive-compliant ‘Q’ parts are all qualified to AEC-Q100, AEC-Q101 and AEC-Q200 respectively, and are manufactured in facilities qualified to the rigorous IATF16949 standard, and capable of customer audit to VDA6.3. These parts are all supported by PPAP (Production Part Approval Process) documentation, thus meeting all the requirements of the Automotive electronics industry.
