Diodes Incorporated provides product designers with a broad range of discrete semiconductor components that are renowned for their quality, high performance and optimized packaging.

With its leading-edge bipolar technology, Diodes has long set the benchmark for bipolar transistor performance with very low saturation voltages and high power density components.


The best Analog ICs provide circuit designers with the most advantageous combination of efficiency, functionality and package size.

Diodes Incorporated is able to offer a portfolio of devices that meet the requirements of a wide range of electronic applications by addressing these competing design criteria to produce elegant and practical solutions.

As an expert in Analog electronics, Diodes Incorporated works closely with customers and partners to define the precise needs of a particular application and to identify the most appropriate integrated solution.


Diodes’ growing portfolio Power Management Solutions includes Low Drop Out (LDO) Voltage Regulators, µP Supervisors, and Power Management Solutions for Portable/Low Power Applications. These products offer customers superior performance in small packages to allow energy efficient power system design. Value-add features significantly reduce current consumption and provide design flexibility for product differentiation.



Diodes Incorporated's experienced design team has created popular functions in four major logic families. Very low power AUP products are available to save milliwatts and extend battery life. The LVC family is an industry standard that has the drive and speed to work well in many demanding applications. HC and AHC legacy parts have been re-engineered on advanced wafer processes allowing for a continuous product supply well into the future.

Diodes Incorporated provides an assortment of small package options, allowing manufacturers to choose a size and lead pitch that will be compatible with their standard manufacturing processes. Most of the logic products are assembled in Diodes Incorporated's proprietary factories, which enables direct control of quality and cost along with dedicated capacity to meet customer needs. While logic is often considered a commodity device, the newest miniature package offerings from Diodes Incorporated are enabling the advancement of the next generation of tiny portable consumer products.


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 TS16949 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.
