AEC-Q101 qualified SiC Schottky Barrier Diodes

As vehicle electrification continues rapid growth worldwide, innovative power technologies such as Silicon Carbide (SiC) are required for high-voltage automotive systems ranging from motors to on-board charging and DC/DC converters.

For EV power designers who need to increase system efficiency while maintaining high quality, Microchip’s AEC-Q101-qualified devices maximise system reliability and ruggedness and enable stable and lasting application life. The devices’ superior avalanche performance allows designers to reduce the need for external protection circuits, reducing system cost and complexity.

“As a long-time supplier to the automotive industry, Microchip’s continued expansion of automotive-capable power solutions is leading the transformation of power systems in vehicle electrification,” said Leon Gross, Vice President of Microchip’s discrete product business unit. “Our focus is to provide automotive solutions that help our clients easily transition to SiC while minimising the risk of quality, supply and support challenges.”

Microchip has been a supplier to the automotive industry for more than 25 years. The company’s SiC technology, as well as its multiple IATF 16949:2016-certified fabrication facilities, provide high-quality devices through flexible manufacturing alternatives, helping minimise risk in the supply chain. 

Microchip’s SiC automotive power devices complement its broad portfolio of controllers, analogue and connectivity solutions providing designers with total system solutions for electric vehicles and charging stations. Microchip also provides a broad portfolio of 700, 1200 and 1700V SiC SBD and Metal Oxide Silicon Field Effect Transistor (MOSFET) power modules utilising its newest generation of SiC die.

In addition, its dsPIC digital signal controllers deliver performance, low power consumption and flexible peripherals. Microchip’s AgileSwitch family of digital programmable gate drivers further accelerates the process of moving from the design stage to production. These solutions also have applications across renewable, grid, industrial, transportation, medical, data center and aerospace and defense systems.

Microchip’s AEC-Q101-qualified SiC SBD devices are supported with SPICE and PLECS simulation models and MPLAB Mindi Analog Simulator. Also available is a PLECS reference design model that uses Microchip’s SBDs (1200V, 50A) as part of the power stage — the Vienna three-Phase Power Factor Correction (PFC) reference design.

Microchip’s AEC-Q101 qualified 700 and 1200V SiC SBD devices (also available as die for power modules) for automotive applications are available now for volume production orders.
