ST introduces new automotive quality grade silicon carbide diodes

China, December 17, 2014 - Introducing new automotive quality grades across multiple electronic applications, the world's leading semiconductor supplier, power chip maker STMicroelectronics (ST; NYSE: STM) Silicon Carbide (SiC) Diodes to meet the high power of on-board battery chargers in electric vehicles and plug-in hybrids (PHEVs, Plug-in Hybrids) Demanding requirements.

These diodes allow designers to develop smaller power modules that not only benefit automotive power systems, but also make them a key choice to overcome the challenges of inverter miniaturization proposed by Google and IEEE. Google’s $1 million prize collection is smaller than one-tenth of the existing inverters and is suitable for a variety of applications, especially the kilowatt-scale inverter design of a solar micro-generator; France Semiconductor is a partner in this open challenge.

The new diodes use advanced technology to prevent high-current spikes from burning out the device. For safety reasons, designers are still using diodes too much. New products developed by STMicroelectronics have revolutionized this situation. The overcurrent protection value is 2.5 times the rated current value, so designers can choose smaller, more economical and less reliable and energy-efficient currents. Diode.

ST's new silicon carbide diodes are tested in automotive grades, and the polarity reversal breakdown voltage is increased to 650V, which meets the designer's and automotive manufacturers' desire to reduce the voltage deraTIng factor to ensure on-board rechargeable semiconductor elements. There is a sufficient safety margin between the nominal voltage of the device and the peak voltage.

As a Wideband-Gap (WBG) technology, silicon carbide has a well-known energy efficiency advantage. Compared with the size of the component itself, it compares the switching loss and the voltage raTIng. Better than traditional silicon diodes. The 650V diodes introduced this time include the 10A STPSC10H065DY in the TO-220AC power package and the 12A STPSC12H065DY in the TO-220AC package. In addition, the STPSC20H065CTY in the TO-220AB package and the STPSC20H065CWY in the TO-247 package are dual-diodes with two 10A diodes to maximize space utilization and reduce the weight of the car charger.
