China, December 17, 2014 - New automotive quality class introduced across multiple electronics applications, global leading semiconductor supplier, power chip maker STMicroelectronics (ST; New York Stock Exchange code: STM) Silicon Carbide (SiC) Diodes to Meet New Energy Vehicles such as Electric Vehicles and Plug-in Hybrids (PHEVs) and plug-in hybrids (OBCs) to handle high power in limited space for on-board battery chargers (OBCs) The demanding requirements.
These diodes allow designers to develop smaller power modules that not only benefit the automotive power system, but also make it a key choice to overcome the challenge of miniaturization of inverters proposed by Google and IEEE. Google's contribution of up to $1 million in prize money is less than one-tenth that of existing inverters, and is suitable for various applications, especially the solar micro-generator's kilowatt-level inverter design; Law 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. The new product developed by STMicroelectronics has completely changed this situation. The over-current protection value is 2.5 times the rated current value, so designers can choose to use smaller, more economical, and less current that will not affect reliability and energy efficiency. Diodes.
ST's new silicon carbide diodes have been tested in automotive-grade products. The polarity reverse breakdown voltage has been increased to 650V to meet the requirements of designers and automotive manufacturers to reduce the voltage derating factor to ensure the on-vehicle charging of semiconductor elements. There is a sufficient safety margin between the nominal voltage of the device and the peak voltage.
Silicon Carbide (WBG), as a Wide Band-Gap (WBG) technology, has a well-known energy efficiency advantage. Compared with the size of a component itself, it compares the switching loss and the voltage rating, and the new products are Superior to traditional silicon diodes. The 650V diodes introduced this time include 10A STPSC10H065DY in TO-220AC power package and 12A STPSC12H065DY in TO-220AC package. In addition, the STPSC20H065CTY in the TO-220AB package and the STPSC20H065CWY in the TO-247 package are dual-diode products with two 10A diodes to maximize space efficiency and reduce the weight of the car charger.
