SiC semiconductors give an modern choice for power electronic designers who are searhing for improved procedure efficiency, lesser type issue and higher operating temperature within their solutions for industrial, transportation/automotive, health-related, aerospace/aviation, protection and conversation apps.

Japan’s ROHM claims that its silicon carbide (SiC) MOSFETs and SiC Schottky barrier diode (SBD) are being adopted by precision power analog firm Apex Microtechnology of Tucson, AZ, USA (a Section of HEICO Corp’s Electronics Systems Team) for the new line of power modules. The merchandise relatives currently consists of the a few-phase SA310 module, suited to driving superior-voltage BLDC motors, together with two 50 %-bridge products SA110 and SA111, ideal for a wide array of substantial-voltage apps. ROHM’s 1200V S4101 SiC MOSFETs and 650V S6203 SiC SBD are provided in bare die variety, enabling Apex to avoid wasting space and enhance the performance and reliability of its modules. Along with the SiC gadgets, Apex’s new line of power modules use ROHM’s tightly matched BM60212FV-C gate drivers in bare die format, contributing to substantial-effectiveness operation of substantial-voltage motors and power materials. Through the use of these parts in bare die kind, Apex has become in the position to enhance the amounts of integration made available from these power modules. According to a review commissioned by the corporate, this sort of modules are frequently 67% smaller sized than discrete methods produced by clients. Apex is frequently equipped to include not just MOSFETs, gate motorists and SBDs but will also bootstrap source and bypass capacitors with compact area-mount sort elements. “Apex Microtechnology’s portfolio of high-power, high-precision analog and combined-sign alternatives are used in some of the earth’s most demanding programs,” states the agency’s president Greg Brennan.

An additional significant advantage of these substrates is their superior resistance to thermal shock. This means they've got the chance to modify temperatures quickly without the need of breaking or cracking.

更高的击穿场强、更好的热稳定性、更高的电子饱和速度及禁带宽度等,能够大大提高功率器件的性能表现。总结来看,对比硅基器件,碳化硅功率器件主要有三大优势:

Reverse leakage current, since it raises with temperature, results in a thermal instability issue. This frequently boundaries the handy reverse voltage to well below the particular ranking.

上文已经介绍碳化硅功率器件在应用中有高转化效率、功率密度大、高频对外围组件体积的减少、耐高温、使用寿命长等优势,因此其在电力转换需求频繁、对电力转换组件有体积或重量要求、相对高温的使用环境上有得天独厚的优势。

It is possible to Examine two or even more form quantities by choice the checkboxes for the kind figures and click on Examine. All other rows will be hidden.

With in excess of 20 years of experience in the development, layout and help of SiC gadgets and power alternatives, we will let you undertake SiC easily, velocity and self-assurance.

Its toughness at higher temperatures also allows it to safely and securely function at temperatures in excess of 1600°C. This can make it click here an appropriate substrate for virtually any large temperature software.

In exactly the same voltage range, Silicon products clearly show a bipolar part resulting in Considerably larger switching losses. The graph exhibits the comparison amongst several 600V equipment.

By making use of these areas in bare die form, Apex has become capable to increase the levels of integration offered by these power modules. According to a examine commissioned by the corporate, this kind of modules usually are sixty seven% more compact than discrete methods made by clients.

Our solutions feature an oxide lifetime of much more than 100 many years and also a secure human body diode, coupled with most effective-in-course avalanche ruggedness, brief circuit functionality and neutron susceptibility.

The one of a kind electronic and thermal properties of silicon carbide (SiC) enable it to be Preferably fitted to State-of-the-art substantial-power and superior-frequency semiconductor devices that function well past the capabilities of both silicon or gallium arsenide devices. The main element benefits of SiC-based technological innovation contain diminished switching losses, bigger power density, improved heat dissipation, and increased bandwidth ability.
