Fairchild's new extended temperature medium voltage MOSFETs are rated at 175° C for ultra high power density applications

Fairchild, a global leader in high-performance power semiconductor solutions, is revolutionizing product reliability and performance with its expanded lineup of extended temperature (ET) medium voltage MOSFETs that operate at 175°C. These advanced components offer an 85% increase in power density and are three times more reliable than standard 150°C MOSFETs. This makes them ideal for applications where high temperatures are a common challenge. The new ET MOSFET family meets the IPC-9592 power conversion standard, allowing a maximum junction temperature of up to 150°C—far exceeding the 125°C limit of conventional 150°C-rated devices. This provides greater design flexibility and margin for engineers. The product line includes 19 new devices available in standard 5mm x 6mm and 3mm x 3mm packages, as well as a new TO-Leadless (TO-LL) package. Voltage ratings range from 30V to 150V, offering a wide selection for various applications. Designed for DC-DC, AC-DC, and motor drive systems, these MOSFETs are particularly suited for avionics, miniature solar inverters, power tools, and telecommunications. Suman Narayan, Vice President of Fairchild’s iFET product line, emphasized that these devices allow designers to achieve better margins without relying on heat sinks or complex cooling methods. “They inherit Fairchild’s legacy of innovation and provide superior solutions that outperform competing products,” he said. Operating at 175°C makes these MOSFETs perfect for high-temperature environments like solar and Power over Ethernet (PoE) applications. Their enhanced reliability also benefits equipment used in harsh conditions, such as aviation, rail systems, and industrial tools. The combination of extended temperature range, high power density, and ultra-small packaging gives manufacturers more freedom in product design. Engineers can now reduce device size while maintaining or even increasing power output without compromising performance. Fairchild will showcase these innovations at the 2015 APEC exhibition from March 16–19 in Charlotte, North Carolina, at booth #905. Technical experts will be on hand to discuss ET MOSFETs and other energy-efficient solutions.

Dual Band Router Module

Dual-band WiFi module refers to the WiFi module that supports both 2.4GHZ and 5GHz bands. The dual-band WiFi module can operate in the 5Ghz band, which is much cleaner and can easily avoid interfering with each other. The advantage of 2.4G is that it has good ability to penetrate the wall, and the disadvantage is that it is easy to be disturbed. The advantages of 5G are strong anti-interference ability, wide band width, high throughput rate, and strong scalability, but the disadvantage is that 5G is only suitable for indoor small-range coverage and outdoor bridge, and the attenuation effect of various obstacles on it is much larger than 2.4g.

Dual-band WiFi module has a stronger and more stable Wifi wireless signal, higher transmission speed, and can make wireless devices more power-saving, to meet the future high-definition and big data wireless transmission needs.

When selecting a dual-frequency WiFi module, we should pay attention to these parameters of the WiFi module: size, package, frequency range, data rate, transmission rate, transmission distance, communication interface, power supply voltage, antenna interface, etc.

Dual frequency WiFi module can well meet the functional needs of users, increase the competitiveness of the product, while the WiFi module is easy to use, can shorten the user product development cycle, speed up the product market! Users can make choices according to actual needs!


Choosing a dual-band WiFi module may need to pay attention to the following points:

(1) Consider the transmission power of the dual-frequency WiFi module

The transmitting power of the WIFI module is generally about 18dBm, and the transmitting power of the high-power WIFI module is about 28dBm.

(2) Transmission rate

Consider whether the dual-band WiFi module supports MIMO technology (that is, allows multiple antennas to send and receive multiple spatial streams simultaneously)

(3) Consider the application interface that dual-band WiFi modules can provide, which is also very important.

(4) According to the requirements of the application scenario to choose the dual-band WiFi module, not the higher the configuration, the better, the application is good, excess waste!
