EPC Expands EGaN FET Portfolio With 150 V Power Transistor

The new gallium nitride power transistor delivers high frequency switching for exceptional performance in DC-DC power conversion and Class D Audio applications


Efficient Power Conversion Corporation (EPC) is introducing the EPC2018 as the newest member of its family of enhancement mode gallium nitride power transistors.

The EPC2018 is a 5.76 mm2, 150 VDS, 12 A device with a maximum RDS(on) of 25 milliohms with 5V applied to the gate. This GaN power transistor delivers high performance due to its ultra high switching frequency, extremely low RDS(on), exceptionally low QG and in a very small package.



Compared to a state-of-the-art silicon power MOSFET with similar on-resistance, the EPC2018 is much smaller and has many times superior switching performance.

Applications that benefit from eGaN FET performance include high-speed DC-DC power supplies, point-of-load converters, class D audio amplifiers, as well as many other circuits needing nanosecond switching speeds.

“The EPC2018 is an excellent complement to our existing family of eGaN FETs. The low on resistance, low output capacitance, fast switching, and no reverse recovery reduce the switching losses in power conversion applications and allow for higher efficiency and improved sound quality in Class D audio applications," notes Alex Lidow, co-founder and CEO.

In 1k piece quantities, the EPC2018 is priced at $6.54 and is immediately available through Digi-Key Corporation

AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
