Application specific MOSFETs are optimised for automotive airbags

Application specific MOSFETs (ASFETs) for automobile airbag applications, have been released by Nexperia. The BUK9M20-60EL, single N-channel 60V, 13 mOhm logic level MOSFET is in a LFPAK33 packaging. 

Nexperia explained that ASFETs have been specifically designed and optimised for use in one application and that the BUK9M20-60EL joins a range of other ASFETs which Nexperia provides for battery isolation, motor control, hot-swap, and power over Ethernet (PoE) applications.

The BUK9M20-60EL uses Nexperia’s new enhanced safe operating area (SOA) technology which has been tailored to provide transient linear mode performance which is a key performance metric in airbag applications. The BUK9M20-60EL achieves this performance in new LFPAK33 packaging which uses 84 per cent less board space when compared to older DPAK packaging.

“Other similar products use older DPAK packaging and are typically based on DMOS and first-generation trench technologies which are being gradually retired by many silicon manufacturers,” according to Norman Stapelberg, senior product marketing manager at Nexperia. “This portfolio of ASFETs uses a combination of the latest silicon trench technology and LFPAK packaging, allowing it to meet the most recent reliability standards. Using the latest manufacturing and packaging technologies makes the supply chain more sustainable,” he added.

Nexperia produces high-volume components and offers a portfolio which includes diodes, bipolar transistors, ESD protection devices, MOSFETs, GaN FETs and analogue and logic ICs. 

Headquartered in Nijmegen, the Netherlands, Nexperia annually ships more than 100 billion products, meeting the stringent standards set by the automotive industry. These products are recognised as benchmarks in efficiency – in process, size, power, and performance — with small packages that save valuable energy and space.

Nexperia has over 14,000 employees across Asia, Europe, and the US. Nexperia, a subsidiary of Wingtech Technology Co., Ltd. (600745.SS), has an extensive IP portfolio and is certified to IATF 16949, ISO 9001, ISO 14001, and ISO 45001.
